+// [dtype Macros note] For the macros below:
+//
+// For users: If you want to macro some code for all non-QInt scalar types
+// (i.e. types with complete information, you probably want one of the
+// AT_FORALL_SCALAR_TYPES / AT_FORALL_SCALAR_TYPES_AND macros below, which are
+// designed to behave similarly to the Dispatch macros with the same name.
+//
+// For adding a new dtype: In the beginning, we had an idea that there was a
+// list of all scalar types, and you could use AT_FORALL_SCALAR_TYPES to
+// iterate over them.  But over the years we added weird types which couldn't
+// be handled uniformly everywhere and so in the end we ended up with some
+// mish-mosh of some helper macros, but mostly use sites making a call about
+// what dtypes they can or can't support.  So if you want to add a new dtype,
+// the preferred resolution is to find a dtype similar to what you want,
+// grep for it and edit all the sites you find this way.  If you need to add
+// a completely new kind of dtype, you're going to have to laboriously audit
+// all of the sites everywhere to figure out how it should work.  Consulting
+// some old PRs where we added new dtypes (check history of this file) can
+// help give you an idea where to start.
+
+// If you want to support ComplexHalf for real, add ComplexHalf
+// into this macro (and change the name).  But beware: convert()
+// doesn't work for all the conversions you need...
+//
+// TODO: To add unsigned int types here, we must define accumulate type.
+// But uint8 currently accumulates into int64, so we would have to make
+// an inconsistent choice for the larger types.  Difficult.

+/// s eeee mmm
+/// 1 sign bit
+/// 4 exponent bits
+/// 3 mantissa bits
+/// The key differences versus Float8_e4m3fn are:

+/// no infinities or negative zero
+/// NaN only when sign bit is 1, rest all 0s
+///
+/// Implementation based on the paper https://arxiv.org/pdf/2206.02915.pdf and

+/// Defines the Float8_e5m2fnuz type (8-bit floating-point) including
+/// conversions to standard C types and basic arithmetic operations. Note that
+/// arithmetic operations are implemented by converting to floating point and
+/// performing the operation in float32.
+/// Binary configuration remains the same as e5m2:
+/// s eeeee mm
+/// 1 sign bit
+/// 5 exponent bits
+/// 2 mantissa bits
+/// The key differences that e5m2fnuz brings are:
+/// bias = 16
+/// no infinities or negative zero
+/// NaN only when sign bit is 1, rest all 0s
+///
+/// Implementation based on the paper https://arxiv.org/pdf/2206.02915.pdf and
+/// the existing Float8_e4m3fn implementation.

+   *   - Then we multiply the single-precision result of exponent adjustment by

+   *     The floating-point multiplication hardware would ensure than Inf and

+/// in headers. This will be a base class from which ArrayRef inherits, so that
+/// we can keep much of the implementation shared.
+///
+/// [HeaderOnlyArrayRef vs ArrayRef note]
+/// As HeaderOnlyArrayRef is a subset of ArrayRef, it has slightly less
+/// functionality than ArrayRef. We document the minor differences below:
+/// 1. ArrayRef has an extra convenience constructor for SmallVector.
+/// 2. ArrayRef uses TORCH_CHECK. HeaderOnlyArrayRef uses header-only
+///    STD_TORCH_CHECK, which will output a std::runtime_error vs a
+///    c10::Error. Consequently, you should use ArrayRef when possible
+///    and HeaderOnlyArrayRef only when necessary to support headeronly code.
+/// In all other aspects, HeaderOnlyArrayRef is identical to ArrayRef, with the
+/// positive benefit of being header-only and thus independent of libtorch.so.

+// Most of the APIs duplicates std::complex
+// Reference: https://en.cppreference.com/w/cpp/numeric/complex
+//
+// [NOTE: Complex Operator Unification]
+// Operators currently use a mix of std::complex, thrust::complex, and
+// c10::complex internally. The end state is that all operators will use
+// c10::complex internally.  Until then, there may be some hacks to support all
+// variants.
+//
+//
+// [Note on Constructors]
+//
+// The APIs of constructors are mostly copied from C++ standard:
+//   https://en.cppreference.com/w/cpp/numeric/complex/complex
+//
+// Since C++14, all constructors are constexpr in std::complex
+//
+// There are three types of constructors:
+// - initializing from real and imag:
+//     `constexpr complex( const T& re = T(), const T& im = T() );`
+// - implicitly-declared copy constructor
+// - converting constructors
+//
+// Converting constructors:
+// - std::complex defines converting constructor between float/double/long
+// double,
+//   while we define converting constructor between float/double.
+// - For these converting constructors, upcasting is implicit, downcasting is
+//   explicit.
+// - We also define explicit casting from std::complex/thrust::complex
+//   - Note that the conversion from thrust is not constexpr, because
+//     thrust does not define them as constexpr ????
+//
+//
+// [Operator =]
+//
+// The APIs of operator = are mostly copied from C++ standard:
+//   https://en.cppreference.com/w/cpp/numeric/complex/operator%3D
+//
+// Since C++20, all operator= are constexpr. Although we are not building with
+// C++20, we also obey this behavior.
+//
+// There are three types of assign operator:
+// - Assign a real value from the same scalar type
+//   - In std, this is templated as complex& operator=(const T& x)
+//     with specialization `complex& operator=(T x)` for float/double/long
+//     double Since we only support float and double, on will use `complex&
+//     operator=(T x)`
+// - Copy assignment operator and converting assignment operator
+//   - There is no specialization of converting assignment operators, which type
+//   is
+//     convertible is solely dependent on whether the scalar type is convertible
+//
+// In addition to the standard assignment, we also provide assignment operators
+// with std and thrust
+//
+//
+// [Casting operators]
+//
+// std::complex does not have casting operators. We define casting operators
+// casting to std::complex and thrust::complex
+//
+//
+// [Operator ""]
+//
+// std::complex has custom literals `i`, `if` and `il` defined in namespace
+// `std::literals::complex_literals`. We define our own custom literals in the
+// namespace `c10::complex_literals`. Our custom literals does not follow the
+// same behavior as in std::complex, instead, we define _if, _id to construct
+// float/double complex literals.
+//
+//
+// [real() and imag()]
+//
+// In C++20, there are two overload of these functions, one it to return the
+// real/imag, another is to set real/imag, they are both constexpr. We follow
+// this design.
+//
+//
+// [Operator +=,-=,*=,/=]
+//
+// Since C++20, these operators become constexpr. In our implementation, they
+// are also constexpr.
+//
+// There are two types of such operators: operating with a real number, or
+// operating with another complex number. For the operating with a real number,
+// the generic template form has argument type `const T &`, while the overload
+// for float/double/long double has `T`. We will follow the same type as
+// float/double/long double in std.
+//
+// [Unary operator +-]
+//
+// Since C++20, they are constexpr. We also make them expr
+//
+// [Binary operators +-*/]
+//
+// Each operator has three versions (taking + as example):
+// - complex + complex
+// - complex + real
+// - real + complex
+//
+// [Operator ==, !=]
+//
+// Each operator has three versions (taking == as example):
+// - complex == complex
+// - complex == real
+// - real == complex
+//
+// Some of them are removed on C++20, but we decide to keep them
+//
+// [Operator <<, >>]
+//
+// These are implemented by casting to std::complex
+//
+//
+//
+// TODO(@zasdfgbnm): c10::complex<c10::Half> is not currently supported,
+// because:
+//  - lots of members and functions of c10::Half are not constexpr
+//  - thrust::complex only support float and double

+

+
+    - Empty containers like `[]` and `{}`, which TorchScript assumes to be container of `Tensor`
+    - Optional types like `Optional[T]` but assigned a valid value of type `T`, TorchScript would assume
+      it is type `T` rather than `Optional[T]`
+

+    is executed in eager mode. To annotate types of `torch.nn.Module` attributes,

+    Create an asynchronous task executing `func` and a reference to the value of the result of this execution.
+
+    `fork` will return immediately, so the return value of `func` may not have been computed yet. To force completion
+    of the task and access the return value invoke `torch.jit.wait` on the Future. `fork` invoked
+    with a `func` which returns `T` is typed as `torch.jit.Future[T]`. `fork` calls can be arbitrarily
+    nested, and may be invoked with positional and keyword arguments.
+    Asynchronous execution will only occur when run in TorchScript. If run in pure python,
+    `fork` will not execute in parallel. `fork` will also not execute in parallel when invoked
+    while tracing, however the `fork` and `wait` calls will be captured in the exported IR Graph.
+
+    .. warning::

+class AttributeTypeIsSupportedChecker(ast.NodeVisitor):
+    """Check the ``__init__`` method of a given ``nn.Module``.
+
+    It ensures that all instance-level attributes can be properly initialized.
+
+    Specifically, we do type inference based on attribute values...even
+    if the attribute in question has already been typed using
+    Python3-style annotations or ``torch.jit.annotate``. This means that
+    setting an instance-level attribute to ``[]`` (for ``List``),
+    ``{}`` for ``Dict``), or ``None`` (for ``Optional``) isn't enough
+    information for us to properly initialize that attribute.
+
+    An object of this class can walk a given ``nn.Module``'s AST and
+    determine if it meets our requirements or not.
+
+    Known limitations
+    1. We can only check the AST nodes for certain constructs; we can't
+    ``eval`` arbitrary expressions. This means that function calls,
+    class instantiations, and complex expressions that resolve to one of
+    the "empty" values specified above will NOT be flagged as
+    problematic.
+    2. We match on string literals, so if the user decides to use a
+    non-standard import (e.g. `from typing import List as foo`), we
+    won't catch it.
+
+    Example:
+        .. code-block:: python
+
+            class M(torch.nn.Module):
+                def fn(self):
+                    return []
+
+                def __init__(self) -> None:

+                    self.x = x
+                    return 1
+
+        The above code will pass the ``AttributeTypeIsSupportedChecker``
+        check since we have a function call in ``__init__``. However,
+        it will still fail later with the ``RuntimeError`` "Tried to set
+        nonexistent attribute: x. Did you forget to initialize it in
+        __init__()?".

+        In STATIC fusion, fused ops are compiled to have fixed input shapes. The shape is determined
+        based on some initial profiling runs.
+        In DYNAMIC fusion, fused ops are compiled to have variable input shapes, so that multiple
+        shapes are possible.
+
+    In both cases, we also recompile on new striding behavior, device, or dtype.
+
+    Behavior - fallback functions & depth:
+        When an input doesn't match the format required by the specialized compiled op, it will run
+        a fallback function. Fallback functions are recursively be compiled and specialized based
+        on the observed tensor shapes. Since compilation can be slow, the "depth" parameter is provided to
+        limit the number of specializations that can be compiled, before giving up on recompiling and
+        falling back to a completely un-fused, un-specialized implementation.
+
+    The list of (type, depth) pairs controls the type of specializations and the number of
+    specializations. For example: [("STATIC", 2), ("DYNAMIC", 2)] indicates that the first
+    two specializations will use static fusions, the following two specializations will use
+    dynamic fusion, and any inputs that satisfy none of the 4 options will run an

+    This method is a pass-through function that returns `value`, mostly
+    used to indicate to the TorchScript compiler that the left-hand side
+    expression is a class instance attribute with type of `type`. Note that
+    `torch.jit.Attribute` should only be used in `__init__` method of `jit.ScriptModule`
+    subclasses.
+
+    Though TorchScript can infer correct type for most Python expressions, there are some cases where
+    type inference can be wrong, including:
+
+    - Empty containers like `[]` and `{}`, which TorchScript assumes to be container of `Tensor`
+    - Optional types like `Optional[T]` but assigned a valid value of type `T`, TorchScript would assume
+      it is type `T` rather than `Optional[T]`
+
+    In eager mode, it is simply a pass-through function that returns `value`
+    without other implications.

+        r"""Retain the existing isinstance(ScriptModule) behavior.
+
+        The core data structure in TorchScript is the ``ScriptModule``. It is an
+        analogue of torch's ``nn.Module`` and represents an entire model as a tree of
+        submodules. Like normal modules, each individual module in a ``ScriptModule`` can
+        have submodules, parameters, and methods. In ``nn.Module``\s methods are implemented
+        as Python functions, but in ``ScriptModule``\s methods are implemented as
+        TorchScript functions, a statically-typed subset of Python that contains all
+        of PyTorch's built-in Tensor operations. This difference allows your
+        ``ScriptModule``\s code to run without the need for a Python interpreter.
+
+        ``ScriptModule``\s should not be created manually, instead use
+        either :func:`tracing <torch.jit.trace>` or :func:`scripting <torch.jit.script>`.
+        Tracing and scripting can be applied incrementally and :ref:`composed as necessary <Types>`.
+
+        * Tracing records the tensor operations as executed with a set of example inputs and uses these
+          operations to construct a computation graph. You can use the full dynamic behavior of Python with tracing,
+          but values other than Tensors and control flow aren't captured in the graph.
+
+        * Scripting inspects the Python code of the model
+          and compiles it to TorchScript. Scripting allows the use of many `types`_ of values and supports dynamic control flow.
+          Many, but not all features of Python are supported by the compiler, so changes to the source code may be necessary.

+    r"""Script the function.
+
+    Scripting a function or ``nn.Module`` will inspect the source code, compile
+    it as TorchScript code using the TorchScript compiler, and return a :class:`ScriptModule` or
+    :class:`ScriptFunction`. TorchScript itself is a subset of the Python language, so not all
+    features in Python work, but we provide enough functionality to compute on
+    tensors and do control-dependent operations. For a complete guide, see the
+    :ref:`language-reference`.
+
+    Scripting a dictionary or list copies the data inside it into a TorchScript instance than can be
+    subsequently passed by reference between Python and TorchScript with zero copy overhead.
+
+    ``torch.jit.script`` can be used as a function for modules, functions, dictionaries and lists
+     and as a decorator ``@torch.jit.script`` for torchscript-classes and functions.
+
+    Args:
+        obj (Callable, class, or nn.Module):  The ``nn.Module``, function, class type,
+                                                  dictionary, or list to compile.
+        example_inputs (Union[List[Tuple], Dict[Callable, List[Tuple]], None]): Provide example inputs
+            to annotate the arguments for a function or ``nn.Module``.
+
+    Returns:
+        If ``obj`` is ``nn.Module``, ``script`` returns
+        a :class:`ScriptModule` object. The returned :class:`ScriptModule` will
+        have the same set of sub-modules and parameters as the
+        original ``nn.Module``. If ``obj`` is a standalone function,
+        a :class:`ScriptFunction` will be returned. If ``obj`` is a ``dict``, then
+        ``script`` returns an instance of `torch._C.ScriptDict`. If ``obj`` is a ``list``,
+        then ``script`` returns an instance of `torch._C.ScriptList`.
+
+    **Scripting a function**
+        The ``@torch.jit.script`` decorator will construct a :class:`ScriptFunction`
+        by compiling the body of the function.
+
+        Example (scripting a function):
+
+        .. testcode::
+
+            import torch
+
+            @torch.jit.script
+            def foo(x, y):
+                if x.max() > y.max():
+                    r = x
+                else:
+                    r = y
+                return r
+
+            print(type(foo))  # torch.jit.ScriptFunction
+
+            # See the compiled graph as Python code
+            print(foo.code)
+
+            # Call the function using the TorchScript interpreter
+            foo(torch.ones(2, 2), torch.ones(2, 2))
+
+        .. testoutput::
+            :hide:
+
+            ...
+
+    ****Scripting a function using example_inputs**
+        Example inputs can be used to annotate a function arguments.
+
+        Example (annotating a function before scripting):
+
+        .. testcode::
+
+            import torch
+
+            def test_sum(a, b):
+                return a + b
+
+            # Annotate the arguments to be int
+            scripted_fn = torch.jit.script(test_sum, example_inputs=[(3, 4)])
+
+            print(type(scripted_fn))  # torch.jit.ScriptFunction
+
+            # See the compiled graph as Python code
+            print(scripted_fn.code)
+
+            # Call the function using the TorchScript interpreter
+            scripted_fn(20, 100)
+
+        .. testoutput::
+            :hide:
+
+            ...
+
+    **Scripting an nn.Module**
+        Scripting an ``nn.Module`` by default will compile the ``forward`` method and recursively
+        compile any methods, submodules, and functions called by ``forward``. If a ``nn.Module`` only uses
+        features supported in TorchScript, no changes to the original module code should be necessary. ``script``
+        will construct :class:`ScriptModule` that has copies of the attributes, parameters, and methods of
+        the original module.
+
+        Example (scripting a simple module with a Parameter):
+
+        .. testcode::
+
+            import torch
+
+            class MyModule(torch.nn.Module):
+                def __init__(self, N, M):
+                    super().__init__()
+                    # This parameter will be copied to the new ScriptModule
+                    self.weight = torch.nn.Parameter(torch.rand(N, M))
+
+                    # When this submodule is used, it will be compiled
+                    self.linear = torch.nn.Linear(N, M)
+
+                def forward(self, input):
+                    output = self.weight.mv(input)
+
+                    # This calls the `forward` method of the `nn.Linear` module, which will
+                    # cause the `self.linear` submodule to be compiled to a `ScriptModule` here
+                    output = self.linear(output)
+                    return output
+
+            scripted_module = torch.jit.script(MyModule(2, 3))
+
+        Example (scripting a module with traced submodules):
+
+        .. testcode::
+
+            import torch
+            import torch.nn as nn
+            import torch.nn.functional as F
+
+            class MyModule(nn.Module):
+                def __init__(self) -> None:
+                    super().__init__()

+    Save an offline version of this module for use in a separate process.
+
+    The saved module serializes all of the methods, submodules, parameters, and
+    attributes of this module. It can be loaded into the C++ API using
+    ``torch::jit::load(filename)`` or into the Python API with
+    :func:`torch.jit.load <torch.jit.load>`.
+
+    To be able to save a module, it must not make any calls to native Python
+    functions.  This means that all submodules must be subclasses of
+    :class:`ScriptModule` as well.
+
+    .. DANGER::
+        All modules, no matter their device, are always loaded onto the CPU
+        during loading.  This is different from :func:`torch.load`'s semantics
+        and may change in the future.
+
+    Args:
+        m: A :class:`ScriptModule` to save.
+        f: A file-like object (has to implement write and flush) or a string
+           containing a file name.
+        _extra_files: Map from filename to contents which will be stored as part of `f`.
+
+    .. note::
+        torch.jit.save attempts to preserve the behavior of some operators
+        across versions. For example, dividing two integer tensors in
+        PyTorch 1.5 performed floor division, and if the module
+        containing that code is saved in PyTorch 1.5 and loaded in PyTorch 1.6
+        its division behavior will be preserved. The same module saved in
+        PyTorch 1.6 will fail to load in PyTorch 1.5, however, since the
+        behavior of division changed in 1.6, and 1.5 does not know how to
+        replicate the 1.6 behavior.

+    Verify that a JIT compiled model has the same behavior as its uncompiled version along with its backwards pass.
+
+    If your model returns multiple outputs,
+    you must also specify a `loss_fn` to produce a loss for which
+    the backwards will be computed.
+
+    This function has side-effects (e.g., it executes your model / saves and loads
+    parameters), so don't expect the model to come out exactly the same as what
+    you passed in.
+
+    Args:
+        model (compiled torch.nn.Module or function): the module/function to be
+            verified.  The module/function definition MUST have been decorated with
+            `@torch.jit.compile`.
+        args (tuple or Tensor): the positional arguments to pass to the
+            compiled function/module to be verified.  A non-tuple is assumed to
+            be a single positional argument to be passed to the model.
+        loss_fn (function, optional): the loss function to be applied to
+            the output of the model, before backwards is invoked.  By default,
+            we assume that a model returns a single result, and we :func:`torch.sum`
+            before calling backwards; if this is inappropriate, you can pass your
+            own loss function.  Note that if a model returns a tuple of results,
+            these are passed as separate positional arguments to `loss_fn`.
+        devices (iterable of device IDs, optional): the GPU devices which the
+            compiled module will be run on.  This determines the RNG state we
+            must save when running both compiled and uncompiled versions of the model.

+    :class:`ScriptFunction` or :class:`ScriptModule`. You must provide example
+    inputs, and we run the function, recording the operations performed on all
+    the tensors.
+
+    * The resulting recording of a standalone function produces `ScriptFunction`.
+    * The resulting recording of `nn.Module.forward` or `nn.Module` produces
+      `ScriptModule`.
+
+    This module also contains any parameters that the original
+    module had as well.
+
+    Warning:
+        Tracing only correctly records functions and modules which are not data
+        dependent (e.g., do not have conditionals on data in tensors) and do not have
+        any untracked external dependencies (e.g., perform input/output or
+        access global variables). Tracing only records operations done when the given
+        function is run on the given tensors. Therefore, the returned
+        `ScriptModule` will always run the same traced graph on any input. This
+        has some important implications when your module is expected to run
+        different sets of operations, depending on the input and/or the module
+        state. For example,
+
+        * Tracing will not record any control-flow like if-statements or loops.
+          When this control-flow is constant across your module, this is fine
+          and it often inlines the control-flow decisions. But sometimes the
+          control-flow is actually part of the model itself. For instance, a
+          recurrent network is a loop over the (possibly dynamic) length of an
+          input sequence.
+        * In the returned :class:`ScriptModule`, operations that have different
+          behaviors in ``training`` and ``eval`` modes will always behave as if
+          it is in the mode it was in during tracing, no matter which mode the
+          `ScriptModule` is in.
+
+        In cases like these, tracing would not be appropriate and
+        :func:`scripting <torch.jit.script>` is a better choice. If you trace
+        such models, you may silently get incorrect results on subsequent
+        invocations of the model. The tracer will try to emit warnings when
+        doing something that may cause an incorrect trace to be produced.
+
+    Args:
+        func (callable or torch.nn.Module):  A Python function or `torch.nn.Module`
+            that will be run with `example_inputs`. `func` arguments and return
+            values  must be tensors or (possibly nested) tuples that contain
+            tensors. When a module is passed `torch.jit.trace`, only the
+            ``forward`` method is run and traced (see :func:`torch.jit.trace
+            <torch.jit.trace_module>` for details).
+
+    Keyword arguments:
+        example_inputs (tuple or torch.Tensor or None, optional): A tuple of example
+            inputs that will be passed to the function while tracing.
+            Default: ``None``. Either this argument or ``example_kwarg_inputs``
+            should be specified. The resulting trace can be run with inputs of
+            different types and shapes assuming the traced operations support those
+            types and shapes. `example_inputs` may also be a single Tensor in which
+            case it is automatically wrapped in a tuple. When the value is None,
+            ``example_kwarg_inputs`` should be specified.
+
+        check_trace (``bool``, optional): Check if the same inputs run through
+            traced code produce the same outputs. Default: ``True``. You might want
+            to disable this if, for example, your network contains non-
+            deterministic ops or if you are sure that the network is correct despite
+            a checker failure.
+
+        check_inputs (list of tuples, optional): A list of tuples of input
+            arguments that should be used to check the trace against what is
+            expected. Each tuple is equivalent to a set of input arguments that
+            would be specified in ``example_inputs``. For best results, pass in
+            a set of checking inputs representative of the space of shapes and
+            types of inputs you expect the network to see.  If not specified,
+            the original ``example_inputs`` are used for checking
+        check_tolerance (float, optional): Floating-point comparison tolerance
+            to use in the checker procedure.  This can be used to relax the
+            checker strictness in the event that results diverge numerically
+            for a known reason, such as operator fusion.
+        strict (``bool``, optional): run the tracer in a strict mode or not
+            (default: ``True``). Only turn this off when you want the tracer to
+            record your mutable container types (currently ``list``/``dict``)
+            and you are sure that the container you are using in your
+            problem is a ``constant`` structure and does not get used as
+            control flow (if, for) conditions.
+        example_kwarg_inputs (dict, optional): This parameter is a pack of keyword
+            arguments of example inputs that will be passed to the function while
+            tracing. Default: ``None``. Either this argument or ``example_inputs``
+            should be specified. The dict will be unpacking by the arguments name
+            of the traced function. If the keys of the dict don't not match with
+            the traced function's arguments name, a runtime exception will be raised.
+
+    Returns:
+        If `func` is `nn.Module` or ``forward`` of `nn.Module`, `trace` returns
+        a :class:`ScriptModule` object with a single ``forward`` method
+        containing the traced code.  The returned `ScriptModule` will
+        have the same set of sub-modules and parameters as the original
+        ``nn.Module``.  If ``func`` is a standalone function, ``trace``
+        returns `ScriptFunction`.
+
+    Example (tracing a function):

+        def foo(x, y):

+        traced_foo = torch.jit.trace(foo, (torch.rand(3), torch.rand(3)))

+linalg.cholesky_ex(A, *, upper=False, check_errors=False, out=None) -> (Tensor, Tensor)
+
+Computes the Cholesky decomposition of a complex Hermitian or real
+symmetric positive-definite matrix.
+
+This function skips the (slow) error checking and error message construction
+of :func:`torch.linalg.cholesky`, instead directly returning the LAPACK
+error codes as part of a named tuple ``(L, info)``. This makes this function
+a faster way to check if a matrix is positive-definite, and it provides an
+opportunity to handle decomposition errors more gracefully or performantly
+than :func:`torch.linalg.cholesky` does.
+
+Supports input of float, double, cfloat and cdouble dtypes.
+Also supports batches of matrices, and if :attr:`A` is a batch of matrices then
+the output has the same batch dimensions.
+
+If :attr:`A` is not a Hermitian positive-definite matrix, or if it's a batch of matrices
+and one or more of them is not a Hermitian positive-definite matrix,
+then ``info`` stores a positive integer for the corresponding matrix.

+    A named tuple `(eigenvalues, eigenvectors)` which corresponds to :math:`\Lambda` and :math:`Q` above.
+
+    `eigenvalues` will always be real-valued, even when :attr:`A` is complex.

+the **full SVD** of a matrix
+:math:`A \in \mathbb{K}^{m \times n}`, if `k = min(m,n)`, is defined as

+    \mathrlap{\qquad U \in \mathbb{K}^{m \times m}, S \in \mathbb{R}^k, V \in \mathbb{K}^{n \times n}}
+
+where :math:`\operatorname{diag}(S) \in \mathbb{K}^{m \times n}`,
+:math:`V^{\text{H}}` is the conjugate transpose when :math:`V` is complex, and the transpose when :math:`V` is real-valued.
+The matrices  :math:`U`, :math:`V` (and thus :math:`V^{\text{H}}`) are orthogonal in the real case, and unitary in the complex case.
+
+When `m > n` (resp. `m < n`) we can drop the last `m - n` (resp. `n - m`) columns of `U` (resp. `V`) to form the **reduced SVD**:
+
+.. math::

+where :math:`\operatorname{diag}(S) \in \mathbb{K}^{k \times k}`.
+In this case, :math:`U` and :math:`V` also have orthonormal columns.
+
+Supports input of float, double, cfloat and cdouble dtypes.
+Also supports batches of matrices, and if :attr:`A` is a batch of matrices then
+the output has the same batch dimensions.
+
+The returned decomposition is a named tuple `(U, S, Vh)`
+which corresponds to :math:`U`, :math:`S`, :math:`V^{\text{H}}` above.
+
+The singular values are returned in descending order.
+
+The parameter :attr:`full_matrices` chooses between the full (default) and reduced SVD.
+
+The :attr:`driver` kwarg may be used in CUDA with a cuSOLVER backend to choose the algorithm used to compute the SVD.
+The choice of a driver is a trade-off between accuracy and speed.
+
+- If :attr:`A` is well-conditioned (its `condition number`_ is not too large), or you do not mind some precision loss.
+
+  - For a general matrix: `'gesvdj'` (Jacobi method)
+  - If :attr:`A` is tall or wide (`m >> n` or `m << n`): `'gesvda'` (Approximate method)
+
+- If :attr:`A` is not well-conditioned or precision is relevant: `'gesvd'` (QR based)
+
+By default (:attr:`driver`\ `= None`), we call `'gesvdj'` and, if it fails, we fallback to `'gesvd'`.
+
+Differences with `numpy.linalg.svd`:
+
+- Unlike `numpy.linalg.svd`, this function always returns a tuple of three tensors
+  and it doesn't support `compute_uv` argument.
+  Please use :func:`torch.linalg.svdvals`, which computes only the singular values,
+  instead of `compute_uv=False`.
+
+.. note:: When :attr:`full_matrices`\ `= True`, the gradients with respect to `U[..., :, min(m, n):]`
+          and `Vh[..., min(m, n):, :]` will be ignored, as those vectors can be arbitrary bases
+          of the corresponding subspaces.
+
+.. warning:: The returned tensors `U` and `V` are not unique, nor are they continuous with
+             respect to :attr:`A`.
+             Due to this lack of uniqueness, different hardware and software may compute
+             different singular vectors.
+
+             This non-uniqueness is caused by the fact that multiplying any pair of singular
+             vectors :math:`u_k, v_k` by `-1` in the real case or by
+             :math:`e^{i \phi}, \phi \in \mathbb{R}` in the complex case produces another two
+             valid singular vectors of the matrix.
+             For this reason, the loss function shall not depend on this :math:`e^{i \phi}` quantity,
+             as it is not well-defined.
+             This is checked for complex inputs when computing the gradients of this function. As such,
+             when inputs are complex and are on a CUDA device, the computation of the gradients
+             of this function synchronizes that device with the CPU.
+
+.. warning:: Gradients computed using `U` or `Vh` will only be finite when
+             :attr:`A` does not have repeated singular values. If :attr:`A` is rectangular,
+             additionally, zero must also not be one of its singular values.
+             Furthermore, if the distance between any two singular values is close to zero,
+             the gradient will be numerically unstable, as it depends on the singular values

+the **LU decomposition with partial pivoting** of a matrix

+    A = PLU\mathrlap{\qquad P \in \mathbb{K}^{m \times m}, L \in \mathbb{K}^{m \times k}, U \in \mathbb{K}^{k \times n}}
+
+where `k = min(m,n)`, :math:`P` is a `permutation matrix`_, :math:`L` is lower triangular with ones on the diagonal
+and :math:`U` is upper triangular.

+If :attr:`pivot`\ `= False` and :attr:`A` is on GPU, then the **LU decomposition without pivoting** is computed

+
+When :attr:`pivot`\ `= False`, the returned matrix :attr:`P` will be empty.

+        :func:`torch.linalg.solve` solves a system of linear equations using the LU decomposition

+
+.. warning:: The LU decomposition is almost never unique, as often there are different permutation

+             As such, different platforms, like SciPy, or inputs on different devices,

+
+.. warning:: Gradient computations are only supported if the input matrix is full-rank.
+             If this condition is not met, no error will be thrown, but the gradient
+             may not be finite.
+             This is because the LU decomposition with pivoting is not differentiable at these points.

+When `m > n` (tall matrix), as `R` is upper triangular, its last `m - n` rows are zero.

+Returns maximum of all the elements in the :attr:`input`
+tensor along the given dimension(s) :attr:`dim` while the :attr:`input`
+elements are masked out according to the boolean tensor
+:attr:`mask`.
+
+The identity value of maximum operation, which is used to start the
+reduction, depends on input dtype. For instance, for float32, uint8,
+and int32 dtypes, the identity values are ``-inf``, ``0``, and ``-2147483648``, respectively.
+
+If :attr:`keepdim` is ``True``, the output tensor is of the same size
+as :attr:`input` except in the dimension(s) :attr:`dim` where it is of
+size 1. Otherwise, :attr:`dim` is squeezed (see
+:func:`torch.squeeze`), resulting in the output tensor having 1 (or
+``len(dim)``) fewer dimension(s).
+
+The boolean tensor :attr:`mask` defines the "validity" of
+:attr:`input` tensor elements: if :attr:`mask` element is True
+then the corresponding element in :attr:`input` tensor will be
+included in maximum computation, otherwise the element is
+ignored.
+
+When all elements of :attr:`input` along the given dimension
+:attr:`dim` are ignored (fully masked-out), the corresponding element

+tensor along the given dimension(s) :attr:`dim` while the :attr:`input`
+elements are masked out according to the boolean tensor
+:attr:`mask`.
+The identity value of sample variance operation is undefined. The
+elements of output tensor with strided layout, that correspond to
+fully masked-out elements, have ``nan`` values.
+If :attr:`keepdim` is ``True``, the output tensor is of the same size
+as :attr:`input` except in the dimension(s) :attr:`dim` where it is of
+size 1. Otherwise, :attr:`dim` is squeezed (see
+:func:`torch.squeeze`), resulting in the output tensor having 1 (or
+``len(dim)``) fewer dimension(s).
+
+The boolean tensor :attr:`mask` defines the "validity" of
+:attr:`input` tensor elements: if :attr:`mask` element is True
+then the corresponding element in :attr:`input` tensor will be
+included in variance computation, otherwise the element is
+ignored.
+
+When all elements of :attr:`input` along the given dimension
+:attr:`dim` are ignored (fully masked-out), the corresponding element
+of the output tensor will have undefined value: it may or may not
+correspond to the identity value of variance operation; the
+choice may correspond to the value that leads to the most efficient
+storage of :attr:`output` tensor.
+
+The mask of the output tensor can be computed as
+``torch.any(torch.broadcast_to(mask, input.shape), dim, keepdim=keepdim,
+dtype=torch.bool)``.
+
+The shapes of the :attr:`mask` tensor and the :attr:`input` tensor
+don't need to match, but they must be :ref:`broadcastable
+<broadcasting-semantics>` and the dimensionality of the :attr:`mask`
+tensor must not be greater than of the :attr:`input` tensor.
+
+Args:
+    input (Tensor): the input tensor
+    dim (int or tuple of ints, optional): the dimension or dimensions to reduce.
+      Default: None that is equivalent to ``tuple(range(input.ndim))``.
+    unbiased (bool): when True, use Bessel's correction, otherwise, compute
+      the uncorrected sample variance.
+
+Keyword args:
+    keepdim (bool, optional): whether the output tensor has
+      :attr:`dim` retained or not. Default: False.
+    dtype (:class:`torch.dtype`, optional): the desired data type
+      of returned tensor.  If specified, the input tensor is
+      casted to :attr:`dtype` before the operation is
+      performed. Default: None.
+    mask (:class:`torch.Tensor`, optional): the boolean tensor
+      containing the binary mask of validity of input tensor
+      elements.
+      Default: None that is equivalent to ``torch.ones(input.shape, dtype=torch.bool)``.
+Example::
+
+    >>> input = tensor([[-3, -2, -1], [ 0, 1, 2]])
+    >>> input
+    tensor([[-3, -2, -1],
+            [ 0,  1,  2]])

+
+    A canonical input mask is defined as a boolean mask tensor that

+
+    The canonical input mask is computed from the :attr:`mask` tensor
+    content to meet the following criteria:
+
+    1. The shape of the canonical input mask is the same as the shape
+       of :attr:`input` tensor. If the mask tensor has a smaller shape
+       than the shape of the :attr:`input`, broadcasting rules will be
+       applied. Downcasting of mask is not supported.
+
+    2. The layout of the canonical input mask is the same as the
+       layout of the :attr:`input` tensor. If the mask has different
+       layout, it will be converted to the expected layout.  In the
+       case of sparse COO layout, the canonical input mask will be
+       coalesced.
+
+    3. The dtype of the canonical input mask is torch.bool. If the
+       mask dtype is not bool then it will be converted to bool dtype
+       using `.to(dtype=bool)` method call.
+
+    4. The elements of the canonical input mask have boolean values
+       copied from the content of the :attr:`mask` tensor (after
+       possible broadcasting and dtype conversion transforms).  In
+       general, the sparsity pattern of the sparse canonical input
+       mask need not to be the same as the sparsity pattern of the
+       sparse :attr:`input` tensor.

+"""torch.multiprocessing is a wrapper around the native :mod:`multiprocessing` module.
+
+It registers custom reducers, that use shared memory to provide shared
+views on the same data in different processes. Once the tensor/storage is moved
+to shared_memory (see :func:`~torch.Tensor.share_memory_`), it will be possible
+to send it to other processes without making any copies.
+
+The API is 100% compatible with the original module - it's enough to change
+``import multiprocessing`` to ``import torch.multiprocessing`` to have all the
+tensors sent through the queues or shared via other mechanisms, moved to shared
+memory.
+
+Because of the similarity of APIs we do not document most of this package
+contents, and we recommend referring to very good docs of the original module.

+    # might be part of a larger cudaMalloc allocation 0xA000 of size 0x4000.
+    #
+    # When we want to send this CUDA tensor over IPC, we must send the
+    # *entire* cudaMalloc allocation, i.e., the 0xA000 region, not just
+    # the storage 0xA100 (because that is what CUDA supports).  So, on the
+    # other end, there simply isn't any way to say, "Wait, you gave me
+    # a bigger region (0xA000) than the one I wanted (0xA100)".
+    #
+    # OK, so if you sent the cudaMalloc allocation, can you just wrap that up as
+    # one storage itself? No, because this cudaMalloc allocation might contain
+    # storages of mixed types: float, bytes, double... If you make the entire
+    # allocation a single storage of a type A, we'll hit an error when constructing
+    # a tensor of type B on the storage.
+    #
+    # cudaIpcMemHandle is an identifier to access the sender cudaMalloc allocation on the
+    # receiver side. However, cudaIpcMemHandles from each device in a given process may
+    # only be opened by one context per device per other process.
+    # If we open and close a memory handle multiples times in a process, CUDA is allowed
+    # to give it a different address; similarly, once we close the memory, we're not
+    # allowed to access it(and the storage/tensor built on top of it), even if it is
+    # still live in the original process. As we cannot make a cudaMalloc allocation
+    # to a single storage in one go, this requires us to cache the device pointer for
+    # each cudaIpcMemHandle on C++ side to reconstruct types of storages, while keep
+    # the old ones alives.
+    # See [https://docs.nvidia.com/cuda/cuda-runtime-api/group__CUDART__DEVICE.html]
+    #
+    # This is fine, because all we need to do is to save our position in the allocation,
+    # and reconstruct storage and tensor from it.

+    # 0xE000 ->  --------CUDA allocation-----
+    #
+    # To send tensor1, the following info are required from sender to receiver for
+    # storage reconstruction.
+    #   1. cudaIpcMemHandle of 0xA000(which can be mapped to a basePtr in receiver process).
+    #      basePtr may not be exactly 0xA000 since it's a different process.
+    #   2. offset(0xA100) of storage1 in the CUDA allocation.
+    #   3. size of storage1(0x100).
+    #
+    # On receiver side:
+    #   1. Get the devPtr of the MemHandle to access the memory, reconstruct a storage
+    #      of the same type using (basePtr, offset, size).
+    #   2. we can reconstruct the tensor on top of the reconstructed storage
+    #   Tensor(size=0x040, offset=0x020, storage=Storage(data=basePtr+0xA100, size=0x0100))
+    #
+    # This strategy has a few implications:
+    #
+    # 1. When we serialize a CUDA tensor for IPC, we cannot do it all in one
+    #    go (non-compositionally), and this requires to have a global map
+    #    memHandle -> devPtr for each process.
+    #
+    # 2. We MUST NOT let the new IPC tensor be resizable.  Originally, a resize
+    #    of the storage beyond 0x100 would merely have caused us to do a
+    #    reallocation.  You don't really want to do this, but if you did,
+    #    all that would happen is that you would lose IPC sharing.  But if
+    #    you do this in the new world, we will happily let you write out of
+    #    bounds of your "allocation", clobbering unrelated data in the cached
+    #    allocator block.  BAD!
+    #
+    # By the way, in old versions of PyTorch, we supported this situation
+    # natively using a "storage view", which permitted multiple storages to be
+    # views on each other.  But this was the *only* use of storage views, so we
+    # eliminated it so that we could just use tensor views to implement the same
+    # thing.

+        offsets (optional :class:`torch.Tensor`): Offsets into the jagged dimension of shape B + 1.
+        lengths (optional :class:`torch.Tensor`): Lengths of the batch elements of shape B.
+        jagged_dim (optional int): Indicates which dimension in values is the packed jagged
+            dimension. Must be >= 1 as the batch dimension (dim=0) cannot be ragged.
+            If None, this is set to dim=1 (i.e. the dimension immediately following the batch dimension). Default: None
+        min_seqlen (optional int): If set, uses the specified value as the cached minimum sequence
+            length for the returned nested tensor. This can be a useful alternative to computing

+    [Autocasting SDPA for NJT]
+
+    Normal autocasting doesn't work for NJT+SDPA right now:
+    * NJT intercepts the __torch_function__ call for scaled_dot_product_attention, which happens
+      before we get to any aten ops or dispatcher logic; then the torch_function logic calls into
+      efficient attention or flash attention. So, autocasting on the scaled_dot_product_attention
+      op won't work because we never see that aten op.
+    * If we put autocasting on `_flash_attention_forward`, then we'll get autocasting to run, but
+      the kernel selection logic in torch_function handling (ie. jagged_scaled_dot_product_attention)
+      won't work correctly: the kernel selection logic will run before autocasting, and choose
+      a kernel based on the un-autocasted dtypes; but then autocasting will run and the actual
+      attention computation will happen in a different dtype.
+
+    An alternative is to just change the backend selection logic for SDPA+NJT to be autocast-aware
+    and rely on autocasting to do the actual conversions for flash attention / efficient attention.
+    However, by manually doing the actual autocast before the backend selection, we ensure that the
+    autocast handling for backend selection doesn't diverge from the autocast handling for the
+    actual dtype conversions.

+
+    The options can be prefixed with ``fwd_`` or ``bwd_`` to apply only to forward or

+class BlockMask:
+    r"""
+    BlockMask is our format for representing a block-sparse attention mask.
+    It is somewhat of a cross in-between BCSR and a non-sparse format.
+
+    **Basics**
+
+    A block-sparse mask means that instead of representing the sparsity of
+    individual elements in the mask, a KV_BLOCK_SIZE x Q_BLOCK_SIZE block is
+    considered sparse only if every element within that block is sparse.
+    This aligns well with hardware, which generally expects to perform
+    contiguous loads and computation.
+
+    This format is primarily optimized for 1. simplicity, and 2. kernel
+    efficiency. Notably, it is *not* optimized for size, as this mask is always
+    reduced by a factor of KV_BLOCK_SIZE * Q_BLOCK_SIZE. If the size is a
+    concern, the tensors can be reduced in size by increasing the block size.
+
+    The essentials of our format are:
+
+    num_blocks_in_row: Tensor[ROWS]:
+    Describes the number of blocks present in each row.
+
+    col_indices: Tensor[ROWS, MAX_BLOCKS_IN_COL]:
+    `col_indices[i]` is the sequence of block positions for row i. The values of
+    this row after `col_indices[i][num_blocks_in_row[i]]` are undefined.
+
+    For example, to reconstruct the original tensor from this format:
+
+    .. code-block:: python
+
+        dense_mask = torch.zeros(ROWS, COLS)
+        for row in range(ROWS):
+            for block_idx in range(num_blocks_in_row[row]):
+                dense_mask[row, col_indices[row, block_idx]] = 1
+
+    Notably, this format makes it easier to implement a reduction along the
+    *rows* of the mask.
+
+    **Details**
+
+    The basics of our format require only kv_num_blocks and kv_indices. But, we
+    have up to 8 tensors on this object. This represents 4 pairs:
+
+    1. (kv_num_blocks, kv_indices): Used for the forwards pass of attention, as
+    we reduce along the KV dimension.
+
+    2. [OPTIONAL] (full_kv_num_blocks, full_kv_indices): This is optional and
+    purely an optimization. As it turns out, applying masking to every block
+    is quite expensive! If we specifically know which blocks are "full" and
+    don't require masking at all, then we can skip applying mask_mod to these
+    blocks. This requires the user to split out a separate mask_mod from the
+    score_mod. For causal masks, this is about a 15% speedup.
+
+    3. [GENERATED] (q_num_blocks, q_indices): Required for the backwards pass,
+    as computing dKV requires iterating along the mask along the Q dimension. These are autogenerated from 1.
+
+    4. [GENERATED] (full_q_num_blocks, full_q_indices): Same as above, but for
+    the backwards pass. These are autogenerated from 2.

+
+    This function computes the scaled dot product attention between query, key, and value tensors with a user-defined
+    attention score modification function. The attention score modification function will be applied after the attention
+    scores have been calculated between the query and key tensors. The attention scores are calculated as follows:
+
+    The ``score_mod`` function should have the following signature:
+
+    .. code-block:: python
+
+        def score_mod(

+            q_idx: Tensor,
+            k_idx: Tensor
+        ) -> Tensor:
+
+    Where:
+        - ``score``: A scalar tensor representing the attention score,
+          with the same data type and device as the query, key, and value tensors.
+        - ``batch``, ``head``, ``q_idx``, ``k_idx``: Scalar tensors indicating
+          the batch index, query head index, query index, and key/value index, respectively.
+          These should have the ``torch.int`` data type and be located on the same device as the score tensor.
+
+    Args:
+        query (Tensor): Query tensor; shape :math:`(B, Hq, L, E)`. For FP8 dtypes, should be in row-major memory layout for optimal performance.
+        key (Tensor): Key tensor; shape :math:`(B, Hkv, S, E)`. For FP8 dtypes, should be in row-major memory layout for optimal performance.
+        value (Tensor): Value tensor; shape :math:`(B, Hkv, S, Ev)`. For FP8 dtypes, should be in column-major memory layout for optimal performance.
+        score_mod (Optional[Callable]): Function to modify attention scores. By default no score_mod is applied.
+        block_mask (Optional[BlockMask]): BlockMask object that controls the blocksparsity pattern of the attention.
+        scale (Optional[float]): Scaling factor applied prior to softmax. If none, the default value is set to :math:`\frac{1}{\sqrt{E}}`.
+        enable_gqa (bool): If set to True, enables Grouped Query Attention (GQA) and broadcasts key/value heads to query heads.
+        return_lse (bool): Whether to return the logsumexp of the attention scores. Default is False. **Deprecated**: Use ``return_aux=AuxRequest(lse=True)`` instead.
+        kernel_options (Optional[FlexKernelOptions]):
+            Options to control the behavior of the underlying Triton kernels.
+            See :class:`FlexKernelOptions` for available options and usage examples.
+        return_aux (Optional[AuxRequest]): Specifies which auxiliary outputs to compute and return.
+            If None, only the attention output is returned. Use ``AuxRequest(lse=True, max_scores=True)``
+            to request both auxiliary outputs.
+
+    Returns:
+        output (Tensor): Attention output; shape :math:`(B, Hq, L, Ev)`.
+
+        When ``return_aux`` is not None:
+            aux (AuxOutput): Auxiliary outputs with requested fields populated.
+
+        When ``return_aux`` is None (deprecated paths):
+            lse (Tensor): Log-sum-exp of attention scores; shape :math:`(B, Hq, L)`. Only returned if ``return_lse=True``.

+
+    Applies 3D fractional max pooling over an input signal composed of several input planes.
+
+    Fractional MaxPooling is described in detail in the paper `Fractional MaxPooling`_ by Ben Graham
+
+    The max-pooling operation is applied in :math:`kT \times kH \times kW` regions by a stochastic
+    step size determined by the target output size.
+    The number of output features is equal to the number of input planes.
+
+    Args:
+        kernel_size: the size of the window to take a max over.
+                     Can be a single number :math:`k` (for a square kernel of :math:`k \times k \times k`)
+                     or a tuple `(kT, kH, kW)`
+        output_size: the target output size of the form :math:`oT \times oH \times oW`.
+                     Can be a tuple `(oT, oH, oW)` or a single number :math:`oH` for a cubic output
+                     :math:`oH \times oH \times oH`
+        output_ratio: If one wants to have an output size as a ratio of the input size, this option can be given.
+                      This has to be a number or tuple in the range (0, 1)
+        return_indices: if ``True``, will return the indices along with the outputs.

+
+    Note:
+        {backward_reproducibility_note}
+
+    Args:
+        input (LongTensor): Tensor containing bags of indices into the embedding matrix
+        weight (Tensor): The embedding matrix with number of rows equal to the maximum possible index + 1,
+            and number of columns equal to the embedding size
+        offsets (LongTensor, optional): Only used when :attr:`input` is 1D. :attr:`offsets` determines
+                             the starting index position of each bag (sequence) in :attr:`input`.
+        max_norm (float, optional): If given, each embedding vector with norm larger than :attr:`max_norm`
+                                    is renormalized to have norm :attr:`max_norm`.
+                                    Note: this will modify :attr:`weight` in-place.
+        norm_type (float, optional): The ``p`` in the ``p``-norm to compute for the :attr:`max_norm` option.
+                                     Default ``2``.
+        scale_grad_by_freq (bool, optional): if given, this will scale gradients by the inverse of frequency of
+                                                the words in the mini-batch. Default ``False``.
+                                                Note: this option is not supported when ``mode="max"``.
+        mode (str, optional): ``"sum"``, ``"mean"`` or ``"max"``. Specifies the way to reduce the bag.
+                                 Default: ``"mean"``
+        sparse (bool, optional): if ``True``, gradient w.r.t. :attr:`weight` will be a sparse tensor. See Notes under
+                                 :class:`torch.nn.Embedding` for more details regarding sparse gradients.
+                                 Note: this option is not supported when ``mode="max"``.
+        per_sample_weights (Tensor, optional): a tensor of float / double weights, or None
+            to indicate all weights should be taken to be 1. If specified, :attr:`per_sample_weights`
+            must have exactly the same shape as input and is treated as having the same
+            :attr:`offsets`, if those are not None.
+
+        include_last_offset (bool, optional): if ``True``, the size of offsets is equal to the number of bags + 1.
+                                              The last element is the size of the input, or the ending index position
+                                              of the last bag (sequence). This matches the CSR format. Ignored when
+                                              input is 2D. Default ``False``.
+
+        padding_idx (int, optional): If specified, the entries at :attr:`padding_idx` do not contribute to the
+                                     gradient; therefore, the embedding vector at :attr:`padding_idx` is not updated
+                                     during training, i.e. it remains as a fixed "pad". Note that the embedding
+                                     vector at :attr:`padding_idx` is excluded from the reduction.
+
+    Shape:
+        - :attr:`input` (LongTensor) and :attr:`offsets` (LongTensor, optional)
+
+          - If :attr:`input` is 2D of shape `(B, N)`, it will be treated as ``B`` bags (sequences)
+            each of fixed length ``N``, and this will return ``B`` values aggregated in a way
+            depending on the :attr:`mode`. :attr:`offsets` is ignored and required to be ``None`` in this case.
+
+          - If :attr:`input` is 1D of shape `(N)`, it will be treated as a concatenation of
+            multiple bags (sequences). :attr:`offsets` is required to be a 1D tensor containing
+            the starting index positions of each bag in :attr:`input`. Therefore, for :attr:`offsets`
+            of shape `(B)`, :attr:`input` will be viewed as having ``B`` bags.
+            Empty bags (i.e., having 0-length) will have returned vectors filled by zeros.
+
+        - :attr:`weight` (Tensor): the learnable weights of the module of shape `(num_embeddings, embedding_dim)`
+
+        - :attr:`per_sample_weights` (Tensor, optional). Has the same shape as :attr:`input`.
+
+        - :attr:`output`: aggregated embedding values of shape `(B, embedding_dim)`

+        if you want to reduce the overshoot when displaying the image.
+        For ``uint8`` inputs, it already performs saturating cast operation. So, no manual `clamp` operation is needed.
+
+    .. note::
+        Mode ``mode='nearest-exact'`` matches Scikit-Image and PIL nearest neighbours interpolation
+        algorithms and fixes known issues with ``mode='nearest'``. This mode is introduced to keep

+
+    Given an :attr:`input` and a flow-field :attr:`grid`, computes the
+    ``output`` using :attr:`input` values and pixel locations from :attr:`grid`.
+
+    Currently, only spatial (4-D) and volumetric (5-D) :attr:`input` are
+    supported.
+
+    In the spatial (4-D) case, for :attr:`input` with shape
+    :math:`(N, C, H_\text{in}, W_\text{in})` and :attr:`grid` with shape
+    :math:`(N, H_\text{out}, W_\text{out}, 2)`, the output will have shape
+    :math:`(N, C, H_\text{out}, W_\text{out})`.
+
+    For each output location ``output[n, :, h, w]``, the size-2 vector
+    ``grid[n, h, w]`` specifies :attr:`input` pixel locations ``x`` and ``y``,
+    which are used to interpolate the output value ``output[n, :, h, w]``.
+    In the case of 5D inputs, ``grid[n, d, h, w]`` specifies the
+    ``x``, ``y``, ``z`` pixel locations for interpolating
+    ``output[n, :, d, h, w]``. :attr:`mode` argument specifies ``nearest`` or
+    ``bilinear`` interpolation method to sample the input pixels.
+
+    :attr:`grid` specifies the sampling pixel locations normalized by the
+    :attr:`input` spatial dimensions. Therefore, it should have most values in
+    the range of ``[-1, 1]``. For example, values ``x = -1, y = -1`` is the
+    left-top pixel of :attr:`input`, and values  ``x = 1, y = 1`` is the
+    right-bottom pixel of :attr:`input`.
+
+    If :attr:`grid` has values outside the range of ``[-1, 1]``, the corresponding
+    outputs are handled as defined by :attr:`padding_mode`. Options are
+
+        * ``padding_mode="zeros"``: use ``0`` for out-of-bound grid locations,
+        * ``padding_mode="border"``: use border values for out-of-bound grid locations,
+        * ``padding_mode="reflection"``: use values at locations reflected by
+          the border for out-of-bound grid locations. For location far away
+          from the border, it will keep being reflected until becoming in bound,
+          e.g., (normalized) pixel location ``x = -3.5`` reflects by border ``-1``
+          and becomes ``x' = 1.5``, then reflects by border ``1`` and becomes
+          ``x'' = -0.5``.
+
+    Note:
+        This function is often used in conjunction with :func:`affine_grid`
+        to build `Spatial Transformer Networks`_ .
+
+    Note:
+        When using the CUDA backend, this operation may induce nondeterministic
+        behaviour in its backward pass that is not easily switched off.
+        Please see the notes on :doc:`/notes/randomness` for background.
+
+    Note:
+        NaN values in :attr:`grid` would be interpreted as ``-1``.
+
+    Args:
+        input (Tensor): input of shape :math:`(N, C, H_\text{in}, W_\text{in})` (4-D case)
+                        or :math:`(N, C, D_\text{in}, H_\text{in}, W_\text{in})` (5-D case)
+        grid (Tensor): flow-field of shape :math:`(N, H_\text{out}, W_\text{out}, 2)` (4-D case)
+                       or :math:`(N, D_\text{out}, H_\text{out}, W_\text{out}, 3)` (5-D case)
+        mode (str): interpolation mode to calculate output values
+            ``'bilinear'`` | ``'nearest'`` | ``'bicubic'``. Default: ``'bilinear'``
+            Note: ``mode='bicubic'`` supports only 4-D input.
+            When ``mode='bilinear'`` and the input is 5-D, the interpolation mode
+            used internally will actually be trilinear. However, when the input is 4-D,
+            the interpolation mode will legitimately be bilinear.
+        padding_mode (str): padding mode for outside grid values
+            ``'zeros'`` | ``'border'`` | ``'reflection'``. Default: ``'zeros'``
+        align_corners (bool, optional): Geometrically, we consider the pixels of the
+            input  as squares rather than points.
+            If set to ``True``, the extrema (``-1`` and ``1``) are considered as referring
+            to the center points of the input's corner pixels. If set to ``False``, they
+            are instead considered as referring to the corner points of the input's corner
+            pixels, making the sampling more resolution agnostic.
+            This option parallels the ``align_corners`` option in
+            :func:`interpolate`, and so whichever option is used here
+            should also be used there to resize the input image before grid sampling.
+            Default: ``False``
+
+    Returns:
+        output (Tensor): output Tensor

+
+    .. warning::
+        When ``align_corners = True``, the grid positions depend on the pixel
+        size relative to the input image size, and so the locations sampled by
+        :func:`grid_sample` will differ for the same input given at different
+        resolutions (that is, after being upsampled or downsampled).
+        The default behavior up to version 1.2.0 was ``align_corners = True``.
+        Since then, the default behavior has been changed to ``align_corners = False``,
+        in order to bring it in line with the default for :func:`interpolate`.
+
+    .. note::
+        ``mode='bicubic'`` is implemented using the `cubic convolution algorithm`_ with :math:`\alpha=-0.75`.
+        The constant :math:`\alpha` might be different from packages to packages.
+        For example, `PIL`_ and `OpenCV`_ use -0.5 and -0.75 respectively.
+        This algorithm may "overshoot" the range of values it's interpolating.
+        For example, it may produce negative values or values greater than 255 when interpolating input in [0, 255].
+        Clamp the results with :func:`torch.clamp` to ensure they are within the valid range.

+
+        There are currently three supported implementations of scaled dot product attention:
+

+            - `Memory-Efficient Attention`_
+            - A PyTorch implementation defined in C++ matching the above formulation
+
+        The function may call optimized kernels for improved performance when using the CUDA backend.
+        For all other backends, the PyTorch implementation will be used.
+
+        All implementations are enabled by default. Scaled dot product attention attempts to automatically select the
+        most optimal implementation based on the inputs. In order to provide more fine-grained control over what implementation
+        is used, the following functions are provided for enabling and disabling implementations.
+        The context manager is the preferred mechanism:
+
+            - :func:`torch.nn.attention.sdpa_kernel`: A context manager used to enable or disable any of the implementations.
+            - :func:`torch.backends.cuda.enable_flash_sdp`: Globally enables or disables FlashAttention.
+            - :func:`torch.backends.cuda.enable_mem_efficient_sdp`: Globally enables or disables  Memory-Efficient Attention.
+            - :func:`torch.backends.cuda.enable_math_sdp`: Globally enables or disables  the PyTorch C++ implementation.
+
+        Each of the fused kernels has specific input limitations. If the user requires the use of a specific fused implementation,
+        disable the PyTorch C++ implementation using :func:`torch.nn.attention.sdpa_kernel`.
+        In the event that a fused implementation is not available, a warning will be raised with the
+        reasons why the fused implementation cannot run.
+
+        Due to the nature of fusing floating point operations, the output of this function may be different
+        depending on what backend kernel is chosen.
+        The c++ implementation supports torch.float64 and can be used when higher precision is required.
+        For math backend, all intermediates are kept in torch.float if inputs are in torch.half or torch.bfloat16.
+    For more information please see :doc:`/notes/numerical_accuracy`

+
+    See :class:`torch.nn.MultiheadAttention` for details.
+
+    Args:
+        query, key, value: map a query and a set of key-value pairs to an output.
+            See "Attention Is All You Need" for more details.
+        embed_dim_to_check: total dimension of the model.
+        num_heads: parallel attention heads.
+        in_proj_weight, in_proj_bias: input projection weight and bias.
+        bias_k, bias_v: bias of the key and value sequences to be added at dim=0.
+        add_zero_attn: add a new batch of zeros to the key and
+                       value sequences at dim=1.
+        dropout_p: probability of an element to be zeroed.
+        out_proj_weight, out_proj_bias: the output projection weight and bias.
+        training: apply dropout if is ``True``.
+        key_padding_mask: if provided, specified padding elements in the key will
+            be ignored by the attention. This is an binary mask. When the value is True,
+            the corresponding value on the attention layer will be filled with -inf.
+        need_weights: output attn_output_weights.
+            Default: `True`
+            Note: `needs_weight` defaults to `True`, but should be set to `False`
+            For best performance when attention weights are not needed.
+            *Setting needs_weights to `True`
+            leads to a significant performance degradation.*
+        attn_mask: 2D or 3D mask that prevents attention to certain positions. A 2D mask will be broadcasted for all
+            the batches while a 3D mask allows to specify a different mask for the entries of each batch.
+        is_causal: If specified, applies a causal mask as attention mask, and ignores
+            attn_mask for computing scaled dot product attention.
+            Default: ``False``.
+            .. warning::
+                is_causal is provides a hint that the attn_mask is the
+                causal mask.Providing incorrect hints can result in
+                incorrect execution, including forward and backward
+                compatibility.
+        use_separate_proj_weight: the function accept the proj. weights for query, key,
+            and value in different forms. If false, in_proj_weight will be used, which is
+            a combination of q_proj_weight, k_proj_weight, v_proj_weight.
+        q_proj_weight, k_proj_weight, v_proj_weight, in_proj_bias: input projection weight and bias.
+        static_k, static_v: static key and value used for attention operators.
+        average_attn_weights: If true, indicates that the returned ``attn_weights`` should be averaged across heads.
+            Otherwise, ``attn_weights`` are provided separately per head. Note that this flag only has an effect
+            when ``need_weights=True.``. Default: True

+          the embedding dimension.
+        - key: :math:`(S, E)` or :math:`(S, N, E)`, where S is the source sequence length, N is the batch size, E is
+          the embedding dimension.
+        - value: :math:`(S, E)` or :math:`(S, N, E)` where S is the source sequence length, N is the batch size, E is
+          the embedding dimension.
+        - key_padding_mask: :math:`(S)` or :math:`(N, S)` where N is the batch size, S is the source sequence length.
+          If a FloatTensor is provided, it will be directly added to the value.
+          If a BoolTensor is provided, the positions with the
+          value of ``True`` will be ignored while the position with the value of ``False`` will be unchanged.
+        - attn_mask: 2D mask :math:`(L, S)` where L is the target sequence length, S is the source sequence length.
+          3D mask :math:`(N*num_heads, L, S)` where N is the batch size, L is the target sequence length,
+          S is the source sequence length. attn_mask ensures that position i is allowed to attend the unmasked
+          positions. If a BoolTensor is provided, positions with ``True``
+          are not allowed to attend while ``False`` values will be unchanged. If a FloatTensor
+          is provided, it will be added to the attention weight.
+        - static_k: :math:`(N*num_heads, S, E/num_heads)`, where S is the source sequence length,
+          N is the batch size, E is the embedding dimension. E/num_heads is the head dimension.
+        - static_v: :math:`(N*num_heads, S, E/num_heads)`, where S is the source sequence length,
+          N is the batch size, E is the embedding dimension. E/num_heads is the head dimension.
+
+        Outputs:
+        - attn_output: :math:`(L, E)` or :math:`(L, N, E)` where L is the target sequence length, N is the batch size,
+          E is the embedding dimension.
+        - attn_output_weights: Only returned when ``need_weights=True``. If ``average_attn_weights=True``, returns
+          attention weights averaged across heads of shape :math:`(L, S)` when input is unbatched or
+          :math:`(N, L, S)`, where :math:`N` is the batch size, :math:`L` is the target sequence length, and
+          :math:`S` is the source sequence length. If ``average_attn_weights=False``, returns attention weights per
+          head of shape :math:`(num_heads, L, S)` when input is unbatched or :math:`(N, num_heads, L, S)`.

+
+    Computes a grouped matrix multiply that shares weight shapes across experts but
+    allows jagged token counts per expert, which is common in Mixture-of-Experts
+    (MoE) layers. Both ``mat_a`` and ``mat_b`` must be 2D or 3D tensors that already
+    satisfy the physical layout restrictions of grouped GEMM kernels (e.g., row-major
+    ``mat_a`` and column-major ``mat_b`` for FP8 inputs). Inputs are currently
+    expected to be ``torch.bfloat16`` values on CUDA devices with :math:`SM \ge 80`.
+
+    Args:
+        mat_a: Left operand. When 2D, its leading dimension is sliced into groups
+            according to ``offs``. When 3D, its first dimension enumerates the groups
+            directly and ``offs`` must be ``None``.
+        mat_b: Right operand. When both operands are 2D (e.g., MoE weight-gradient
+            updates), the trailing dimension of ``mat_a`` and the leading dimension of
+            ``mat_b`` are partitioned according to the same ``offs`` tensor. For the
+            common forward pass (``out = input @ weight.T``) ``mat_b`` is 3D with
+            shape ``(num_groups, N, K)``.
+        offs: Optional 1D tensor of monotonically increasing ``int32`` offsets that
+            delimit the jagged dimension of any 2D operand. ``offs[i]`` marks the end
+            of group ``i`` and ``offs[-1]`` must be strictly less than the total
+            length of that operand's sliced dimension; elements beyond ``offs[-1]``
+            are ignored.
+        bias: Optional tensor that is added to the grouped outputs. Bias is not
+            jagged and must be broadcastable to the result shape of each group.
+        out_dtype: Optional dtype that controls the accumulation/output dtype.
+            Passing ``torch.float32`` accumulates BF16 inputs in FP32 while keeping
+            the grouped GEMM API non-differentiable.
+
+    Returns:
+        A tensor containing the concatenated results of each per-group GEMM with

+
+    This MultiheadAttention layer implements the original architecture described
+    in the `Attention Is All You Need <https://arxiv.org/abs/1706.03762>`_ paper. The
+    intent of this layer is as a reference implementation for foundational understanding
+    and thus it contains only limited features relative to newer architectures.
+    Given the fast pace of innovation in transformer-like architectures, we recommend
+    exploring this `tutorial <https://pytorch.org/tutorials/intermediate/transformer_building_blocks.html>`_
+    to build efficient layers from building blocks in core or using higher
+    level libraries from the `PyTorch Ecosystem <https://landscape.pytorch.org/>`_.
+
+    Multi-Head Attention is defined as:
+
+    .. math::
+        \text{MultiHead}(Q, K, V) = \text{Concat}(\text{head}_1,\dots,\text{head}_h)W^O
+
+    where :math:`\text{head}_i = \text{Attention}(QW_i^Q, KW_i^K, VW_i^V)`.
+
+    ``nn.MultiheadAttention`` will use the optimized implementations of
+    ``scaled_dot_product_attention()`` when possible.
+
+    In addition to support for the new ``scaled_dot_product_attention()``
+    function, for speeding up Inference, MHA will use
+    fastpath inference with support for Nested Tensors, iff:
+
+    - self attention is being computed (i.e., ``query``, ``key``, and ``value`` are the same tensor).
+    - inputs are batched (3D) with ``batch_first==True``
+    - Either autograd is disabled (using ``torch.inference_mode`` or ``torch.no_grad``) or no tensor argument ``requires_grad``
+    - training is disabled (using ``.eval()``)
+    - ``add_bias_kv`` is ``False``
+    - ``add_zero_attn`` is ``False``
+    - ``kdim`` and ``vdim`` are equal to ``embed_dim``
+    - if a `NestedTensor <https://pytorch.org/docs/stable/nested.html>`_ is passed, neither ``key_padding_mask``
+      nor ``attn_mask`` is passed
+    - autocast is disabled
+
+    If the optimized inference fastpath implementation is in use, a
+    `NestedTensor <https://pytorch.org/docs/stable/nested.html>`_ can be passed for
+    ``query``/``key``/``value`` to represent padding more efficiently than using a
+    padding mask. In this case, a `NestedTensor <https://pytorch.org/docs/stable/nested.html>`_
+    will be returned, and an additional speedup proportional to the fraction of the input
+    that is padding can be expected.
+
+    Args:
+        embed_dim: Total dimension of the model.
+        num_heads: Number of parallel attention heads. Note that ``embed_dim`` will be split
+            across ``num_heads`` (i.e. each head will have dimension ``embed_dim // num_heads``).
+        dropout: Dropout probability on ``attn_output_weights``. Default: ``0.0`` (no dropout).
+        bias: If specified, adds bias to input / output projection layers. Default: ``True``.
+        add_bias_kv: If specified, adds bias to the key and value sequences at dim=0. Default: ``False``.
+        add_zero_attn: If specified, adds a new batch of zeros to the key and value sequences at dim=1.
+            Default: ``False``.
+        kdim: Total number of features for keys. Default: ``None`` (uses ``kdim=embed_dim``).
+        vdim: Total number of features for values. Default: ``None`` (uses ``vdim=embed_dim``).
+        batch_first: If ``True``, then the input and output tensors are provided
+            as (batch, seq, feature). Default: ``False`` (seq, batch, feature).

+                For a binary mask, a ``True`` value indicates that the corresponding ``key`` value will be ignored for
+                the purpose of attention. For a float mask, it will be directly added to the corresponding ``key`` value.
+            need_weights: If specified, returns ``attn_output_weights`` in addition to ``attn_outputs``.
+                Set ``need_weights=False`` to use the optimized ``scaled_dot_product_attention``
+                and achieve the best performance for MHA.
+                Default: ``True``.
+            attn_mask: If specified, a 2D or 3D mask preventing attention to certain positions. Must be of shape
+                :math:`(L, S)` or :math:`(N\cdot\text{num\_heads}, L, S)`, where :math:`N` is the batch size,
+                :math:`L` is the target sequence length, and :math:`S` is the source sequence length. A 2D mask will be
+                broadcasted across the batch while a 3D mask allows for a different mask for each entry in the batch.
+                Binary and float masks are supported. For a binary mask, a ``True`` value indicates that the
+                corresponding position is not allowed to attend. For a float mask, the mask values will be added to
+                the attention weight.
+                If both attn_mask and key_padding_mask are supplied, their types should match.
+            average_attn_weights: If true, indicates that the returned ``attn_weights`` should be averaged across
+                heads. Otherwise, ``attn_weights`` are provided separately per head. Note that this flag only has an
+                effect when ``need_weights=True``. Default: ``True`` (i.e. average weights across heads)
+            is_causal: If specified, applies a causal mask as attention mask.
+                Default: ``False``.
+                Warning:
+                ``is_causal`` provides a hint that ``attn_mask`` is the
+                causal mask. Providing incorrect hints can result in
+                incorrect execution, including forward and backward
+                compatibility.
+
+        Outputs:
+            - **attn_output** - Attention outputs of shape :math:`(L, E)` when input is unbatched,
+              :math:`(L, N, E)` when ``batch_first=False`` or :math:`(N, L, E)` when ``batch_first=True``,
+              where :math:`L` is the target sequence length, :math:`N` is the batch size, and :math:`E` is the
+              embedding dimension ``embed_dim``.
+            - **attn_output_weights** - Only returned when ``need_weights=True``. If ``average_attn_weights=True``,
+              returns attention weights averaged across heads of shape :math:`(L, S)` when input is unbatched or
+              :math:`(N, L, S)`, where :math:`N` is the batch size, :math:`L` is the target sequence length, and
+              :math:`S` is the source sequence length. If ``average_attn_weights=False``, returns attention weights per
+              head of shape :math:`(\text{num\_heads}, L, S)` when input is unbatched or :math:`(N, \text{num\_heads}, L, S)`.

+    As described in

+    Moustapha Ciss\u00e9, David Grangier, and Herv\u00e9 J\u00e9gou
+    <https://arxiv.org/abs/1609.04309>`__.
+"""
+        r"""
+    Adaptive softmax is an approximate strategy for training models with large
+    output spaces. It is most effective when the label distribution is highly
+    imbalanced, for example in natural language modelling, where the word
+    frequency distribution approximately follows the `Zipf's law`_.
+
+    Adaptive softmax partitions the labels into several clusters, according to
+    their frequency. These clusters may contain different number of targets
+    each.
+    Additionally, clusters containing less frequent labels assign lower
+    dimensional embeddings to those labels, which speeds up the computation.
+    For each minibatch, only clusters for which at least one target is
+    present are evaluated.
+
+    The idea is that the clusters which are accessed frequently
+    (like the first one, containing most frequent labels), should also be cheap
+    to compute -- that is, contain a small number of assigned labels.
+
+    We highly recommend taking a look at the original paper for more details.
+
+    * :attr:`cutoffs` should be an ordered Sequence of integers sorted
+      in the increasing order.
+      It controls number of clusters and the partitioning of targets into
+      clusters. For example setting ``cutoffs = [10, 100, 1000]``
+      means that first `10` targets will be assigned
+      to the 'head' of the adaptive softmax, targets `11, 12, ..., 100` will be
+      assigned to the first cluster, and targets `101, 102, ..., 1000` will be
+      assigned to the second cluster, while targets
+      `1001, 1002, ..., n_classes - 1` will be assigned
+      to the last, third cluster.
+
+    * :attr:`div_value` is used to compute the size of each additional cluster,
+      which is given as
+      :math:`\left\lfloor\frac{\texttt{in\_features}}{\texttt{div\_value}^{idx}}\right\rfloor`,
+      where :math:`idx` is the cluster index (with clusters
+      for less frequent words having larger indices,
+      and indices starting from :math:`1`).
+
+    * :attr:`head_bias` if set to True, adds a bias term to the 'head' of the
+      adaptive softmax. See paper for details. Set to False in the official
+      implementation.
+
+    .. warning::
+        Labels passed as inputs to this module should be sorted according to
+        their frequency. This means that the most frequent label should be

+        label should be represented by the index `n_classes - 1`.

+    r"""Applies Batch Normalization over a 2D or 3D input.
+
+    Method described in the paper
+    `Batch Normalization: Accelerating Deep Network Training by Reducing
+    Internal Covariate Shift <https://arxiv.org/abs/1502.03167>`__ .
+
+    .. math::
+
+        y = \frac{x - \mathrm{E}[x]}{\sqrt{\mathrm{Var}[x] + \epsilon}} * \gamma + \beta
+
+    The mean and standard-deviation are calculated per-dimension over
+    the mini-batches and :math:`\gamma` and :math:`\beta` are learnable parameter vectors
+    of size `C` (where `C` is the number of features or channels of the input). By default, the
+    elements of :math:`\gamma` are set to 1 and the elements of :math:`\beta` are set to 0.
+    At train time in the forward pass, the variance is calculated via the biased estimator,
+    equivalent to ``torch.var(input, correction=0)``. However, the value stored in the
+    moving average of the variance is calculated via the unbiased  estimator, equivalent to
+    ``torch.var(input, correction=1)``.
+
+    Also by default, during training this layer keeps running estimates of its
+    computed mean and variance, which are then used for normalization during
+    evaluation. The running estimates are kept with a default :attr:`momentum`
+    of 0.1.
+
+    If :attr:`track_running_stats` is set to ``False``, this layer then does not
+    keep running estimates, and batch statistics are instead used during
+    evaluation time as well.
+
+    .. note::
+        This :attr:`momentum` argument is different from one used in optimizer
+        classes and the conventional notion of momentum. Mathematically, the
+        update rule for running statistics here is
+        :math:`\hat{x}_\text{new} = (1 - \text{momentum}) \times \hat{x} + \text{momentum} \times x_t`,
+        where :math:`\hat{x}` is the estimated statistic and :math:`x_t` is the
+        new observed value.
+
+    Because the Batch Normalization is done over the `C` dimension, computing statistics
+    on `(N, L)` slices, it's common terminology to call this Temporal Batch Normalization.
+
+    Args:
+        num_features: number of features or channels :math:`C` of the input
+        eps: a value added to the denominator for numerical stability.
+            Default: 1e-5
+        momentum: the value used for the running_mean and running_var
+            computation. Can be set to ``None`` for cumulative moving average
+            (i.e. simple average). Default: 0.1

+    r"""A sequential container.
+
+    Modules will be added to it in the order they are passed in the
+    constructor. Alternatively, an ``OrderedDict`` of modules can be
+    passed in. The ``forward()`` method of ``Sequential`` accepts any
+    input and forwards it to the first module it contains. It then
+    "chains" outputs to inputs sequentially for each subsequent module,
+    finally returning the output of the last module.
+
+    The value a ``Sequential`` provides over manually calling a sequence
+    of modules is that it allows treating the whole container as a
+    single module, such that performing a transformation on the
+    ``Sequential`` applies to each of the modules it stores (which are
+    each a registered submodule of the ``Sequential``).
+
+    What's the difference between a ``Sequential`` and a
+    :class:`torch.nn.ModuleList`? A ``ModuleList`` is exactly what it
+    sounds like--a list for storing ``Module`` s! On the other hand,
+    the layers in a ``Sequential`` are connected in a cascading way.
+
+    Example::
+
+        # Using Sequential to create a small model. When `model` is run,
+        # input will first be passed to `Conv2d(1,20,5)`. The output of
+        # `Conv2d(1,20,5)` will be used as the input to the first
+        # `ReLU`; the output of the first `ReLU` will become the input
+        # for `Conv2d(20,64,5)`. Finally, the output of
+        # `Conv2d(20,64,5)` will be used as input to the second `ReLU`
+        model = nn.Sequential(
+            nn.Conv2d(1, 20, 5), nn.ReLU(), nn.Conv2d(20, 64, 5), nn.ReLU()

+                         The values of these weights are sampled from

+        bias (Tensor):   the learnable bias of the module of shape (out_channels)
+                         If :attr:`bias` is ``True``, then the values of these weights are
+                         sampled from :math:`\mathcal{U}(-\sqrt{k}, \sqrt{k})` where

+    :math:`L` is the total number of blocks. (This is exactly the

+    of shape :math:`(N, C, \text{output\_size}[0], \text{output\_size}[1], \dots)`

+
+    where :math:`d` is over all spatial dimensions.
+
+    * :attr:`output_size` describes the spatial shape of the large containing

+      with ``stride > 0``.
+
+    The :attr:`padding`, :attr:`stride` and :attr:`dilation` arguments specify

+
+        When the ``divisor`` tensor contains no zero elements, then
+        ``fold`` and ``unfold`` operations are inverses of each
+        other (up to constant divisor).

+
+    Therefore, indexing :attr:`output` at the last dimension (column dimension)

+
+        ::

+        >>> divisor = fold(unfold(input_ones))
+
+        When the ``divisor`` tensor contains no zero elements, then
+        ``fold`` and ``unfold`` operations are inverses of each
+        other (up to constant divisor).

+
+    The mean and standard-deviation are calculated per-dimension separately
+    for each object in a mini-batch. :math:`\gamma` and :math:`\beta` are learnable parameter vectors
+    of size `C` (where `C` is the number of features or channels of the input) if :attr:`affine` is ``True``.
+    The variance is calculated via the biased estimator, equivalent to
+    `torch.var(input, correction=0)`.
+
+    By default, this layer uses instance statistics computed from input data in
+    both training and evaluation modes.
+
+    If :attr:`track_running_stats` is set to ``True``, during training this

+        :class:`LayerNorm` is usually applied on entire sample and often in NLP

+class LazyModuleMixin:
+    r"""A mixin for modules that lazily initialize parameters, also known as "lazy modules".
+
+    .. warning:
+        Lazy modules are an experimental new feature under active development,
+        and their API is likely to change.
+
+    Modules that lazily initialize parameters, or "lazy modules",
+    derive the shapes of their parameters from the first input(s)
+    to their forward method. Until that first forward they contain
+    :class:`torch.nn.UninitializedParameter` s that should not be accessed
+    or used, and afterward they contain regular :class:`torch.nn.Parameter` s.
+    Lazy modules are convenient since they don't require computing some
+    module arguments, like the :attr:`in_features` argument of a
+    typical :class:`torch.nn.Linear`.
+
+    After construction, networks with lazy modules should first
+    be converted to the desired dtype and placed on the expected device.
+    This is because lazy modules only perform shape inference so the usual dtype
+    and device placement behavior applies.
+    The lazy modules should then perform "dry runs" to initialize all the components in the module.
+    These "dry runs" send inputs of the correct size, dtype, and device through
+    the network and to each one of its lazy modules. After this the network can be used as usual.

+    )
+    >>> # attaches an optimizer, since parameters can now be used as usual
+    >>> optim = torch.optim.SGD(lazy_mlp.parameters(), lr=0.01)
+
+    A final caveat when using lazy modules is that the order of initialization of a network's
+    parameters may change, since the lazy modules are always initialized after other modules.
+    For example, if the LazyMLP class defined above had a :class:`torch.nn.LazyLinear` module
+    first and then a regular :class:`torch.nn.Linear` second, the second module would be
+    initialized on construction and the first module would be initialized during the first dry run.
+    This can cause the parameters of a network using lazy modules to be initialized differently
+    than the parameters of a network without lazy modules as the order of parameter initializations,
+    which often depends on a stateful random number generator, is different.
+    Check :doc:`/notes/randomness` for more details.
+
+    Lazy modules can be serialized with a state dict like other modules. For example:
+
+    >>> lazy_mlp = LazyMLP()
+    >>> # The state dict shows the uninitialized parameters
+    >>> lazy_mlp.state_dict()
+    OrderedDict({'fc1.weight': <UninitializedParameter>,
+                 'fc1.bias': <UninitializedParameter>,
+                 'fc2.weight': <UninitializedParameter>,
+                 'fc2.bias': <UninitializedParameter>})
+
+    Lazy modules can load regular :class:`torch.nn.Parameter` s (i.e. you can serialize/deserialize
+    initialized LazyModules and they will remain initialized)
+
+
+    >>> full_mlp = LazyMLP()
+    >>> # Dry run to initialize another module
+    >>> full_mlp.forward(torch.ones(10, 1))
+    >>> # Load an initialized state into a lazy module
+    >>> lazy_mlp.load_state_dict(full_mlp.state_dict())
+    >>> # The state dict now holds valid values
+    >>> lazy_mlp.state_dict()

+    problem with `C` classes.
+
+    If provided, the optional argument :attr:`weight` should be a 1D Tensor assigning
+    weight to each of the classes. This is particularly useful when you have an
+    unbalanced training set.
+
+    The `input` given through a forward call is expected to contain
+    log-probabilities of each class. `input` has to be a Tensor of size either
+    :math:`(minibatch, C)` or :math:`(minibatch, C, d_1, d_2, ..., d_K)`
+    with :math:`K \geq 1` for the `K`-dimensional case. The latter is useful for
+    higher dimension inputs, such as computing NLL loss per-pixel for 2D images.
+
+    Obtaining log-probabilities in a neural network is easily achieved by
+    adding a  `LogSoftmax`  layer in the last layer of your network.
+    You may use `CrossEntropyLoss` instead, if you prefer not to add an extra
+    layer.
+
+    The `target` that this loss expects should be a class index in the range :math:`[0, C-1]`
+    where `C = number of classes`; if `ignore_index` is specified, this loss also accepts
+    this class index (this index may not necessarily be in the class range).

+            when :attr:`reduce` is ``False``. Default: ``None``
+        ignore_index (int, optional): Specifies a target value that is ignored
+            and does not contribute to the input gradient. When
+            :attr:`size_average` is ``True``, the loss is averaged over
+            non-ignored targets.
+        reduce (bool, optional): Deprecated (see :attr:`reduction`). By default, the

+
+    For tensors of the same shape :math:`y_{\text{pred}},\ y_{\text{true}}`,
+    where :math:`y_{\text{pred}}` is the :attr:`input` and :math:`y_{\text{true}}` is the

+
+    To avoid underflow issues when computing this quantity, this loss expects the argument
+    :attr:`input` in the log-space. The argument :attr:`target` may also be provided in the
+    log-space if :attr:`log_target`\ `= True`.
+
+    To summarise, this function is roughly equivalent to computing

+
+    .. note::
+        As all the other losses in PyTorch, this function expects the first argument,
+        :attr:`input`, to be the output of the model (e.g. the neural network)
+        and the second, :attr:`target`, to be the observations in the dataset.
+        This differs from the standard mathematical notation :math:`KL(P\ ||\ Q)` where

+
+    .. warning::
+        :attr:`reduction`\ `= "mean"` doesn't return the true KL divergence value, please use

+    between 0 and 1.
+
+    It's possible to trade off recall and precision by adding weights to positive examples.
+    In the case of multi-label classification the loss can be described as:
+
+    .. math::
+        \ell_c(x, y) = L_c = \{l_{1,c},\dots,l_{N,c}\}^\top, \quad
+        l_{n,c} = - w_{n,c} \left[ p_c y_{n,c} \cdot \log \sigma(x_{n,c})
+        + (1 - y_{n,c}) \cdot \log (1 - \sigma(x_{n,c})) \right],
+
+    where :math:`c` is the class number (:math:`c > 1` for multi-label binary classification,
+    :math:`c = 1` for single-label binary classification),
+    :math:`n` is the number of the sample in the batch and
+    :math:`p_c` is the weight of the positive answer for the class :math:`c`.
+
+    :math:`p_c > 1` increases the recall, :math:`p_c < 1` increases the precision.
+
+    For example, if a dataset contains 100 positive and 300 negative examples of a single class,
+    then ``pos_weight`` for the class should be equal to :math:`\frac{300}{100}=3`.
+    The loss would act as if the dataset contains :math:`3\times 100=300` positive examples.
+
+    Examples:
+
+        >>> target = torch.ones([10, 64], dtype=torch.float32)  # 64 classes, batch size = 10
+        >>> output = torch.full([10, 64], 1.5)  # A prediction (logit)

+        >>> criterion(output, target)  # -log(sigmoid(1.5))
+        tensor(0.20...)
+
+    In the above example, the ``pos_weight`` tensor's elements correspond to the 64 distinct classes
+    in a multi-label binary classification scenario. Each element in ``pos_weight`` is designed to adjust the
+    loss function based on the imbalance between negative and positive samples for the respective class.
+    This approach is useful in datasets with varying levels of class imbalance, ensuring that the loss
+    calculation accurately accounts for the distribution in each class.

+            on :attr:`size_average`. When :attr:`reduce` is ``False``, returns a loss per

+        reduction (str, optional): Specifies the reduction to apply to the output:

+            be applied, ``'mean'``: the weighted mean of the output is taken,
+            ``'sum'``: the output will be summed. Note: :attr:`size_average`
+            and :attr:`reduce` are in the process of being deprecated, and in

+            :attr:`reduction`. Default: ``'mean'``
+        label_smoothing (float, optional): A float in [0.0, 1.0]. Specifies the amount
+            of smoothing when computing the loss, where 0.0 means no smoothing. The targets
+            become a mixture of the original ground truth and a uniform distribution as described in
+            `Rethinking the Inception Architecture for Computer Vision <https://arxiv.org/abs/1512.00567>`__. Default: :math:`0.0`.
+
+    Shape:
+        - Input: Shape :math:`(C)`, :math:`(N, C)` or :math:`(N, C, d_1, d_2, ..., d_K)` with :math:`K \geq 1`
+          in the case of `K`-dimensional loss.
+        - Target: If containing class indices, shape :math:`()`, :math:`(N)` or :math:`(N, d_1, d_2, ..., d_K)` with
+          :math:`K \geq 1` in the case of K-dimensional loss where each value should be between :math:`[0, C)`. The
+          target data type is required to be long when using class indices. If containing class probabilities, the
+          target must be the same shape input, and each value should be between :math:`[0, 1]`. This means the target
+          data type is required to be float when using class probabilities. Note that PyTorch does not strictly enforce
+          probability constraints on the class probabilities and that it is the user's responsibility to ensure
+          ``target`` contains valid probability distributions (see below examples section for more details).
+        - Output: If reduction is 'none', shape :math:`()`, :math:`(N)` or :math:`(N, d_1, d_2, ..., d_K)` with :math:`K \geq 1`
+          in the case of K-dimensional loss, depending on the shape of the input. Otherwise, scalar.

+    .. note::
+        When ``target`` contains class probabilities, it should consist of soft labels—that is,
+        each ``target`` entry should represent a probability distribution over the possible classes for a given data sample,
+        with individual probabilities between ``[0,1]`` and the total distribution summing to 1.
+        This is why the :func:`softmax()` function is applied to the ``target`` in the class probabilities example above.
+
+        PyTorch does not validate whether the values provided in ``target`` lie in the range ``[0,1]``
+        or whether the distribution of each data sample sums to ``1``.
+        No warning will be raised and it is the user's responsibility
+        to ensure that ``target`` contains valid probability distributions.
+        Providing arbitrary values may yield misleading loss values and unstable gradients during training.

+        https://www.cs.toronto.edu/~graves/icml_2006.pdf
+
+    Note:
+        In order to use CuDNN, the following must be satisfied: the :attr:`targets` must be
+        in concatenated format, all :attr:`input_lengths` must be `T`.  :math:`blank=0`,
+        :attr:`target_lengths` :math:`\leq 256`, the integer arguments must be of
+        dtype :attr:`torch.int32`, and the :attr:`log_probs` itself must be of
+        dtype :attr:`torch.float32`.
+
+        The regular implementation uses the (more common in PyTorch) `torch.long` dtype.
+
+
+    Note:
+        In some circumstances when using the CUDA backend with CuDNN, this operator
+        may select a nondeterministic algorithm to increase performance. If this is
+        undesirable, you can try to make the operation deterministic (potentially at
+        a performance cost) by setting ``torch.backends.cudnn.deterministic =
+        True``.
+        Please see the notes on :doc:`/notes/randomness` for background.

+
+        Args:

+            prepend (bool): If ``True``, the provided ``hook`` will be fired
+                before all existing ``forward`` hooks on this
+                :class:`torch.nn.Module`. Otherwise, the provided
+                ``hook`` will be fired after all existing ``forward`` hooks on

+                :func:`register_module_forward_hook` will fire before all hooks
+                registered by this method.
+                Default: ``False``
+            with_kwargs (bool): If ``True``, the ``hook`` will be passed the
+                kwargs given to the forward function.
+                Default: ``False``
+            always_call (bool): If ``True`` the ``hook`` will be run regardless of

+        pad should be at most half of effective kernel size.

+          the second `int` for the height dimension and the third `int` for the width dimension
+
+    Args:
+        kernel_size: the size of the window
+        stride: the stride of the window. Default value is :attr:`kernel_size`
+        padding: implicit zero padding to be added on all three sides
+        ceil_mode: when True, will use `ceil` instead of `floor` to compute the output shape
+        count_include_pad: when True, will include the zero-padding in the averaging calculation
+        divisor_override: if specified, it will be used as divisor, otherwise :attr:`kernel_size` will be used
+
+    Shape:
+        - Input: :math:`(N, C, D_{in}, H_{in}, W_{in})` or :math:`(C, D_{in}, H_{in}, W_{in})`.
+        - Output: :math:`(N, C, D_{out}, H_{out}, W_{out})` or

+
+          .. math::
+              D_{out} = \left\lfloor\frac{D_{in} + 2 \times \text{padding}[0] -

+          + \text{padding}[0]`, we skip the last window as it would start in the padded region,

+            Note that this does not apply to hidden or cell states. See the

+        dropout: If non-zero, introduces a `Dropout` layer on the outputs of each
+            RNN layer except the last layer, with dropout probability equal to

+
+    Apply a multi-layer long short-term memory (LSTM) RNN to an input sequence.
+    For each element in the input sequence, each layer computes the following
+    function:
+
+    .. math::
+        \begin{array}{ll} \\
+            i_t = \sigma(W_{ii} x_t + b_{ii} + W_{hi} h_{t-1} + b_{hi}) \\
+            f_t = \sigma(W_{if} x_t + b_{if} + W_{hf} h_{t-1} + b_{hf}) \\
+            g_t = \tanh(W_{ig} x_t + b_{ig} + W_{hg} h_{t-1} + b_{hg}) \\
+            o_t = \sigma(W_{io} x_t + b_{io} + W_{ho} h_{t-1} + b_{ho}) \\
+            c_t = f_t \odot c_{t-1} + i_t \odot g_t \\
+            h_t = o_t \odot \tanh(c_t) \\
+        \end{array}
+
+    where :math:`h_t` is the hidden state at time `t`, :math:`c_t` is the cell
+    state at time `t`, :math:`x_t` is the input at time `t`, :math:`h_{t-1}`
+    is the hidden state of the layer at time `t-1` or the initial hidden
+    state at time `0`, and :math:`i_t`, :math:`f_t`, :math:`g_t`,
+    :math:`o_t` are the input, forget, cell, and output gates, respectively.
+    :math:`\sigma` is the sigmoid function, and :math:`\odot` is the Hadamard product.
+
+    In a multilayer LSTM, the input :math:`x^{(l)}_t` of the :math:`l` -th layer
+    (:math:`l \ge 2`) is the hidden state :math:`h^{(l-1)}_t` of the previous layer multiplied by
+    dropout :math:`\delta^{(l-1)}_t` where each :math:`\delta^{(l-1)}_t` is a Bernoulli random
+    variable which is :math:`0` with probability :attr:`dropout`.
+
+    If ``proj_size > 0`` is specified, LSTM with projections will be used. This changes
+    the LSTM cell in the following way. First, the dimension of :math:`h_t` will be changed from
+    ``hidden_size`` to ``proj_size`` (dimensions of :math:`W_{hi}` will be changed accordingly).
+    Second, the output hidden state of each layer will be multiplied by a learnable projection
+    matrix: :math:`h_t = W_{hr}h_t`. Note that as a consequence of this, the output
+    of LSTM network will be of different shape as well. See Inputs/Outputs sections below for exact
+    dimensions of all variables. You can find more details in https://arxiv.org/abs/1402.1128.
+
+    Args:
+        input_size: The number of expected features in the input `x`
+        hidden_size: The number of features in the hidden state `h`
+        num_layers: Number of recurrent layers. E.g., setting ``num_layers=2``
+            would mean stacking two LSTMs together to form a `stacked LSTM`,
+            with the second LSTM taking in outputs of the first LSTM and
+            computing the final results. Default: 1
+        bias: If ``False``, then the layer does not use bias weights `b_ih` and `b_hh`.
+            Default: ``True``
+        batch_first: If ``True``, then the input and output tensors are provided
+            as `(batch, seq, feature)` instead of `(seq, batch, feature)`.
+            Note that this does not apply to hidden or cell states. See the
+            Inputs/Outputs sections below for details.  Default: ``False``
+        dropout: If non-zero, introduces a `Dropout` layer on the outputs of each
+            LSTM layer except the last layer, with dropout probability equal to
+            :attr:`dropout`. Default: 0
+        bidirectional: If ``True``, becomes a bidirectional LSTM. Default: ``False``
+        proj_size: If ``> 0``, will use LSTM with projections of corresponding size. Default: 0
+

+            Only present when ``bidirectional=True`` and ``proj_size > 0`` was specified.

+
+    .. note::
+        For bidirectional LSTMs, forward and backward are directions 0 and 1 respectively.
+        Example of splitting the output layers when ``batch_first=False``:
+        ``output.view(seq_len, batch, num_directions, hidden_size)``.
+
+    .. note::
+        For bidirectional LSTMs, `h_n` is not equivalent to the last element of `output`; the

+
+    In a multilayer GRU, the input :math:`x^{(l)}_t` of the :math:`l` -th layer
+    (:math:`l \ge 2`) is the hidden state :math:`h^{(l-1)}_t` of the previous layer multiplied by

+    variable which is :math:`0` with probability :attr:`dropout`.
+

+            Note that this does not apply to hidden or cell states. See the
+            Inputs/Outputs sections below for details.  Default: ``False``
+        dropout: If non-zero, introduces a `Dropout` layer on the outputs of each
+            GRU layer except the last layer, with dropout probability equal to
+            :attr:`dropout`. Default: 0
+        bidirectional: If ``True``, becomes a bidirectional GRU. Default: ``False``
+
+    Inputs: input, h_0
+        * **input**: tensor of shape :math:`(L, H_{in})` for unbatched input,

+          `(h_t)` from the last layer of the GRU, for each `t`. If a
+          :class:`torch.nn.utils.rnn.PackedSequence` has been given as the input, the output
+          will also be a packed sequence.
+        * **h_n**: tensor of shape :math:`(D * \text{num\_layers}, H_{out})` or

+          for the input sequence.

+        For bidirectional GRUs, forward and backward are directions 0 and 1 respectively.
+        Example of splitting the output layers when ``batch_first=False``:
+        ``output.view(seq_len, batch, num_directions, hidden_size)``.
+
+    .. note::
+        ``batch_first`` argument is ignored for unbatched inputs.
+
+    .. note::
+        The calculation of new gate :math:`n_t` subtly differs from the original paper and other frameworks.
+        In the original implementation, the Hadamard product :math:`(\odot)` between :math:`r_t` and the
+        previous hidden state :math:`h_{(t-1)}` is done before the multiplication with the weight matrix
+        `W` and addition of bias:
+
+        .. math::
+            \begin{aligned}
+                n_t = \tanh(W_{in} x_t + b_{in} + W_{hn} ( r_t \odot h_{(t-1)} ) + b_{hn})
+            \end{aligned}
+
+        This is in contrast to PyTorch implementation, which is done after :math:`W_{hn} h_{(t-1)}`
+
+        .. math::
+            \begin{aligned}
+                n_t = \tanh(W_{in} x_t + b_{in} + r_t \odot (W_{hn} h_{(t-1)}+ b_{hn}))
+            \end{aligned}
+
+        This implementation differs on purpose for efficiency.

+class Embedding(Module):
+    r"""A simple lookup table that stores embeddings of a fixed dictionary and size.
+
+    This module is often used to store word embeddings and retrieve them using indices.
+    The input to the module is a list of indices, and the output is the corresponding
+    word embeddings.
+
+    Args:
+        num_embeddings (int): size of the dictionary of embeddings
+        embedding_dim (int): the size of each embedding vector
+        padding_idx (int, optional): If specified, the entries at :attr:`padding_idx` do not contribute to the gradient;
+                                     therefore, the embedding vector at :attr:`padding_idx` is not updated during training,
+                                     i.e. it remains as a fixed "pad". For a newly constructed Embedding,
+                                     the embedding vector at :attr:`padding_idx` will default to all zeros,
+                                     but can be updated to another value to be used as the padding vector.
+        max_norm (float, optional): If given, each embedding vector with norm larger than :attr:`max_norm`
+                                    is renormalized to have norm :attr:`max_norm`.
+        norm_type (float, optional): The p of the p-norm to compute for the :attr:`max_norm` option. Default ``2``.
+        scale_grad_by_freq (bool, optional): If given, this will scale gradients by the inverse of frequency of
+                                                the words in the mini-batch. Default ``False``.
+        sparse (bool, optional): If ``True``, gradient w.r.t. :attr:`weight` matrix will be a sparse tensor.
+                                 See Notes for more details regarding sparse gradients.
+
+    Attributes:
+        weight (Tensor): the learnable weights of the module of shape (num_embeddings, embedding_dim)
+                         initialized from :math:`\mathcal{N}(0, 1)`
+
+    Shape:
+        - Input: :math:`(*)`, IntTensor or LongTensor of arbitrary shape containing the indices to extract
+        - Output: :math:`(*, H)`, where `*` is the input shape and :math:`H=\text{embedding\_dim}`
+
+    .. note::
+        Keep in mind that only a limited number of optimizers support
+        sparse gradients: currently it's :class:`optim.SGD` (`CUDA` and `CPU`),
+        :class:`optim.SparseAdam` (`CUDA` and `CPU`) and :class:`optim.Adagrad` (`CPU`)
+
+    .. note::
+        When :attr:`max_norm` is not ``None``, :class:`Embedding`'s forward method will modify the
+        :attr:`weight` tensor in-place. Since tensors needed for gradient computations cannot be
+        modified in-place, performing a differentiable operation on ``Embedding.weight`` before
+        calling :class:`Embedding`'s forward method requires cloning ``Embedding.weight`` when
+        :attr:`max_norm` is not ``None``. For example::
+
+            n, d, m = 3, 5, 7
+            embedding = nn.Embedding(n, d, max_norm=1.0)
+            W = torch.randn((m, d), requires_grad=True)
+            idx = torch.tensor([1, 2])
+            a = (
+                embedding.weight.clone() @ W.t()
+            )  # weight must be cloned for this to be differentiable
+            b = embedding(idx) @ W.t()  # modifies weight in-place
+            out = a.unsqueeze(0) + b.unsqueeze(1)
+            loss = out.sigmoid().prod()
+            loss.backward()

+
+    However, :class:`~torch.nn.EmbeddingBag` is much more time and memory efficient than using a chain of these
+    operations.
+
+    EmbeddingBag also supports per-sample weights as an argument to the forward
+    pass. This scales the output of the Embedding before performing a weighted
+    reduction as specified by ``mode``. If :attr:`per_sample_weights` is passed, the

+        mode (str, optional): ``"sum"``, ``"mean"`` or ``"max"``. Specifies the way to reduce the bag.

+                                 in the bag, ``"max"`` computes the max value over each bag.

+        include_last_offset (bool, optional): if ``True``, the size of offsets is equal to the number of bags + 1.
+                                              The last element is the size of the input, or the ending index position
+                                              of the last bag (sequence). This matches the CSR format. Ignored when
+                                              input is 2D. Default ``False``.
+        padding_idx (int, optional): If specified, the entries at :attr:`padding_idx` do not contribute to the
+                                     gradient; therefore, the embedding vector at :attr:`padding_idx` is not updated

+                                     Note that the embedding vector at :attr:`padding_idx` is excluded from the

+        - at most one of ``src_mask`` and ``src_key_padding_mask`` is passed
+        - if src is a `NestedTensor <https://pytorch.org/docs/stable/nested.html>`_, neither ``src_mask``
+          nor ``src_key_padding_mask`` is passed
+        - the two ``LayerNorm`` instances have a consistent ``eps`` value (this will naturally be the case
+          unless the caller has manually modified one without modifying the other)
+
+        If the optimized implementation is in use, a
+        `NestedTensor <https://pytorch.org/docs/stable/nested.html>`_ can be
+        passed for ``src`` to represent padding more efficiently than using a padding
+        mask. In this case, a `NestedTensor <https://pytorch.org/docs/stable/nested.html>`_ will be
+        returned, and an additional speedup proportional to the fraction of the input that
+        is padding can be expected.

+    intent of this layer is as a reference implementation for foundational understanding

+    Given the fast pace of innovation in transformer-like architectures, we recommend

+    to build efficient layers from building blocks in core or using higher
+    level libraries from the `PyTorch Ecosystem <https://landscape.pytorch.org/>`_.
+

+        d_model: the number of expected features in the input (required).

+        dim_feedforward: the dimension of the feedforward network model (default=2048).
+        dropout: the dropout value (default=0.1).
+        activation: the activation function of the intermediate layer, can be a string
+            ("relu" or "gelu") or a unary callable. Default: relu
+        layer_norm_eps: the eps value in layer normalization components (default=1e-5).
+        batch_first: If ``True``, then the input and output tensors are provided
+            as (batch, seq, feature). Default: ``False`` (seq, batch, feature).
+        norm_first: if ``True``, layer norm is done prior to self attention, multihead
+            attention and feedforward operations, respectively. Otherwise it's done after.

+class Upsample(Module):
+    r"""Upsamples a given multi-channel 1D (temporal), 2D (spatial) or 3D (volumetric) data.
+
+    The input data is assumed to be of the form
+    `minibatch x channels x [optional depth] x [optional height] x width`.
+    Hence, for spatial inputs, we expect a 4D Tensor and for volumetric inputs, we expect a 5D Tensor.
+
+    The algorithms available for upsampling are nearest neighbor and linear,
+    bilinear, bicubic and trilinear for 3D, 4D and 5D input Tensor,
+    respectively.
+
+    One can either give a :attr:`scale_factor` or the target output :attr:`size` to
+    calculate the output size. (You cannot give both, as it is ambiguous)
+
+    Args:
+        size (int or Tuple[int] or Tuple[int, int] or Tuple[int, int, int], optional):
+            output spatial sizes
+        scale_factor (float or Tuple[float] or Tuple[float, float] or Tuple[float, float, float], optional):
+            multiplier for spatial size. Has to match input size if it is a tuple.
+        mode (str, optional): the upsampling algorithm: one of ``'nearest'``,
+            ``'linear'``, ``'bilinear'``, ``'bicubic'`` and ``'trilinear'``.
+            Default: ``'nearest'``
+        align_corners (bool, optional): if ``True``, the corner pixels of the input
+            and output tensors are aligned, and thus preserving the values at
+            those pixels. This only has effect when :attr:`mode` is
+            ``'linear'``, ``'bilinear'``, ``'bicubic'``, or ``'trilinear'``.
+            Default: ``False``
+        recompute_scale_factor (bool, optional): recompute the scale_factor for use in the
+            interpolation calculation. If `recompute_scale_factor` is ``True``, then
+            `scale_factor` must be passed in and `scale_factor` is used to compute the
+            output `size`. The computed output `size` will be used to infer new scales for
+            the interpolation. Note that when `scale_factor` is floating-point, it may differ
+            from the recomputed `scale_factor` due to rounding and precision issues.
+            If `recompute_scale_factor` is ``False``, then `size` or `scale_factor` will
+            be used directly for interpolation.
+
+    Shape:
+        - Input: :math:`(N, C, W_{in})`, :math:`(N, C, H_{in}, W_{in})` or :math:`(N, C, D_{in}, H_{in}, W_{in})`
+        - Output: :math:`(N, C, W_{out})`, :math:`(N, C, H_{out}, W_{out})`
+          or :math:`(N, C, D_{out}, H_{out}, W_{out})`, where
+
+    .. math::
+        D_{out} = \left\lfloor D_{in} \times \text{scale\_factor} \right\rfloor
+
+    .. math::

+
+    .. math::
+        W_{out} = \left\lfloor W_{in} \times \text{scale\_factor} \right\rfloor
+
+    .. warning::
+        With ``align_corners = True``, the linearly interpolating modes
+        (`linear`, `bilinear`, `bicubic`, and `trilinear`) don't proportionally
+        align the output and input pixels, and thus the output values can depend
+        on the input size. This was the default behavior for these modes up to
+        version 0.3.1. Since then, the default behavior is
+        ``align_corners = False``. See below for concrete examples on how this
+        affects the outputs.
+
+    .. note::
+        If you want downsampling/general resizing, you should use :func:`~nn.functional.interpolate`.

+    r"""Implements data parallelism at the module level.
+
+    This container parallelizes the application of the given :attr:`module` by
+    splitting the input across the specified devices by chunking in the batch
+    dimension (other objects will be copied once per device). In the forward
+    pass, the module is replicated on each device, and each replica handles a
+    portion of the input. During the backwards pass, gradients from each replica
+    are summed into the original module.
+
+    The batch size should be larger than the number of GPUs used.
+
+    .. warning::
+        It is recommended to use :class:`~torch.nn.parallel.DistributedDataParallel`,
+        instead of this class, to do multi-GPU training, even if there is only a single
+        node. See: :ref:`cuda-nn-ddp-instead` and :ref:`ddp`.
+
+    Arbitrary positional and keyword inputs are allowed to be passed into
+    DataParallel but some types are specially handled. tensors will be
+    **scattered** on dim specified (default 0). tuple, list and dict types will
+    be shallow copied. The other types will be shared among different threads
+    and can be corrupted if written to in the model's forward pass.
+
+    The parallelized :attr:`module` must have its parameters and buffers on
+    ``device_ids[0]`` before running this :class:`~torch.nn.DataParallel`
+    module.
+
+    .. warning::
+        In each forward, :attr:`module` is **replicated** on each device, so any
+        updates to the running module in ``forward`` will be lost. For example,
+        if :attr:`module` has a counter attribute that is incremented in each
+        ``forward``, it will always stay at the initial value because the update
+        is done on the replicas which are destroyed after ``forward``. However,
+        :class:`~torch.nn.DataParallel` guarantees that the replica on
+        ``device[0]`` will have its parameters and buffers sharing storage with
+        the base parallelized :attr:`module`. So **in-place** updates to the
+        parameters or buffers on ``device[0]`` will be recorded. E.g.,
+        :class:`~torch.nn.BatchNorm2d` and :func:`~torch.nn.utils.spectral_norm`
+        rely on this behavior to update the buffers.
+
+    .. warning::
+        Forward and backward hooks defined on :attr:`module` and its submodules
+        will be invoked ``len(device_ids)`` times, each with inputs located on
+        a particular device. Particularly, the hooks are only guaranteed to be
+        executed in correct order with respect to operations on corresponding
+        devices. For example, it is not guaranteed that hooks set via
+        :meth:`~torch.nn.Module.register_forward_pre_hook` be executed before
+        `all` ``len(device_ids)`` :meth:`~torch.nn.Module.forward` calls, but
+        that each such hook be executed before the corresponding
+        :meth:`~torch.nn.Module.forward` call of that device.
+
+    .. warning::
+        When :attr:`module` returns a scalar (i.e., 0-dimensional tensor) in
+        :func:`forward`, this wrapper will return a vector of length equal to
+        number of devices used in data parallelism, containing the result from
+        each device.
+
+    .. note::
+        There is a subtlety in using the
+        ``pack sequence -> recurrent network -> unpack sequence`` pattern in a
+        :class:`~torch.nn.Module` wrapped in :class:`~torch.nn.DataParallel`.
+        See :ref:`pack-rnn-unpack-with-data-parallelism` section in FAQ for

+            ``True``), and therefore the dtype for computation.
+            However, outside the forward and backward passes, parameters are in
+            full precision. Model checkpointing always happens in full
+            precision.

+class DistributedDataParallel(Module, Joinable):
+    r"""Implement distributed data parallelism based on ``torch.distributed`` at module level.
+
+    This container provides data parallelism by synchronizing gradients
+    across each model replica. The devices to synchronize across are
+    specified by the input ``process_group``, which is the entire world
+    by default. Note that ``DistributedDataParallel`` does not chunk or
+    otherwise shard the input across participating GPUs; the user is
+    responsible for defining how to do so, for example through the use
+    of a :class:`DistributedSampler`.
+
+    See also: :ref:`distributed-basics` and :ref:`cuda-nn-ddp-instead`.
+    The same constraints on input as in :class:`torch.nn.DataParallel` apply.
+
+    Creation of this class requires that ``torch.distributed`` to be already
+    initialized, by calling :func:`torch.distributed.init_process_group`.
+
+    ``DistributedDataParallel`` is proven to be significantly faster than
+    :class:`torch.nn.DataParallel` for single-node multi-GPU data
+    parallel training.
+
+    To use ``DistributedDataParallel`` on a host with N GPUs, you should spawn
+    up ``N`` processes, ensuring that each process exclusively works on a single
+    GPU from 0 to N-1. This can be done by either setting
+    ``CUDA_VISIBLE_DEVICES`` for every process or by calling the following API for GPUs,
+
+        >>> # xdoctest: +SKIP("undefined variables")
+        >>> torch.cuda.set_device(i)
+
+    or calling the unified API for :ref:`accelerator<accelerators>`,
+
+        >>> # xdoctest: +SKIP("undefined variables")
+        >>> torch.accelerator.set_device_index(i)
+
+    where i is from 0 to N-1. In each process, you should refer the following
+    to construct this module:
+
+        >>> # xdoctest: +SKIP("undefined variables")
+        >>> if torch.accelerator.is_available():
+        >>>     device_type = torch.accelerator.current_accelerator().type
+        >>>     vendor_backend = torch.distributed.get_default_backend_for_device(device_type)
+        >>>
+        >>> torch.distributed.init_process_group(
+        >>>     backend=vendor_backend, world_size=N, init_method='...'
+        >>> )
+        >>> model = DistributedDataParallel(model, device_ids=[i], output_device=i)
+
+    Or you can use the latest API for initialization:
+
+        >>> torch.distributed.init_process_group(device_id=i)
+
+    In order to spawn up multiple processes per node, you can use either
+    ``torch.distributed.launch`` or ``torch.multiprocessing.spawn``.
+
+    .. note::
+        Please refer to `PyTorch Distributed Overview <https://pytorch.org/tutorials/beginner/dist_overview.html>`__
+        for a brief introduction to all features related to distributed training.
+
+    .. note::
+        ``DistributedDataParallel`` can be used in conjunction with
+        :class:`torch.distributed.optim.ZeroRedundancyOptimizer` to reduce
+        per-rank optimizer states memory footprint. Please refer to
+        `ZeroRedundancyOptimizer recipe <https://pytorch.org/tutorials/recipes/zero_redundancy_optimizer.html>`__
+        for more details.
+
+    .. note:: ``nccl`` backend is currently the fastest and highly recommended
+        backend when using GPUs. This applies to both single-node and
+        multi-node distributed training.
+
+    .. note:: This module also supports mixed-precision distributed training.
+        This means that your model can have different types of parameters such
+        as mixed types of ``fp16`` and ``fp32``, the gradient reduction on these
+        mixed types of parameters will just work fine.
+
+    .. note:: If you use ``torch.save`` on one process to checkpoint the module,
+        and ``torch.load`` on some other processes to recover it, make sure that
+        ``map_location`` is configured properly for every process. Without
+        ``map_location``, ``torch.load`` would recover the module to devices
+        where the module was saved from.
+
+    .. note:: When a model is trained on ``M`` nodes with ``batch=N``, the
+        gradient will be ``M`` times smaller when compared to the same model
+        trained on a single node with ``batch=M*N`` if the loss is summed (NOT
+        averaged as usual) across instances in a batch (because the gradients
+        between different nodes are averaged). You should take this into
+        consideration when you want to obtain a mathematically equivalent
+        training process compared to the local training counterpart. But in most
+        cases, you can just treat a DistributedDataParallel wrapped model, a
+        DataParallel wrapped model and an ordinary model on a single GPU as the
+        same (E.g. using the same learning rate for equivalent batch size).
+
+    .. note::
+        Parameters are never broadcast between processes. The module performs
+        an all-reduce step on gradients and assumes that they will be modified
+        by the optimizer in all processes in the same way. Buffers
+        (e.g. BatchNorm stats) are broadcast from the module in process of rank
+        0, to all other replicas in the system in every iteration.
+
+    .. note::
+        If you are using DistributedDataParallel in conjunction with the
+        :ref:`distributed-rpc-framework`, you should always use
+        :meth:`torch.distributed.autograd.backward` to compute gradients and
+        :class:`torch.distributed.optim.DistributedOptimizer` for optimizing
+        parameters.
+
+        Example::
+
+            >>> # xdoctest: +SKIP("undefined variables")
+            >>> import torch.distributed.autograd as dist_autograd
+            >>> from torch.nn.parallel import DistributedDataParallel as DDP
+            >>> import torch
+            >>> from torch import optim
+            >>> from torch.distributed.optim import DistributedOptimizer
+            >>> import torch.distributed.rpc as rpc
+            >>> from torch.distributed.rpc import RRef
+            >>>
+            >>> t1 = torch.rand((3, 3), requires_grad=True)
+            >>> t2 = torch.rand((3, 3), requires_grad=True)
+            >>> rref = rpc.remote("worker1", torch.add, args=(t1, t2))
+            >>> ddp_model = DDP(my_model)
+            >>>
+            >>> # Setup optimizer
+            >>> optimizer_params = [rref]
+            >>> for param in ddp_model.parameters():
+            >>>     optimizer_params.append(RRef(param))
+            >>>
+            >>> dist_optim = DistributedOptimizer(
+            >>>     optim.SGD,
+            >>>     optimizer_params,
+            >>>     lr=0.05,
+            >>> )
+            >>>
+            >>> with dist_autograd.context() as context_id:
+            >>>     pred = ddp_model(rref.to_here())
+            >>>     loss = loss_func(pred, target)
+            >>>     dist_autograd.backward(context_id, [loss])
+            >>>     dist_optim.step(context_id)
+
+    .. note::
+        DistributedDataParallel currently offers limited support for gradient
+        checkpointing with :meth:`torch.utils.checkpoint`.
+        If the checkpoint is done with use_reentrant=False (recommended), DDP
+        will work as expected without any limitations.
+        If, however, the checkpoint is done with use_reentrant=True (the default),
+        DDP will work as expected when there are no unused parameters in the model
+        and each layer is checkpointed at most once (make sure you are not passing
+        `find_unused_parameters=True` to DDP). We currently do not support the
+        case where a layer is checkpointed multiple times, or when there unused
+        parameters in the checkpointed model.
+
+    .. note::
+        To let a non-DDP model load a state dict from a DDP model,
+        :meth:`~torch.nn.modules.utils.consume_prefix_in_state_dict_if_present`
+        needs to be applied to strip the prefix "module." in the DDP state dict before loading.

+        executing different code.
+
+    .. warning::
+        This module assumes all parameters are registered in the model by the

+        distributed processes are in the same order. The module itself will
+        conduct gradient ``allreduce`` following the reverse order of the
+        registered parameters of the model. In other words, it is users'
+        responsibility to ensure that each distributed process has the exact
+        same model and thus the exact same parameter registration order.
+
+    .. warning::
+        This module allows parameters with non-rowmajor-contiguous strides.
+        For example, your model may contain some parameters whose
+        :class:`torch.memory_format` is ``torch.contiguous_format``
+        and others whose format is ``torch.channels_last``.  However,
+        corresponding parameters in different processes must have the
+        same strides.
+
+    .. warning::
+        This module doesn't work with :func:`torch.autograd.grad` (i.e. it will
+        only work if gradients are to be accumulated in ``.grad`` attributes of
+        parameters).
+
+    .. warning::
+        If you plan on using this module with a ``nccl`` backend or a ``gloo``
+        backend (that uses Infiniband), together with a DataLoader that uses
+        multiple workers, please change the multiprocessing start method to
+        ``forkserver`` (Python 3 only) or ``spawn``. Unfortunately
+        Gloo (that uses Infiniband) and NCCL2 are not fork safe, and you will
+        likely experience deadlocks if you don't change this setting.
+
+    .. warning::
+        You should never try to change your model's parameters after wrapping
+        up your model with ``DistributedDataParallel``. Because, when
+        wrapping up your model with ``DistributedDataParallel``, the constructor
+        of ``DistributedDataParallel`` will register the additional gradient
+        reduction functions on all the parameters of the model itself at the
+        time of construction. If you change the model's parameters afterwards,
+        gradient reduction functions no longer match the correct set of
+        parameters.
+
+    .. warning::
+        Using ``DistributedDataParallel`` in conjunction with the
+        :ref:`distributed-rpc-framework` is experimental and subject to change.
+
+    Args:
+        module (Module): module to be parallelized
+        device_ids (list of int or torch.device): CUDA devices.
+                   1) For single-device modules, ``device_ids`` can
+                   contain exactly one device id, which represents the only
+                   CUDA device where the input module corresponding to this process resides.
+                   Alternatively, ``device_ids`` can also be ``None``.
+                   2) For multi-device modules and CPU modules,
+                   ``device_ids`` must be ``None``.
+
+                   When ``device_ids`` is ``None`` for both cases,
+                   both the input data for the forward pass and the actual module
+                   must be placed on the correct device.
+                   (default: ``None``)
+        output_device (int or torch.device): Device location of output for
+                      single-device CUDA modules. For multi-device modules and
+                      CPU modules, it must be ``None``, and the module itself
+                      dictates the output location. (default: ``device_ids[0]``
+                      for single-device modules)
+        broadcast_buffers (bool): Flag that enables syncing (broadcasting)
+                          buffers of the module at beginning of the ``forward``
+                          function. (default: ``True``)
+        init_sync (bool): Whether to sync during initialization to verify param
+                          shapes and broadcast parameters and buffers.
+                          WARNING: if this is set to False the user is required
+                          to ensure themselves that the weights are the same on
+                          all ranks.
+                          (default: ``True``)
+        process_group: The process group to be used for distributed data
+                       all-reduction. If ``None``, the default process group, which
+                       is created by :func:`torch.distributed.init_process_group`,
+                       will be used. (default: ``None``)
+        bucket_cap_mb: ``DistributedDataParallel`` will bucket parameters into
+                       multiple buckets so that gradient reduction of each
+                       bucket can potentially overlap with backward computation.
+                       :attr:`bucket_cap_mb` controls the bucket size in
+                       MebiBytes (MiB). If ``None``, a default size of 25 MiB
+                       will be used. (default: ``None``)
+        find_unused_parameters (bool): Traverse the autograd graph from all
+                               tensors contained in the return value of the
+                               wrapped module's ``forward`` function. Parameters
+                               that don't receive gradients as part of this
+                               graph are preemptively marked as being ready to
+                               be reduced. In addition, parameters that may have
+                               been used in the wrapped module's ``forward``
+                               function but were not part of loss computation and
+                               thus would also not receive gradients are
+                               preemptively marked as ready to be reduced.
+                               (default: ``False``)
+        check_reduction: This argument is deprecated.
+        gradient_as_bucket_view (bool): When set to ``True``, gradients will be views
+                      pointing to different offsets of ``allreduce`` communication
+                      buckets. This can reduce peak memory usage, where the
+                      saved memory size will be equal to the total gradients
+                      size. Moreover, it avoids the overhead of copying between
+                      gradients and ``allreduce`` communication buckets. When
+                      gradients are views, ``detach_()`` cannot be called on the
+                      gradients. If hitting such errors, please fix it by
+                      referring to the :meth:`~torch.optim.Optimizer.zero_grad`
+                      function in ``torch/optim/optimizer.py`` as a solution.
+                      Note that gradients will be views after first iteration, so
+                      the peak memory saving should be checked after first iteration.
+        static_graph (bool): When set to ``True``, DDP knows the trained graph is
+                     static. Static graph means 1) The set of used and unused
+                     parameters will not change during the whole training loop; in
+                     this case, it does not matter whether users set
+                     ``find_unused_parameters = True`` or not. 2) How the graph is trained
+                     will not change during the whole training loop (meaning there is
+                     no control flow depending on iterations).
+                     When static_graph is set to be ``True``, DDP will support cases that
+                     can not be supported in the past:
+                     1) Reentrant backwards.
+                     2) Activation checkpointing multiple times.
+                     3) Activation checkpointing when model has unused parameters.
+                     4) There are model parameters that are outside of forward function.
+                     5) Potentially improve performance when there are unused parameters,
+                     as DDP will not search graph in each iteration to detect unused
+                     parameters when static_graph is set to be ``True``.
+                     To check whether you can set static_graph to be ``True``, one way is to
+                     check ddp logging data at the end of your previous model training,
+                     if ``ddp_logging_data.get("can_set_static_graph") == True``, mostly you
+                     can set ``static_graph = True`` as well.
+
+                     Example::
+                         >>> # xdoctest: +SKIP("undefined variables")
+                         >>> model_DDP = torch.nn.parallel.DistributedDataParallel(model)
+                         >>> # Training loop
+                         >>> ...
+                         >>> ddp_logging_data = model_DDP._get_ddp_logging_data()
+                         >>> static_graph = ddp_logging_data.get("can_set_static_graph")
+        delay_all_reduce_named_params (list of tuple of str and torch.nn.Parameter): a list
+                    of named parameters whose all reduce will be delayed when the gradient of
+                    the parameter specified in ``param_to_hook_all_reduce`` is ready. Other
+                    arguments of DDP do not apply to named params specified in this argument
+                    as these named params will be ignored by DDP reducer.
+        param_to_hook_all_reduce (torch.nn.Parameter): a parameter to hook delayed all reduce
+                    of parameters specified in ``delay_all_reduce_named_params``.
+        skip_all_reduce_unused_params: When set to True, DDP will skip reducing unused parameters.
+                    This requires that unused parameters remain the same across all ranks throughout
+                    the entire training process. If this condition is not met, it may cause
+                    desynchronization and result in training hang.

+        Context manager for training with uneven inputs across processes in DDP.
+
+        This context manager will keep track of already-joined DDP processes,
+        and "shadow" the forward and backward passes by inserting collective
+        communication operations to match with the ones created by non-joined
+        DDP processes. This will ensure each collective call has a corresponding
+        call by already-joined DDP processes, preventing hangs or errors that
+        would otherwise happen when training with uneven inputs across
+        processes. Alternatively, if the flag ``throw_on_early_termination`` is
+        specified to be ``True``, all trainers will throw an error once one rank
+        runs out of inputs, allowing these errors to be caught and handled
+        according to application logic.
+
+        Once all DDP processes have joined, the context manager will broadcast
+        the model corresponding to the last joined process to all processes to
+        ensure the model is the same across all processes
+        (which is guaranteed by DDP).
+
+        To use this to enable training with uneven inputs across processes,
+        simply wrap this context manager around your training loop. No further
+        modifications to the model or data loading is required.
+
+        .. warning::
+            If the model or training loop this context manager is wrapped around
+            has additional distributed collective operations, such as
+            ``SyncBatchNorm`` in the model's forward pass, then the flag
+            ``throw_on_early_termination`` must be enabled. This is because this
+            context manager is not aware of non-DDP collective communication.
+            This flag will cause all ranks to throw when any one rank
+            exhausts inputs, allowing these errors to be caught and recovered
+            from across all ranks.
+
+        Args:
+            divide_by_initial_world_size (bool): If ``True``, will divide
+                gradients by the initial ``world_size`` DDP training was launched
+                with. If ``False``, will compute the effective world size
+                (number of ranks that have not depleted their inputs yet) and
+                divide gradients by that during allreduce. Set
+                ``divide_by_initial_world_size=True`` to ensure every input
+                sample including the uneven inputs have equal weight in terms of
+                how much they contribute to the global gradient. This is
+                achieved by always dividing the gradient by the initial
+                ``world_size`` even when we encounter uneven inputs. If you set
+                this to ``False``, we divide the gradient by the remaining
+                number of nodes. This ensures parity with training on a smaller
+                ``world_size`` although it also means the uneven inputs would
+                contribute more towards the global gradient. Typically, you
+                would want to set this to ``True`` for cases where the last few
+                inputs of your training job are uneven. In extreme cases, where
+                there is a large discrepancy in the number of inputs, setting
+                this to ``False`` might provide better results.
+            enable (bool): Whether to enable uneven input detection or not. Pass
+                in ``enable=False`` to disable in cases where you know that
+                inputs are even across participating processes. Default is
+                ``True``.
+            throw_on_early_termination (bool): Whether to throw an error
+                or continue training when at least one rank has exhausted
+                inputs. If ``True``, will throw upon the first rank reaching end
+                of data. If ``False``, will continue training with a smaller
+                effective world size until all ranks are joined. Note that if
+                this flag is specified, then the flag
+                ``divide_by_initial_world_size`` would be ignored. Default
+                is ``False``.

+                             This function is called once the bucket is ready. The
+                             hook can perform whatever processing is needed and return
+                             a Future indicating completion of any async work (ex: allreduce).
+                             If the hook doesn't perform any communication, it still
+                             must return a completed Future. The Future should hold the
+                             new value of grad bucket's tensors. Once a bucket is ready,
+                             c10d reducer would call this hook and use the tensors returned
+                             by the Future and copy grads to individual parameters.
+                             Note that the future's return type must be a single tensor.
+
+                             We also provide an API called ``get_future`` to retrieve a
+                             Future associated with the completion of ``c10d.ProcessGroup.Work``.
+                             ``get_future`` is currently supported for NCCL and also supported for most
+                             operations on GLOO and MPI, except for peer to peer operations (send/recv).
+

+    r"""
+    Return a forward function for a module, populating grad_sample with per sample gradients on backward invocation.
+
+    Args:
+        module: The ``nn.Module`` to get per sample gradients with respect to. All trainable
+          parameters will compute per sample gradients, located in a ``grad_sample``
+          field when ``backward`` is invoked
+        batch_size: The batch size of the input. If None is passed, all tensor arguments in args and kwargs must have
+          the same batch size, which is the size of the first dimension. Otherwise, it must be passed manually.
+          Default: None
+        loss_reduction: Indicates if the loss reduction (for aggregating the gradients) is a sum or a mean operation. If
+          "mean", per sample gradients will be scaled by the batch size to offset the crossbatch interaction from
+          running mean across a batch. Must be "mean" or "sum". Default: "sum"
+        batch_first: Indicates if the batch dimension is the first dimension. If True, the batch dimension is the first
+          dimension. If False, it's the second dimension. Default: True.
+
+    Examples::
+        >>> # xdoctest: +SKIP
+        >>> model = nn.Linear(4, 3)
+        >>> batched_input = torch.randn(5, 4)  # batch size of 5
+        >>> res = call_for_per_sample_grads(model)(batched_input).sum()
+        >>> res.backward()
+        >>> assert model.weight.shape == (3, 4)
+        >>> assert model.weight.grad_sample.shape == (5, 3, 4)
+        >>> assert model.weight.grad is None
+        >>> assert model.bias.shape == (3,)
+        >>> assert model.bias.grad_sample.shape == (5, 3)
+        >>> assert model.bias.grad is None
+
+    An example using "mean" loss reduction. The grad_sample fields will be scaled by batch_size from what they would be
+    if we ran the same code with loss_reduction="sum". This is because the mean at the end will scale all
+    grad_outputs by 1 / batch_size from cross batch interaction.
+        >>> model = nn.Linear(4, 3)
+        >>> batched_input = torch.randn(5, 4)  # batch size of 5
+        >>> res = call_for_per_sample_grads(model, 5, loss_reduction="mean")(
+        ...     batched_input
+        ... ).mean()
+        >>> res.backward()
+
+    Note::
+        Does not work with any `nn.RNN`, including `nn.GRU` or `nn.LSTM`. Please use custom
+        rewrites that wrap an `nn.Linear` module. See Opacus for an example

+        Hence following convolutions will not need to permute its input tensor.
+
+        In case where a channels last incompatible layer is between convolution

+
+    Letting :math:`\mathbb{K}` be :math:`\mathbb{R}` or :math:`\mathbb{C}`, the parametrized
+    matrix :math:`Q \in \mathbb{K}^{m \times n}` is **orthogonal** as
+
+    .. math::
+
+        \begin{align*}
+            Q^{\text{H}}Q &= \mathrm{I}_n \mathrlap{\qquad \text{if }m \geq n}\\
+            QQ^{\text{H}} &= \mathrm{I}_m \mathrlap{\qquad \text{if }m < n}
+        \end{align*}
+
+    where :math:`Q^{\text{H}}` is the conjugate transpose when :math:`Q` is complex
+    and the transpose when :math:`Q` is real-valued, and
+    :math:`\mathrm{I}_n` is the `n`-dimensional identity matrix.
+    In plain words, :math:`Q` will have orthonormal columns whenever :math:`m \geq n`
+    and orthonormal rows otherwise.
+
+    If the tensor has more than two dimensions, we consider it as a batch of matrices of shape `(..., m, n)`.
+
+    The matrix :math:`Q` may be parametrized via three different ``orthogonal_map`` in terms of the original tensor:
+
+    - ``"matrix_exp"``/``"cayley"``:
+      the :func:`~torch.matrix_exp` :math:`Q = \exp(A)` and the `Cayley map`_
+      :math:`Q = (\mathrm{I}_n + A/2)(\mathrm{I}_n - A/2)^{-1}` are applied to a skew-symmetric
+      :math:`A` to give an orthogonal matrix.
+    - ``"householder"``: computes a product of Householder reflectors
+      (:func:`~torch.linalg.householder_product`).
+
+    ``"matrix_exp"``/``"cayley"`` often make the parametrized weight converge faster than
+    ``"householder"``, but they are slower to compute for very thin or very wide matrices.
+
+    If ``use_trivialization=True`` (default), the parametrization implements the "Dynamic Trivialization Framework",
+    where an extra matrix :math:`B \in \mathbb{K}^{n \times n}` is stored under
+    ``module.parametrizations.weight[0].base``. This helps the
+    convergence of the parametrized layer at the expense of some extra memory use.
+    See `Trivializations for Gradient-Based Optimization on Manifolds`_ .
+
+    Initial value of :math:`Q`:
+    If the original tensor is not parametrized and ``use_trivialization=True`` (default), the initial value
+    of :math:`Q` is that of the original tensor if it is orthogonal (or unitary in the complex case)
+    and it is orthogonalized via the QR decomposition otherwise (see :func:`torch.linalg.qr`).
+    Same happens when it is not parametrized and ``orthogonal_map="householder"`` even when ``use_trivialization=False``.
+    Otherwise, the initial value is the result of the composition of all the registered
+    parametrizations applied to the original tensor.
+
+    .. note::
+        This function is implemented using the parametrization functionality
+        in :func:`~torch.nn.utils.parametrize.register_parametrization`.

+        #     because in `DataParallel` forward, the vectors (being buffers) are
+        #     broadcast from the parallelized module to each module replica,
+        #     which is a new module object created on the fly. And each replica
+        #     runs its own spectral norm power iteration. So simply assigning
+        #     the updated vectors to the module this function runs on will cause
+        #     the update to be lost forever. And the next time the parallelized
+        #     module is replicated, the same randomly initialized vectors are
+        #     broadcast and used!
+        #
+        #     Therefore, to make the change propagate back, we rely on two
+        #     important behaviors (also enforced via tests):
+        #       1. `DataParallel` doesn't clone storage if the broadcast tensor
+        #          is already on correct device; and it makes sure that the
+        #          parallelized module is already on `device[0]`.
+        #       2. If the out tensor in `out=` kwarg has correct shape, it will
+        #          just fill in the values.
+        #     Therefore, since the same power iteration is performed on all
+        #     devices, simply updating the tensors in-place will make sure that
+        #     the module replica on `device[0]` will update the _u vector on the
+        #     parallelized module (by shared storage).
+        #
+        #    However, after we update `u` and `v` in-place, we need to **clone**
+        #    them before using them to normalize the weight. This is to support
+        #    backproping through two forward passes, e.g., the common pattern in
+        #    GAN training: loss = D(real) - D(fake). Otherwise, engine will

+    r"""Register a parametrization to a tensor in a module.
+
+    Assume that ``tensor_name="weight"`` for simplicity. When accessing ``module.weight``,
+    the module will return the parametrized version ``parametrization(module.weight)``.
+    If the original tensor requires a gradient, the backward pass will differentiate
+    through :attr:`parametrization`, and the optimizer will update the tensor accordingly.
+
+    The first time that a module registers a parametrization, this function will add an attribute
+    ``parametrizations`` to the module of type :class:`~ParametrizationList`.
+
+    The list of parametrizations on the tensor ``weight`` will be accessible under
+    ``module.parametrizations.weight``.
+
+    The original tensor will be accessible under
+    ``module.parametrizations.weight.original``.
+
+    Parametrizations may be concatenated by registering several parametrizations
+    on the same attribute.
+
+    The training mode of a registered parametrization is updated on registration
+    to match the training mode of the host module
+
+    Parametrized parameters and buffers have an inbuilt caching system that can be activated
+    using the context manager :func:`cached`.
+
+    A :attr:`parametrization` may optionally implement a method with signature
+
+    .. code-block:: python
+
+        def right_inverse(self, X: Tensor) -> Union[Tensor, Sequence[Tensor]]
+
+    This method is called on the unparametrized tensor when the first parametrization
+    is registered to compute the initial value of the original tensor.
+    If this method is not implemented, the original tensor will be just the unparametrized tensor.
+
+    If all the parametrizations registered on a tensor implement `right_inverse` it is possible
+    to initialize a parametrized tensor by assigning to it, as shown in the example below.
+
+    It is possible for the first parametrization to depend on several inputs.
+    This may be implemented returning a tuple of tensors from ``right_inverse``
+    (see the example implementation of a ``RankOne`` parametrization below).
+
+    In this case, the unconstrained tensors are also located under ``module.parametrizations.weight``
+    with names ``original0``, ``original1``,...
+
+    .. note::
+
+        If unsafe=False (default) both the forward and right_inverse methods will be called
+        once to perform a number of consistency checks.
+        If unsafe=True, then right_inverse will be called if the tensor is not parametrized,
+        and nothing will be called otherwise.
+
+    .. note::
+
+        In most situations, ``right_inverse`` will be a function such that
+        ``forward(right_inverse(X)) == X`` (see
+        `right inverse <https://en.wikipedia.org/wiki/Inverse_function#Right_inverses>`_).
+        Sometimes, when the parametrization is not surjective, it may be reasonable
+        to relax this.
+
+    .. warning::
+
+        If a parametrization depends on several inputs, :func:`~register_parametrization`
+        will register a number of new parameters. If such parametrization is registered
+        after the optimizer is created, these new parameters will need to be added manually
+        to the optimizer. See :meth:`torch.Optimizer.add_param_group`.
+
+    Args:
+        module (nn.Module): module on which to register the parametrization
+        tensor_name (str): name of the parameter or buffer on which to register

+        #     updated in power iteration **in-place**. This is very important
+        #     because in `DataParallel` forward, the vectors (being buffers) are
+        #     broadcast from the parallelized module to each module replica,
+        #     which is a new module object created on the fly. And each replica
+        #     runs its own spectral norm power iteration. So simply assigning
+        #     the updated vectors to the module this function runs on will cause
+        #     the update to be lost forever. And the next time the parallelized
+        #     module is replicated, the same randomly initialized vectors are
+        #     broadcast and used!
+        #
+        #     Therefore, to make the change propagate back, we rely on two
+        #     important behaviors (also enforced via tests):
+        #       1. `DataParallel` doesn't clone storage if the broadcast tensor
+        #          is already on correct device; and it makes sure that the
+        #          parallelized module is already on `device[0]`.
+        #       2. If the out tensor in `out=` kwarg has correct shape, it will
+        #          just fill in the values.
+        #     Therefore, since the same power iteration is performed on all
+        #     devices, simply updating the tensors in-place will make sure that
+        #     the module replica on `device[0]` will update the _u vector on the
+        #     parallelized module (by shared storage).
+        #
+        #    However, after we update `u` and `v` in-place, we need to **clone**
+        #    them before using them to normalize the weight. This is to support
+        #    backproping through two forward passes, e.g., the common pattern in
+        #    GAN training: loss = D(real) - D(fake). Otherwise, engine will

+
+    Weight normalization is a reparameterization that decouples the magnitude
+    of a weight tensor from its direction. This replaces the parameter specified
+    by :attr:`name` (e.g. ``'weight'``) with two parameters: one specifying the magnitude
+    (e.g. ``'weight_g'``) and one specifying the direction (e.g. ``'weight_v'``).
+    Weight normalization is implemented via a hook that recomputes the weight
+    tensor from the magnitude and direction before every :meth:`~Module.forward`
+    call.
+
+    By default, with ``dim=0``, the norm is computed independently per output
+    channel/plane. To compute a norm over the entire weight tensor, use
+    ``dim=None``.
+
+    See https://arxiv.org/abs/1602.07868
+
+    .. warning::
+
+        This function is deprecated.  Use :func:`torch.nn.utils.parametrizations.weight_norm`
+        which uses the modern parametrization API.  The new ``weight_norm`` is compatible
+        with ``state_dict`` generated from old ``weight_norm``.
+
+        Migration guide:
+
+        * The magnitude (``weight_g``) and direction (``weight_v``) are now expressed
+          as ``parametrizations.weight.original0`` and ``parametrizations.weight.original1``
+          respectively.  If this is bothering you, please comment on
+          https://github.com/pytorch/pytorch/issues/102999
+
+        * To remove the weight normalization reparametrization, use
+          :func:`torch.nn.utils.parametrize.remove_parametrizations`.
+
+        * The weight is no longer recomputed once at module forward; instead, it will
+          be recomputed on every access.  To restore the old behavior, use
+          :func:`torch.nn.utils.parametrize.cached` before invoking the module

+
+    Setting ``dynamo=True`` enables the new ONNX export logic
+    which is based on :class:`torch.export.ExportedProgram` and a more modern
+    set of translation logic. This is the recommended and default way to export models
+    to ONNX.
+
+    When ``dynamo=True``:
+
+    The exporter tries the following strategies to get an ExportedProgram for conversion to ONNX.
+
+    #. If the model is already an ExportedProgram, it will be used as-is.
+    #. Use :func:`torch.export.export` and set ``strict=False``.
+    #. Use :func:`torch.export.export` and set ``strict=True``.
+
+    Args:
+        model: The model to be exported.
+        args: Example positional inputs. Any non-Tensor arguments will be hard-coded into the
+            exported model; any Tensor arguments will become inputs of the exported model,
+            in the order they occur in the tuple.
+        f: Path to the output ONNX model file. E.g. "model.onnx". This argument is kept for
+            backward compatibility. It is recommended to leave unspecified (None)
+            and use the returned :class:`torch.onnx.ONNXProgram` to serialize the model
+            to a file instead.
+        kwargs: Optional example keyword inputs.
+        verbose: Whether to enable verbose logging.
+        input_names: names to assign to the input nodes of the graph, in order.
+        output_names: names to assign to the output nodes of the graph, in order.
+        opset_version: The version of the
+            `default (ai.onnx) opset <https://github.com/onnx/onnx/blob/master/docs/Operators.md>`_
+            to target. You should set ``opset_version`` according to the supported opset versions
+            of the runtime backend or compiler you want to run the exported model with.
+            Leave as default (``None``) to use the recommended version, or refer to
+            the ONNX operators documentation for more information.
+        dynamo: Whether to export the model with ``torch.export`` ExportedProgram instead of TorchScript.
+        external_data: Whether to save the model weights as an external data file.
+            This is required for models with large weights that exceed the ONNX file size limit (2GB).
+            When False, the weights are saved in the ONNX file with the model architecture.
+        dynamic_shapes: A dictionary or a tuple of dynamic shapes for the model inputs. Refer to
+            :func:`torch.export.export` for more details. This is only used (and preferred) when dynamo is True.
+            Note that dynamic_shapes is designed to be used when the model is exported with dynamo=True, while
+            dynamic_axes is used when dynamo=False.
+        custom_translation_table: A dictionary of custom decompositions for operators in the model.
+            The dictionary should have the callable target in the fx Node as the key (e.g. ``torch.ops.aten.stft.default``),
+            and the value should be a function that builds that graph using ONNX Script. This option
+            is only valid when dynamo is True.
+        report: Whether to generate a markdown report for the export process. This option
+            is only valid when dynamo is True.
+        optimize: Whether to optimize the exported model. This option
+            is only valid when dynamo is True. Default is True.
+        verify: Whether to verify the exported model using ONNX Runtime. This option
+            is only valid when dynamo is True.
+        profile: Whether to profile the export process. This option
+            is only valid when dynamo is True.
+        dump_exported_program: Whether to dump the :class:`torch.export.ExportedProgram` to a file.
+            This is useful for debugging the exporter. This option is only valid when dynamo is True.
+        artifacts_dir: The directory to save the debugging artifacts like the report and the serialized
+            exported program. This option is only valid when dynamo is True.
+        fallback: Whether to fallback to the TorchScript exporter if the dynamo exporter fails.
+            This option is only valid when dynamo is True. When fallback is enabled, It is
+            recommended to set dynamic_axes even when dynamic_shapes is provided.
+        export_params: **When ``f`` is specified**: If false, parameters (weights) will not be exported.
+
+            You can also leave it unspecified and use the returned :class:`torch.onnx.ONNXProgram`
+            to control how initializers are treated when serializing the model.
+        keep_initializers_as_inputs: **When ``f`` is specified**: If True, all the
+            initializers (typically corresponding to model weights) in the
+            exported graph will also be added as inputs to the graph. If False,
+            then initializers are not added as inputs to the graph, and only
+            the user inputs are added as inputs.
+
+            Set this to True if you intend to supply model weights at runtime.
+            Set it to False if the weights are static to allow for better optimizations
+            (e.g. constant folding) by backends/runtimes.
+
+            You can also leave it unspecified and use the returned :class:`torch.onnx.ONNXProgram`
+            to control how initializers are treated when serializing the model.
+        dynamic_axes:
+            Prefer specifying ``dynamic_shapes`` when ``dynamo=True`` and when ``fallback``
+            is not enabled.
+
+            By default the exported model will have the shapes of all input and output tensors
+            set to exactly match those given in ``args``. To specify axes of tensors as
+            dynamic (i.e. known only at run-time), set ``dynamic_axes`` to a dict with schema:
+
+            * KEY (str): an input or output name. Each name must also be provided in ``input_names`` or
+                ``output_names``.
+            * VALUE (dict or list): If a dict, keys are axis indices and values are axis names. If a
+                list, each element is an axis index.
+

+
+                class SumModule(torch.nn.Module):
+                    def forward(self, x):

+    Methods in the `Transform` class can be overridden to customize the behavior of the model.
+    This pattern can be useful for many things, including writing code transformations as well as analysis passes.

+    are needed to reconcile :attr:`ONNXProgram.model_proto`.

+
+    Args:
+        graph_context: The Torch Graph or Block.
+        opname: The ONNX operator name, e.g., `Abs` or `Add`, or an operator qualified
+            with a namespace, e.g., `aten::add`.
+        args: The inputs to the operator; usually provided
+            as arguments to the `symbolic` definition.
+        outputs: The number of outputs this operator returns.
+            By default an operator is assumed to return a single output.
+            If `outputs` is greater than one, this functions returns a tuple
+            of output `Value`, representing each output of the ONNX operator

+            the `alpha` attribute with type `f`.  The valid type specifiers are
+            `f` (float), `i` (int), `s` (string) or `t` (Tensor).  An attribute
+            specified with type float accepts either a single float, or a
+            list of floats (e.g., you would say `dims_i` for a `dims` attribute
+            that takes a list of integers).

+        training:

+                `ATen <https://pytorch.org/cppdocs/#aten>`_ is PyTorch's built-in tensor library, so
+                this instructs the runtime to use PyTorch's implementation of these ops.
+

+
+                    Models exported this way are probably runnable only by Caffe2.
+
+                    This may be useful if the numeric differences in implementations of operators are
+                    causing large differences in behavior between PyTorch and Caffe2 (which is more
+                    common on untrained models).
+
+            * ``OperatorExportTypes.ONNX_ATEN_FALLBACK``: Try to export each ATen op
+                (in the TorchScript namespace "aten") as a regular ONNX op. If we are unable to do so
+                (e.g. because support has not been added to convert a particular torch op to ONNX),
+                fall back to exporting an ATen op. See documentation on OperatorExportTypes.ONNX_ATEN for
+                context.
+                For example::

+            to target. Must be >= 7.
+        do_constant_folding: Apply the constant-folding optimization.
+            Constant-folding will replace some of the ops that have all constant inputs
+            with pre-computed constant nodes.
+        dynamic_axes:
+
+            By default the exported model will have the shapes of all input and output tensors
+            set to exactly match those given in ``args``. To specify axes of tensors as
+            dynamic (i.e. known only at run-time), set ``dynamic_axes`` to a dict with schema:
+
+            * KEY (str): an input or output name. Each name must also be provided in ``input_names`` or
+                ``output_names``.
+            * VALUE (dict or list): If a dict, keys are axis indices and values are axis names. If a
+                list, each element is an axis index.

+
+        keep_initializers_as_inputs: If True, all the
+            initializers (typically corresponding to parameters) in the
+            exported graph will also be added as inputs to the graph. If False,
+            then initializers are not added as inputs to the graph, and only
+            the non-parameter inputs are added as inputs.
+            This may allow for better optimizations (e.g. constant folding) by
+            backends/runtimes.
+
+            If True, `deduplicate_initializers` pass will not be executed. This means
+            initializers with duplicated values will not be deduplicated and
+            will be treated as distinct inputs to the graph. This allows different
+            input initializers to be supplied at the runtime following export.
+
+            If ``opset_version < 9``, initializers MUST be part of graph
+            inputs and this argument will be ignored and the behavior will be
+            equivalent to setting this argument to True.
+
+        custom_opsets (dict[str, int], default empty dict): A dict with schema:

+            * VALUE (int): opset version
+
+            If a custom opset is referenced by ``model`` but not mentioned in this dictionary,
+            the opset version is set to 1. Only custom opset domain name and version should be
+            indicated through this argument.
+
+        export_modules_as_functions: Flag to enable
+            exporting all ``nn.Module`` forward calls as local functions in ONNX. Or a set to indicate the
+            particular types of modules to export as local functions in ONNX.
+            This feature requires ``opset_version`` >= 15, otherwise the export will fail. This is because
+            ``opset_version`` < 15 implies IR version < 8, which means no local function support.
+            Module variables will be exported as function attributes. There are two categories of function
+            attributes.
+
+            1. Annotated attributes: class variables that have type annotations via
+            `PEP 526-style <https://www.python.org/dev/peps/pep-0526/#class-and-instance-variable-annotations>`_
+            will be exported as attributes.
+            Annotated attributes are not used inside the subgraph of ONNX local function because
+            they are not created by PyTorch JIT tracing, but they may be used by consumers
+            to determine whether or not to replace the function with a particular fused kernel.
+
+            2. Inferred attributes: variables that are used by operators inside the module. Attribute names
+            will have prefix "inferred::". This is to differentiate from predefined attributes retrieved from
+            python module annotations. Inferred attributes are used inside the subgraph of ONNX local function.
+
+            * ``False`` (default): export ``nn.Module`` forward calls as fine grained nodes.
+            * ``True``: export all ``nn.Module`` forward calls as local function nodes.
+            * Set of type of nn.Module: export ``nn.Module`` forward calls as local function nodes,
+                only if the type of the ``nn.Module`` is found in the set.
+
+        autograd_inlining: Flag used to control whether to inline autograd functions.
+            Refer to https://github.com/pytorch/pytorch/pull/74765 for more details.

+            which is usually the case with exporting ScriptModules. Default to True.
+        check_shape: Whether to check the shapes between PyTorch and ONNX Runtime outputs
+            are exactly the same. Set this to False to allow output shape broadcasting.

+            are consistent. Default to True.
+        backend: ONNX backend for verification. Default to OnnxBackend.ONNX_RUNTIME_CPU.
+        rtol: relative tolerance in comparison between ONNX and PyTorch outputs.
+        atol: absolute tolerance in comparison between ONNX and PyTorch outputs.
+        remained_onnx_input_idx: If provided, only the specified inputs will be passed
+            to the ONNX model. Supply a list when there are unused inputs in the model.
+            Since unused inputs will be removed in the exported ONNX model, supplying

+
+    RotaryEmbedding is the implementation of rotary positional embeddings (RoPE) based on the paper https://arxiv.org/pdf/2104.09864.
+    The key advantage of RoPE is that it allows the model to understand both the absolute position of a token and the relative distances
+    between tokens. This is achieved through a rotational mechanism where the extent of rotation is computed based on the token's absolute position (position_ids).
+
+    The rotational mechanism is defined by sine and cosine functions that are used to represent the rotation angles.
+    For each token in the sequence, its positional embedding is computed by rotating its embedding vector. This is done by splitting the
+    embedding vector either into two halves or interleaving every alternate token and applying the rotation matrix to each half of the embedding vector.
+    The rotation matrix is parameterized by the token's position in the sequence. The rotated halves of the embedding vector are concatenated
+    to form the final positional embedding for each token. The rotated positional embeddings are used in the self-attention mechanism.
+    The rotation ensures that the model captures both absolute and relative positional information.
+
+    Args:
+        X: The input tensor representing the token embeddings. 4D tensor with
+            shape `(batch_size, num_heads, sequence_length, head_size)` or 3D tensor
+            with shape `(batch_size, sequence_length, hidden_size)`. For cases with
+            a 4D input tensor, `head_size` has to be even. For cases with a 3D input
+            tensor, `num_heads` attribute must be provided and `hidden_size` must
+            be an even multiple of `num_heads` where `hidden_size = num_heads * head_size`
+        cos_cache: The cosine values for the rotation. 2D tensor with shape `(max_position_id_plus_1, head_size / 2)`
+            for full rotation or `(max_position_id_plus_1, rotary_embedding_dim / 2)`
+            for partial rotation when `position_ids` are provided. 3D tensor with shape
+            `(batch_size, sequence_length, head_size / 2)` for full rotation or
+            `(batch_size, sequence_length, rotary_embedding_dim / 2)` for partial
+            rotation when `position_ids` are not provided. `max_position_id_plus_1`
+            is a parameter to the model.
+        sin_cache: The sine values for the rotation. 2D tensor with shape `(max_position_id_plus_1, head_size / 2)`
+            for full rotation or `(max_position_id_plus_1, rotary_embedding_dim / 2)`

+            when `position_ids` are not provided. `max_position_id_plus_1` is a parameter
+            to the model.
+        position_ids: The position indices for the tokens. 2D tensor with shape
+            `(batch_size, sequence_length)`.
+        interleaved: Rotate using interleaved pattern. Default value is 0 (False).

+
+    This operator covers self and cross variants of the attention operation based on sequence lengths of K, Q and V.
+

+
+    1. If ``is_causal`` is set to `1`, the attention masking is a lower triangular matrix when the mask is a square matrix. The attention masking has the form of the upper left causal bias due to the alignment.

+"""Implementation of symbolic FX ops to represent arbitrary ONNX ops.
+
+This module provides a way to create symbolic FX operators that can represent
+arbitrary ONNX operators.
+
+The operators are called "symbolic" because they don't do any actual computation
+but instead serve as placeholders in the computation graph.
+
+Each implementation contains two parts: A "real" implementation that produce all
+zeros based on the input shape and dtype, and a "fake" implementation that does more
+or less the same thing but is required by the `torch.library.custom_op` interface.

+        lr (float, Tensor, optional): unlike other optimizers, Adafactor does not require a
+            learning rate, and Noam Shazeer and Mitchell Stern do not use lr at all.
+            Deviating from the paper, this implementation uses lr for applying weight
+            decay and as the maximum value for relative step size rho_t. Note that in
+            the paper, a constant of 0.01 is used as the maximum value for relative
+            step size, and so we set 0.01 as the default value. (default: 1e-2)
+        beta2_decay (float, optional): the decay rate of beta2. beta2 standardly refers
+            to the coefficient used for computing the running average of the gradient
+            squared. (default: -0.8)
+        eps (Tuple[float, float], optional): epsilon1 is the term added to the denominator
+            of the update calculation to improve numerical stability. This use of epsilon1
+            deviates from the algorithm written in the paper! See note below for more details.
+            epsilon2 is the term used to avoid having too small a weight update when applying
+            parameter scaling. (default: (None, 1e-3))
+        d (float, optional): the clipping threshold, used to avoid larger-than-desired
+            updates.
+        weight_decay (float, optional): weight decay coefficient (default: 1e-2)
+        foreach (bool, optional): whether foreach implementation of optimizer is used. Note
+            that the foreach implementation uses ~ sizeof(params) more peak memory than the
+            for-loop version due to the intermediates being a tensorlist vs just one tensor.
+            As Adafactor is commonly used when memory is prohibitive, Adafactor will default
+            to the slower single tensor for-loop implementation unless this flag is explicitly
+            True. This behavior is contrary to other optimizers, which will attempt defaulting
+            to foreach on CUDA for faster runtime. (default: None)
+        {_maximize_doc}"""
+    + r"""
+    .. Note::
+        The implementation of Adafactor subtly differs from Noam Shazeer and Mitchell Stern
+        and implementations in some other frameworks with its use of learning rate and
+        :math:`\epsilon_1`.
+
+        Regarding the learning rate hyperparameter: Noam Shazeer and Mitchell Stern do not
+        use lr at all, as the stated algorithm uses :math:`\rho_t` and update clipping to
+        affect the step size.
+
+        This implementation allows `lr` to influence the maximum value for :math:`\rho_t`:
+
+        .. math::
+            \begin{aligned}
+                &\hspace{5mm}\rho_t \leftarrow min(lr, \frac{1}{\sqrt{t}})
+            \end{aligned}
+
+        This differs from Noam Shazeer and Mitchell Stern, who use a constant of 0.01 as
+        the maximum value of :math:`\rho_t`
+
+        .. math::
+            \begin{aligned}
+                &\hspace{5mm}\rho_t \leftarrow min(0.01, \frac{1}{\sqrt{t}})
+            \end{aligned}
+
+        Noam Shazeer and Mitchell Stern do not enforce an opinion on how weight decay should
+        be computed, and so we use the learning rate as a coefficient for decoupled weight
+        decay, similar to what is suggested in `Decoupled Weight Decay Regularization`_.
+
+        Regarding the use of :math:`\epsilon_1`: The implementation attempts to replicate the
+        presumed intention of Noam Shazeer and Mitchell Stern to use :math:`\epsilon_1` as
+        a stabilizing term when the squared gradient becomes small.
+
+        This stabilization can be written as
+
+        .. math::
+            \begin{aligned}
+                &\hspace{5mm}R_t \leftarrow \widehat{\beta}_{2_t}R_{t-1}+
+                    (1-\widehat{\beta}_{2_t})(G_t \odot G_t + 1_n \cdot 1^\top_m) \cdot 1_m          \\
+                &\hspace{5mm}C_t \leftarrow \widehat{\beta}_{2_t}C_{t-1}+
+                    (1-\widehat{\beta}_{2_t}) 1^\top_n \cdot (G_t \odot G_t + 1_n \cdot 1^\top_m)    \\
+                &\hspace{5mm}\widehat{V}_t \leftarrow
+                    \frac{R_t \cdot C_t}{max(1^\top_n \cdot R_t, \epsilon_1)}                        \\
+                &\hspace{5mm}U_t \leftarrow \frac{G_t}{max(\sqrt{\widehat{V}_t}, \epsilon_1)}        \\
+            \end{aligned}
+
+        where the row and column factors of gradient squared :math:`R_t` and :math:`C_t`
+        are left alone, and we apply :math:`\epsilon_1` at the final calculation of
+        the variance estimate :math:`\widehat{V}_t` and for the update :math:`U_t`.
+
+        This is in contrast to Noam Shazeer and Mitchell Stern and other frameworks which
+        apply :math:`\epsilon_1` to both row and column factors of the squared gradient, but
+        not in the calculations after:
+
+        .. math::
+            \begin{aligned}
+                &\hspace{5mm}R_t \leftarrow \widehat{\beta}_{2_t}R_{t-1}+
+                            (1-\widehat{\beta}_{2_t})(G_t \odot G_t + \epsilon_1 1_n \cdot 1^\top_m) \cdot 1_m          \\
+                &\hspace{5mm}C_t \leftarrow \widehat{\beta}_{2_t}C_{t-1}+
+                            (1-\widehat{\beta}_{2_t}) 1^\top_n \cdot (G_t \odot G_t + \epsilon_1 1_n \cdot 1^\top_m)    \\
+                &\hspace{5mm}\widehat{V}_t \leftarrow \frac{R_t \cdot C_t}{1^\top_n \cdot R_t}                          \\
+                &\hspace{5mm}U_t \leftarrow \frac{G_t}{\sqrt{\widehat{V}_t}}                                            \\
+            \end{aligned}
+
+        You may note that Noam Shazeer and Mitchell Stern describe using the sum of squared gradients,
+        while this implementation uses the mean instead. This choice is mathematically equivalent and
+        allows for greater numerical stability for large sums.

+    Here, :math:`\mathrm{NS}^{(a,b,c)}_{k}(\cdot;\varepsilon)` denotes :math:`k` iterations of the
+    Newton–Schulz orthogonalization operator parameterized by coefficients :math:`(a,b,c)`
+    with numerical stabilization :math:`\varepsilon`.
+
+    The purpose for :math:`\mathrm{AdjustLR}\!\big(\gamma;\ \mathrm{shape}\!\big(\theta_t \big) \big)`
+    is to make the orthogonalized update have a consistent :math:`RMS` across rectangular matrices.
+
+    Keller's original implementation scales the update by :math:`\sqrt{\max\!\left(1, \frac{A}{B}\right)}`,
+    where :math:`A` and :math:`B` are dimension of the matrix being optimized.
+
+    Moonshot's implementation also focuses on matching :math:`RMS` of AdamW. The adjustment is computed as:
+    :math:`\gamma \leftarrow {0.2}\gamma\,\sqrt{\max\!\left({A}, {B}\right)}`
+    The method is adopted from `Muon is Scalable for LLM Training`_. Research
+    results show that with this adjustment Muon can directly reuse the learning rate
+    and weight decay tuned for AdamW.
+
+    We provide two options for the learning rate adjustment: "original", which follows Keller's
+    implementation, and "match_rms_adamw", which refers to Moonshot's implementation. This gives users the
+    flexibility to choose between the two. If `adjust_lr_fn` is not specified, the default is "original".
+
+    For further details regarding the algorithm we refer to `Muon: An optimizer for hidden layers in neural networks`_
+    and `Muon is Scalable for LLM Training`_.

+        cooldown (int): Number of epochs to wait before resuming
+            normal operation after lr has been reduced. Default: 0.
+        min_lr (float or list): A scalar or a list of scalars. A
+            lower bound on the learning rate of all param groups
+            or each group respectively. Default: 0.
+        eps (float): Minimal decay applied to lr. If the difference

+class CyclicLR(LRScheduler):
+    r"""Sets the learning rate of each parameter group according to cyclical learning rate policy (CLR).
+
+    The policy cycles the learning rate between two boundaries with a constant frequency,
+    as detailed in the paper `Cyclical Learning Rates for Training Neural Networks`_.
+    The distance between the two boundaries can be scaled on a per-iteration
+    or per-cycle basis.
+
+    Cyclical learning rate policy changes the learning rate after every batch.
+    `step` should be called after a batch has been used for training.
+
+    This class has three built-in policies, as put forth in the paper:
+
+    * "triangular": A basic triangular cycle without amplitude scaling.
+    * "triangular2": A basic triangular cycle that scales initial amplitude by half each cycle.
+    * "exp_range": A cycle that scales initial amplitude by :math:`\text{gamma}^{\text{cycle iterations}}`
+      at each cycle iteration.
+
+    This implementation was adapted from the github repo: `bckenstler/CLR`_
+
+    Args:
+        optimizer (Optimizer): Wrapped optimizer.
+        base_lr (float or list): Initial learning rate which is the
+            lower boundary in the cycle for each parameter group.
+        max_lr (float or list): Upper learning rate boundaries in the cycle
+            for each parameter group. Functionally,
+            it defines the cycle amplitude (max_lr - base_lr).
+            The lr at any cycle is the sum of base_lr
+            and some scaling of the amplitude; therefore
+            max_lr may not actually be reached depending on
+            scaling function.
+        step_size_up (int): Number of training iterations in the
+            increasing half of a cycle. Default: 2000
+        step_size_down (int): Number of training iterations in the
+            decreasing half of a cycle. If step_size_down is None,
+            it is set to step_size_up. Default: None
+        mode (str): One of {triangular, triangular2, exp_range}.
+            Values correspond to policies detailed above.
+            If scale_fn is not None, this argument is ignored.
+            Default: 'triangular'
+        gamma (float): Constant in 'exp_range' scaling function:
+            gamma**(cycle iterations)
+            Default: 1.0
+        scale_fn (function): Custom scaling policy defined by a single
+            argument lambda function, where
+            0 <= scale_fn(x) <= 1 for all x >= 0.
+            If specified, then 'mode' is ignored.
+            Default: None
+        scale_mode (str): {'cycle', 'iterations'}.
+            Defines whether scale_fn is evaluated on
+            cycle number or cycle iterations (training
+            iterations since start of cycle).
+            Default: 'cycle'
+        cycle_momentum (bool): If ``True``, momentum is cycled inversely
+            to learning rate between 'base_momentum' and 'max_momentum'.
+            Default: True
+        base_momentum (float or list): Lower momentum boundaries in the cycle
+            for each parameter group. Note that momentum is cycled inversely
+            to learning rate; at the peak of a cycle, momentum is
+            'base_momentum' and learning rate is 'max_lr'.
+            Default: 0.8
+        max_momentum (float or list): Upper momentum boundaries in the cycle
+            for each parameter group. Functionally,
+            it defines the cycle amplitude (max_momentum - base_momentum).
+            The momentum at any cycle is the difference of max_momentum
+            and some scaling of the amplitude; therefore
+            base_momentum may not actually be reached depending on
+            scaling function. Note that momentum is cycled inversely
+            to learning rate; at the start of a cycle, momentum is 'max_momentum'
+            and learning rate is 'base_lr'
+            Default: 0.9
+        last_epoch (int): The index of the last batch. This parameter is used when
+            resuming a training job. Since `step()` should be invoked after each
+            batch instead of after each epoch, this number represents the total
+            number of *batches* computed, not the total number of epochs computed.
+            When last_epoch=-1, the schedule is started from the beginning.
+            Default: -1
+
+    Example:
+        >>> # xdoctest: +SKIP
+        >>> optimizer = torch.optim.SGD(model.parameters(), lr=0.1, momentum=0.9)
+        >>> scheduler = torch.optim.lr_scheduler.CyclicLR(

+    r"""Sets the learning rate of each parameter group according to the 1cycle learning rate policy.
+
+    The 1cycle policy anneals the learning rate from an initial learning rate to some maximum
+    learning rate and then from that maximum learning rate to some minimum learning rate much
+    lower than the initial learning rate.
+    This policy was initially described in the paper `Super-Convergence:
+    Very Fast Training of Neural Networks Using Large Learning Rates`_.
+
+    The 1cycle learning rate policy changes the learning rate after every batch.
+    `step` should be called after a batch has been used for training.
+
+    This scheduler is not chainable.
+
+    Note also that the total number of steps in the cycle can be determined in one
+    of two ways (listed in order of precedence):
+
+    #. A value for total_steps is explicitly provided.
+    #. A number of epochs (epochs) and a number of steps per epoch
+       (steps_per_epoch) are provided.
+       In this case, the number of total steps is inferred by
+       total_steps = epochs * steps_per_epoch
+
+    You must either provide a value for total_steps or provide a value for both
+    epochs and steps_per_epoch.
+
+    The default behaviour of this scheduler follows the fastai implementation of 1cycle, which
+    claims that "unpublished work has shown even better results by using only two phases". To
+    mimic the behaviour of the original paper instead, set ``three_phase=True``.
+
+    Args:
+        optimizer (Optimizer): Wrapped optimizer.
+        max_lr (float or list): Upper learning rate boundaries in the cycle
+            for each parameter group.
+        total_steps (int): The total number of steps in the cycle. Note that
+            if a value is not provided here, then it must be inferred by providing
+            a value for epochs and steps_per_epoch.
+            Default: None
+        epochs (int): The number of epochs to train for. This is used along
+            with steps_per_epoch in order to infer the total number of steps in the cycle
+            if a value for total_steps is not provided.
+            Default: None
+        steps_per_epoch (int): The number of steps per epoch to train for. This is
+            used along with epochs in order to infer the total number of steps in the
+            cycle if a value for total_steps is not provided.
+            Default: None
+        pct_start (float): The percentage of the cycle (in number of steps) spent
+            increasing the learning rate.
+            Default: 0.3
+        anneal_strategy (str): {'cos', 'linear'}
+            Specifies the annealing strategy: "cos" for cosine annealing, "linear" for
+            linear annealing.
+            Default: 'cos'
+        cycle_momentum (bool): If ``True``, momentum is cycled inversely
+            to learning rate between 'base_momentum' and 'max_momentum'.
+            Default: True
+        base_momentum (float or list): Lower momentum boundaries in the cycle
+            for each parameter group. Note that momentum is cycled inversely
+            to learning rate; at the peak of a cycle, momentum is
+            'base_momentum' and learning rate is 'max_lr'.
+            Default: 0.85
+        max_momentum (float or list): Upper momentum boundaries in the cycle
+            for each parameter group. Functionally,
+            it defines the cycle amplitude (max_momentum - base_momentum).
+            Note that momentum is cycled inversely
+            to learning rate; at the start of a cycle, momentum is 'max_momentum'
+            and learning rate is 'base_lr'
+            Default: 0.95
+        div_factor (float): Determines the initial learning rate via
+            initial_lr = max_lr/div_factor
+            Default: 25
+        final_div_factor (float): Determines the minimum learning rate via
+            min_lr = initial_lr/final_div_factor
+            Default: 1e4
+        three_phase (bool): If ``True``, use a third phase of the schedule to annihilate the
+            learning rate according to 'final_div_factor' instead of modifying the second
+            phase (the first two phases will be symmetrical about the step indicated by
+            'pct_start').
+        last_epoch (int): The index of the last batch. This parameter is used when
+            resuming a training job. Since `step()` should be invoked after each
+            batch instead of after each epoch, this number represents the total
+            number of *batches* computed, not the total number of epochs computed.
+            When last_epoch=-1, the schedule is started from the beginning.
+            Default: -1

+    .. note::
+        The implementation of SGD with Momentum/Nesterov subtly differs from
+        Sutskever et al. and implementations in some other frameworks.
+
+        Considering the specific case of Momentum, the update can be written as
+
+        .. math::
+            \begin{aligned}
+                v_{t+1} & = \mu * v_{t} + g_{t+1}, \\
+                p_{t+1} & = p_{t} - \text{lr} * v_{t+1},
+            \end{aligned}
+
+        where :math:`p`, :math:`g`, :math:`v` and :math:`\mu` denote the
+        parameters, gradient, velocity, and momentum respectively.
+
+        This is in contrast to Sutskever et al. and
+        other frameworks which employ an update of the form
+
+        .. math::
+            \begin{aligned}
+                v_{t+1} & = \mu * v_{t} + \text{lr} * g_{t+1}, \\
+                p_{t+1} & = p_{t} - v_{t+1}.
+            \end{aligned}
+
+        The Nesterov version is analogously modified.
+
+        Moreover, the initial value of the momentum buffer is set to the
+        gradient value at the first step. This is in contrast to some other
+        frameworks that initialize it to all zeros. One notable side effect
+        of this decision is that the first momentum value will not be scaled
+        by dampening. Dampening will be applied starting at the second step.

+SparseAdam.__doc__ = rf"""SparseAdam implements a masked version of the Adam algorithm
+    suitable for sparse gradients. Currently, due to implementation constraints (explained
+    below), SparseAdam is only intended for a narrow subset of use cases, specifically
+    parameters of a dense layout with gradients of a sparse layout. This occurs in a
+    special case where the module backwards produces grads already in a sparse layout.
+    One example NN module that behaves as such is ``nn.Embedding(sparse=True)``.
+
+    SparseAdam approximates the Adam algorithm by masking out the parameter and moment
+    updates corresponding to the zero values in the gradients. Whereas the Adam algorithm
+    will update the first moment, the second moment, and the parameters based on all values
+    of the gradients, SparseAdam only updates the moments and parameters corresponding
+    to the non-zero values of the gradients.
+
+    A simplified way of thinking about the `intended` implementation is as such:
+
+    1. Create a mask of the non-zero values in the sparse gradients. For example,
+       if your gradient looks like [0, 5, 0, 0, 9], the mask would be [0, 1, 0, 0, 1].
+    2. Apply this mask over the running moments and do computation on only the
+       non-zero values.
+    3. Apply this mask over the parameters and only apply an update on non-zero values.
+
+    In actuality, we use sparse layout Tensors to optimize this approximation, which means the
+    more gradients that are masked by not being materialized, the more performant the optimization.
+    Since we rely on using sparse layout tensors, we infer that any materialized value in the
+    sparse layout is non-zero and we do NOT actually verify that all values are not zero!
+    It is important to not conflate a semantically sparse tensor (a tensor where many
+    of its values are zeros) with a sparse layout tensor (a tensor where ``.is_sparse``
+    returns ``True``). The SparseAdam approximation is intended for `semantically` sparse
+    tensors and the sparse layout is only a implementation detail. A clearer implementation
+    would be to use MaskedTensors, but those are experimental.
+
+
+    .. note::
+
+        If you suspect your gradients are semantically sparse (but do not have sparse
+        layout), this variant may not be the best for you. Ideally, you want to avoid
+        materializing anything that is suspected to be sparse in the first place, since
+        needing to convert all your grads from dense layout to sparse layout may outweigh
+        the performance gain. Here, using Adam may be the best alternative, unless you
+        can easily rig up your module to output sparse grads similar to
+        ``nn.Embedding(sparse=True)``. If you insist on converting your grads, you can do
+        so by manually overriding your parameters' ``.grad`` fields with their sparse
+        equivalents before calling ``.step()``.

+
+    Stochastic Weight Averaging was proposed in `Averaging Weights Leads to
+    Wider Optima and Better Generalization`_ by Pavel Izmailov, Dmitrii
+    Podoprikhin, Timur Garipov, Dmitry Vetrov and Andrew Gordon Wilson
+    (UAI 2018).
+
+    Exponential Moving Average is a variation of `Polyak averaging`_,
+    but using exponential weights instead of equal weights across iterations.
+
+    AveragedModel class creates a copy of the provided module :attr:`model`
+    on the device :attr:`device` and allows to compute running averages of the
+    parameters of the :attr:`model`.
+
+    Args:
+        model (torch.nn.Module): model to use with SWA/EMA
+        device (torch.device, optional): if provided, the averaged model will be
+            stored on the :attr:`device`
+        avg_fn (function, optional): the averaging function used to update
+            parameters; the function must take in the current value of the
+            :class:`AveragedModel` parameter, the current value of :attr:`model`
+            parameter, and the number of models already averaged; if None,
+            an equally weighted average is used (default: None)
+        multi_avg_fn (function, optional): the averaging function used to update
+            parameters inplace; the function must take in the current values of the
+            :class:`AveragedModel` parameters as a list, the current values of :attr:`model`
+            parameters as a list, and the number of models already averaged; if None,
+            an equally weighted average is used (default: None)
+        use_buffers (bool): if ``True``, it will compute running averages for
+            both the parameters and the buffers of the model. (default: ``False``)
+
+    Example:
+        >>> # xdoctest: +SKIP("undefined variables")
+        >>> loader, optimizer, model, loss_fn = ...
+        >>> swa_model = torch.optim.swa_utils.AveragedModel(model)
+        >>> scheduler = torch.optim.lr_scheduler.CosineAnnealingLR(optimizer,
+        >>>                                     T_max=300)
+        >>> swa_start = 160
+        >>> swa_scheduler = SWALR(optimizer, swa_lr=0.05)
+        >>> for i in range(300):
+        >>>      for input, target in loader:
+        >>>          optimizer.zero_grad()
+        >>>          loss_fn(model(input), target).backward()
+        >>>          optimizer.step()
+        >>>      if i > swa_start:
+        >>>          swa_model.update_parameters(model)
+        >>>          swa_scheduler.step()
+        >>>      else:
+        >>>          scheduler.step()
+        >>>
+        >>> # Update bn statistics for the swa_model at the end
+        >>> torch.optim.swa_utils.update_bn(loader, swa_model)
+
+    You can also use custom averaging functions with the `avg_fn` or `multi_avg_fn` parameters.
+    If no averaging function is provided, the default is to compute
+    equally-weighted average of the weights (SWA).
+
+    Example:
+        >>> # xdoctest: +SKIP("undefined variables")
+        >>> # Compute exponential moving averages of the weights and buffers
+        >>> ema_model = torch.optim.swa_utils.AveragedModel(model,
+        >>>             torch.optim.swa_utils.get_ema_multi_avg_fn(0.9), use_buffers=True)
+
+    .. note::
+        When using SWA/EMA with models containing Batch Normalization you may
+        need to update the activation statistics for Batch Normalization.
+        This can be done either by using the :meth:`torch.optim.swa_utils.update_bn`
+        or by setting :attr:`use_buffers` to `True`. The first approach updates the
+        statistics in a post-training step by passing data through the model. The
+        second does it during the parameter update phase by averaging all buffers.
+        Empirical evidence has shown that updating the statistics in normalization
+        layers increases accuracy, but you may wish to empirically test which
+        approach yields the best results in your problem.
+
+    .. note::
+        :attr:`avg_fn` and `multi_avg_fn` are not saved in the :meth:`state_dict` of the model.
+
+    .. note::
+        When :meth:`update_parameters` is called for the first time (i.e.
+        :attr:`n_averaged` is `0`) the parameters of `model` are copied
+        to the parameters of :class:`AveragedModel`. For every subsequent
+        call of :meth:`update_parameters` the function `avg_fn` is used
+        to update the parameters.

+
+    A candidate is composed of a list of segments separated by ``separator``, e.g. "foo.bar.baz".
+
+    A pattern contains one or more segments. Segments can be:
+        - A literal string (e.g. "foo"), which matches exactly.
+        - A string containing a wildcard (e.g. "torch*", or "foo*baz*"). The wildcard matches
+          any string, including the empty string.
+        - A double wildcard ("**"). This matches against zero or more complete segments.
+
+    Examples:
+        ``torch.**``: matches ``torch`` and all its submodules, e.g. ``torch.nn`` and ``torch.nn.functional``.
+        ``torch.*``: matches ``torch.nn`` or ``torch.functional``, but not ``torch.nn.functional``.
+        ``torch*.**``: matches ``torch``, ``torchvision``, and all their submodules.
+
+    A candidates will match the ``GlobGroup`` if it matches any of the ``include`` patterns and
+    none of the ``exclude`` patterns.
+
+    Args:

+            each representing a pattern to be matched against. A candidate
+            will be excluded from matching if it matches *any* exclude pattern.
+        separator (str): A string that delimits segments in candidates and
+            patterns. By default this is "." which corresponds to how modules are

+    for the packaging of PyTorch model code and data so that it can be run
+    on a server or used in the future for transfer learning.
+
+    The code contained in packages is copied file-by-file from the original

+    within the package, except for modules explicitly listed as external using :meth:`extern`.
+    The file ``extern_modules`` in the zip archive lists all the modules that a package externally depends on.
+    This prevents "implicit" dependencies where the package runs locally because it is importing
+    a locally-installed package, but then fails when the package is copied to another machine.
+
+    When source code is added to the package, the exporter can optionally scan it
+    for further code dependencies (``dependencies=True``). It looks for import statements,

+        schedule (Callable): callable that takes step (int) as a single parameter and returns

+        on_trace_ready (Callable): callable that is called at each step when ``schedule``

+        record_shapes (bool): save information about operator's input shapes.

+        with_stack (bool): record source information (file and line number) for the ops.
+        with_flops (bool): use formula to estimate the FLOPs (floating point operations) of specific operators

+        experimental_config (_ExperimentalConfig) : A set of experimental options
+            used for Kineto library features. Note, backward compatibility is not guaranteed.

+            `PyTorch Execution Traces <https://arxiv.org/pdf/2305.14516.pdf>`__ offer a graph based
+            representation of AI/ML workloads and enable replay benchmarks, simulators, and emulators.
+            When this argument is included the observer start() and stop() will be called for the
+            same time window as PyTorch profiler. See the examples section below for a code sample.
+        acc_events (bool): Enable the accumulation of FunctionEvents across multiple profiling cycles
+        use_cuda (bool):

+                use ``activities`` instead.
+
+    .. note::
+        Use :func:`~torch.profiler.schedule` to generate the callable schedule.
+        Non-default schedules are useful when profiling long training jobs
+        and allow the user to obtain multiple traces at the different iterations
+        of the training process.
+        The default schedule simply records all the events continuously for the
+        duration of the context manager.
+
+    .. note::
+        Use :func:`~torch.profiler.tensorboard_trace_handler` to generate result files for TensorBoard:
+
+        ``on_trace_ready=torch.profiler.tensorboard_trace_handler(dir_name)``
+
+        After profiling, result files can be found in the specified directory. Use the command:
+
+        ``tensorboard --logdir dir_name``
+
+        to see the results in TensorBoard.
+        For more information, see
+        `PyTorch Profiler TensorBoard Plugin <https://github.com/pytorch/kineto/tree/master/tb_plugin>`__
+
+    .. note::
+        Enabling shape and stack tracing results in additional overhead.
+        When record_shapes=True is specified, profiler will temporarily hold references to the tensors;
+        that may further prevent certain optimizations that depend on the reference count and introduce
+        extra tensor copies.

+FindCUDAToolkit
+---------------
+
+.. versionadded:: 3.17
+
+This script locates the NVIDIA CUDA toolkit and the associated libraries, but
+does not require the ``CUDA`` language be enabled for a given project. This
+module does not search for the NVIDIA CUDA Samples.
+
+.. versionadded:: 3.19
+  QNX support.
+
+Search Behavior
+^^^^^^^^^^^^^^^
+
+The CUDA Toolkit search behavior uses the following order:
+
+1. If the ``CUDA`` language has been enabled we will use the directory
+   containing the compiler as the first search location for ``nvcc``.
+
+2. If the ``CUDAToolkit_ROOT`` cmake configuration variable (e.g.,
+   ``-DCUDAToolkit_ROOT=/some/path``) *or* environment variable is defined, it
+   will be searched.  If both an environment variable **and** a
+   configuration variable are specified, the *configuration* variable takes
+   precedence.
+
+   The directory specified here must be such that the executable ``nvcc`` or
+   the appropriate ``version.txt`` file can be found underneath the specified
+   directory.
+
+3. If the CUDA_PATH environment variable is defined, it will be searched
+   for ``nvcc``.
+
+4. The user's path is searched for ``nvcc`` using :command:`find_program`.  If
+   this is found, no subsequent search attempts are performed.  Users are
+   responsible for ensuring that the first ``nvcc`` to show up in the path is
+   the desired path in the event that multiple CUDA Toolkits are installed.
+
+5. On Unix systems, if the symbolic link ``/usr/local/cuda`` exists, this is
+   used.  No subsequent search attempts are performed.  No default symbolic link
+   location exists for the Windows platform.
+
+6. The platform specific default install locations are searched.  If exactly one
+   candidate is found, this is used.  The default CUDA Toolkit install locations
+   searched are:
+
+   +-------------+-------------------------------------------------------------+
+   | Platform    | Search Pattern                                              |
+   +=============+=============================================================+
+   | macOS       | ``/Developer/NVIDIA/CUDA-X.Y``                              |
+   +-------------+-------------------------------------------------------------+
+   | Other Unix  | ``/usr/local/cuda-X.Y``                                     |
+   +-------------+-------------------------------------------------------------+
+   | Windows     | ``C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\vX.Y`` |
+   +-------------+-------------------------------------------------------------+
+
+   Where ``X.Y`` would be a specific version of the CUDA Toolkit, such as
+   ``/usr/local/cuda-9.0`` or
+   ``C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0``
+
+   .. note::
+
+       When multiple CUDA Toolkits are installed in the default location of a
+       system(e.g., both ``/usr/local/cuda-9.0`` and ``/usr/local/cuda-10.0``
+       exist but the ``/usr/local/cuda`` symbolic link does **not** exist), this
+       package is marked as **not** found.
+
+       There are too many factors involved in making an automatic decision in
+       the presence of multiple CUDA Toolkits being installed.  In this
+       situation, users are encouraged to either (1) set ``CUDAToolkit_ROOT`` or
+       (2) ensure that the correct ``nvcc`` executable shows up in ``$PATH`` for
+       :command:`find_program` to find.
+
+Arguments
+^^^^^^^^^
+
+``[<version>]``
+    The ``[<version>]`` argument requests a version with which the package found
+    should be compatible. See :ref:`find_package version format <FIND_PACKAGE_VERSION_FORMAT>`
+    for more details.
+
+Options
+^^^^^^^
+
+``REQUIRED``
+    If specified, configuration will error if a suitable CUDA Toolkit is not
+    found.
+
+``QUIET``
+    If specified, the search for a suitable CUDA Toolkit will not produce any
+    messages.
+
+``EXACT``
+    If specified, the CUDA Toolkit is considered found only if the exact
+    ``VERSION`` specified is recovered.
+
+Imported targets
+^^^^^^^^^^^^^^^^
+
+An :ref:`imported target <Imported targets>` named ``CUDA::toolkit`` is provided.
+
+This module defines :prop_tgt:`IMPORTED` targets for each
+of the following libraries that are part of the CUDAToolkit:

+Result variables
+^^^^^^^^^^^^^^^^
+
+``CUDAToolkit_FOUND``
+    A boolean specifying whether or not the CUDA Toolkit was found.
+
+``CUDAToolkit_VERSION``
+    The exact version of the CUDA Toolkit found (as reported by
+    ``nvcc --version`` or ``version.txt``).
+
+``CUDAToolkit_VERSION_MAJOR``
+    The major version of the CUDA Toolkit.
+
+``CUDAToolkit_VERSION_MINOR``
+    The minor version of the CUDA Toolkit.
+
+``CUDAToolkit_VERSION_PATCH``
+    The patch version of the CUDA Toolkit.
+
+``CUDAToolkit_BIN_DIR``
+    The path to the CUDA Toolkit library directory that contains the CUDA
+    executable ``nvcc``.
+
+``CUDAToolkit_INCLUDE_DIRS``
+    The path to the CUDA Toolkit ``include`` folder containing the header files
+    required to compile a project linking against CUDA.
+
+``CUDAToolkit_LIBRARY_DIR``
+    The path to the CUDA Toolkit library directory that contains the CUDA
+    Runtime library ``cudart``.
+
+``CUDAToolkit_LIBRARY_ROOT``
+    .. versionadded:: 3.18
+
+    The path to the CUDA Toolkit directory containing the nvvm directory and
+    version.txt.
+
+``CUDAToolkit_TARGET_DIR``
+    The path to the CUDA Toolkit directory including the target architecture
+    when cross-compiling. When not cross-compiling this will be equivalent to
+    the parent directory of ``CUDAToolkit_BIN_DIR``.
+
+``CUDAToolkit_NVCC_EXECUTABLE``
+    The path to the NVIDIA CUDA compiler ``nvcc``.  Note that this path may
+    **not** be the same as
+    :variable:`CMAKE_CUDA_COMPILER <CMAKE_<LANG>_COMPILER>`.  ``nvcc`` must be
+    found to determine the CUDA Toolkit version as well as determining other
+    features of the Toolkit.  This variable is set for the convenience of
+    modules that depend on this one.

+# FindCUDA
+# --------
+#
+# .. note::
+#
+#   The FindCUDA module has been superseded by first-class support
+#   for the CUDA language in CMake.  It is no longer necessary to
+#   use this module or call ``find_package(CUDA)``.  This module
+#   now exists only for compatibility with projects that have not
+#   been ported.
+#
+#   Instead, list ``CUDA`` among the languages named in the top-level
+#   call to the :command:`project` command, or call the
+#   :command:`enable_language` command with ``CUDA``.
+#   Then one can add CUDA (``.cu``) sources to programs directly
+#   in calls to :command:`add_library` and :command:`add_executable`.
+#
+# Tools for building CUDA C files: libraries and build dependencies.
+#
+# This script locates the NVIDIA CUDA C tools.  It should work on Linux,
+# Windows, and macOS and should be reasonably up to date with CUDA C
+# releases.
+#
+# This script makes use of the standard :command:`find_package` arguments of
+# ``<VERSION>``, ``REQUIRED`` and ``QUIET``.  ``CUDA_FOUND`` will report if an
+# acceptable version of CUDA was found.
+#
+# The script will prompt the user to specify ``CUDA_TOOLKIT_ROOT_DIR`` if
+# the prefix cannot be determined by the location of nvcc in the system
+# path and ``REQUIRED`` is specified to :command:`find_package`.  To use
+# a different installed version of the toolkit set the environment variable
+# ``CUDA_BIN_PATH`` before running cmake (e.g.
+# ``CUDA_BIN_PATH=/usr/local/cuda1.0`` instead of the default
+# ``/usr/local/cuda``) or set ``CUDA_TOOLKIT_ROOT_DIR`` after configuring.  If
+# you change the value of ``CUDA_TOOLKIT_ROOT_DIR``, various components that
+# depend on the path will be relocated.
+#
+# It might be necessary to set ``CUDA_TOOLKIT_ROOT_DIR`` manually on certain
+# platforms, or to use a CUDA runtime not installed in the default
+# location.  In newer versions of the toolkit the CUDA library is
+# included with the graphics driver -- be sure that the driver version
+# matches what is needed by the CUDA runtime version.
+#
+# The following variables affect the behavior of the macros in the
+# script (in alphebetical order).  Note that any of these flags can be
+# changed multiple times in the same directory before calling
+# ``CUDA_ADD_EXECUTABLE``, ``CUDA_ADD_LIBRARY``, ``CUDA_COMPILE``,
+# ``CUDA_COMPILE_PTX``, ``CUDA_COMPILE_FATBIN``, ``CUDA_COMPILE_CUBIN``
+# or ``CUDA_WRAP_SRCS``::
+#
+#   CUDA_64_BIT_DEVICE_CODE (Default matches host bit size)
+#   -- Set to ON to compile for 64 bit device code, OFF for 32 bit device code.
+#      Note that making this different from the host code when generating object
+#      or C files from CUDA code just won't work, because size_t gets defined by
+#      nvcc in the generated source.  If you compile to PTX and then load the
+#      file yourself, you can mix bit sizes between device and host.
+#
+#   CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE (Default ON)
+#   -- Set to ON if you want the custom build rule to be attached to the source
+#      file in Visual Studio.  Turn OFF if you add the same cuda file to multiple
+#      targets.
+#
+#      This allows the user to build the target from the CUDA file; however, bad
+#      things can happen if the CUDA source file is added to multiple targets.
+#      When performing parallel builds it is possible for the custom build
+#      command to be run more than once and in parallel causing cryptic build
+#      errors.  VS runs the rules for every source file in the target, and a
+#      source can have only one rule no matter how many projects it is added to.
+#      When the rule is run from multiple targets race conditions can occur on
+#      the generated file.  Eventually everything will get built, but if the user
+#      is unaware of this behavior, there may be confusion.  It would be nice if
+#      this script could detect the reuse of source files across multiple targets
+#      and turn the option off for the user, but no good solution could be found.
+#
+#   CUDA_BUILD_CUBIN (Default OFF)
+#   -- Set to ON to enable and extra compilation pass with the -cubin option in
+#      Device mode. The output is parsed and register, shared memory usage is
+#      printed during build.
+#
+#   CUDA_BUILD_EMULATION (Default OFF for device mode)
+#   -- Set to ON for Emulation mode. -D_DEVICEEMU is defined for CUDA C files
+#      when CUDA_BUILD_EMULATION is TRUE.
+#
+#   CUDA_LINK_LIBRARIES_KEYWORD (Default "")
+#    -- The <PRIVATE|PUBLIC|INTERFACE> keyword to use for internal
+#       target_link_libraries calls. The default is to use no keyword which
+#       uses the old "plain" form of target_link_libraries. Note that is matters
+#       because whatever is used inside the FindCUDA module must also be used
+#       outside - the two forms of target_link_libraries cannot be mixed.
+#
+#   CUDA_GENERATED_OUTPUT_DIR (Default CMAKE_CURRENT_BINARY_DIR)
+#   -- Set to the path you wish to have the generated files placed.  If it is
+#      blank output files will be placed in CMAKE_CURRENT_BINARY_DIR.
+#      Intermediate files will always be placed in
+#      CMAKE_CURRENT_BINARY_DIR/CMakeFiles.
+#
+#   CUDA_HOST_COMPILATION_CPP (Default ON)
+#   -- Set to OFF for C compilation of host code.
+#
+#   CUDA_HOST_COMPILER (Default CMAKE_C_COMPILER)
+#   -- Set the host compiler to be used by nvcc.  Ignored if -ccbin or
+#      --compiler-bindir is already present in the CUDA_NVCC_FLAGS or
+#      CUDA_NVCC_FLAGS_<CONFIG> variables.  For Visual Studio targets,
+#      the host compiler is constructed with one or more visual studio macros
+#      such as $(VCInstallDir), that expands out to the path when
+#      the command is run from within VS.
+#      If the CUDAHOSTCXX environment variable is set it will
+#      be used as the default.
+#
+#   CUDA_NVCC_FLAGS
+#   CUDA_NVCC_FLAGS_<CONFIG>
+#   -- Additional NVCC command line arguments.  NOTE: multiple arguments must be
+#      semi-colon delimited (e.g. --compiler-options;-Wall)
+#
+#   CUDA_PROPAGATE_HOST_FLAGS (Default ON)
+#   -- Set to ON to propagate CMAKE_{C,CXX}_FLAGS and their configuration

+#      certain flags give nvcc problems, and this will help you turn the flag
+#      propagation off.  This does not affect the flags supplied directly to nvcc
+#      via CUDA_NVCC_FLAGS or through the OPTION flags specified through

+#
+#   CUDA_USE_STATIC_CUDA_RUNTIME (Default ON)

+# The script creates the following macros (in alphebetical order)::
+#
+#   CUDA_ADD_CUFFT_TO_TARGET( cuda_target )
+#   -- Adds the cufft library to the target (can be any target).  Handles whether
+#      you are in emulation mode or not.
+#
+#   CUDA_ADD_CUBLAS_TO_TARGET( cuda_target )

+#                        [WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
+#   -- Creates an executable "cuda_target" which is made up of the files
+#      specified.  All of the non CUDA C files are compiled using the standard
+#      build rules specified by CMAKE and the cuda files are compiled to object
+#      files using nvcc and the host compiler.  In addition CUDA_INCLUDE_DIRS is
+#      added automatically to include_directories().  Some standard CMake target
+#      calls can be used on the target after calling this macro
+#      (e.g. set_target_properties and target_link_libraries), but setting
+#      properties that adjust compilation flags will not affect code compiled by
+#      nvcc.  Such flags should be modified before calling CUDA_ADD_EXECUTABLE,
+#      CUDA_ADD_LIBRARY or CUDA_WRAP_SRCS.
+#
+#   CUDA_ADD_LIBRARY( cuda_target file0 file1 ...
+#                     [STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )

+#
+#   CUDA_BUILD_CLEAN_TARGET()
+#   -- Creates a convenience target that deletes all the dependency files
+#      generated.  You should make clean after running this target to ensure the

+#
+#   CUDA_COMPILE( generated_files file0 file1 ... [STATIC | SHARED | MODULE]
+#                 [OPTIONS ...] )
+#   -- Returns a list of generated files from the input source files to be used

+#      compilation as specified by object_files.  If the object_files list is
+#      empty, then output_file_var will be empty.  This function is called
+#      automatically for CUDA_ADD_LIBRARY and CUDA_ADD_EXECUTABLE.  Note that
+#      this is a function and not a macro.
+#
+#   CUDA_INCLUDE_DIRECTORIES( path0 path1 ... )
+#   -- Sets the directories that should be passed to nvcc
+#      (e.g. nvcc -Ipath0 -Ipath1 ... ). These paths usually contain other .cu
+#      files.
+#
+#
+#   CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS( output_file_var cuda_target
+#                                            nvcc_flags object_files)
+#   -- Generates the link object required by separable compilation from the given
+#      object files.  This is called automatically for CUDA_ADD_EXECUTABLE and
+#      CUDA_ADD_LIBRARY, but can be called manually when using CUDA_WRAP_SRCS
+#      directly.  When called from CUDA_ADD_LIBRARY or CUDA_ADD_EXECUTABLE the
+#      nvcc_flags passed in are the same as the flags passed in via the OPTIONS
+#      argument.  The only nvcc flag added automatically is the bitness flag as
+#      specified by CUDA_64_BIT_DEVICE_CODE.  Note that this is a function
+#      instead of a macro.
+#
+#   CUDA_SELECT_NVCC_ARCH_FLAGS(out_variable [target_CUDA_architectures])
+#   -- Selects GPU arch flags for nvcc based on target_CUDA_architectures
+#      target_CUDA_architectures : Auto | Common | All | LIST(ARCH_AND_PTX ...)
+#       - "Auto" detects local machine GPU compute arch at runtime.
+#       - "Common" and "All" cover common and entire subsets of architectures
+#      ARCH_AND_PTX : NAME | NUM.NUM | NUM.NUM(NUM.NUM) | NUM.NUM+PTX
+#      NAME: Kepler Maxwell Kepler+Tesla Maxwell+Tegra Pascal Volta Turing
+#      NUM: Any number. Only those pairs are currently accepted by NVCC though:
+#            3.5 3.7 5.0 5.2 5.3 6.0 6.1 6.2 7.0 7.2 7.5
+#      Returns LIST of flags to be added to CUDA_NVCC_FLAGS in ${out_variable}
+#      Additionally, sets ${out_variable}_readable to the resulting numeric list
+#      Example:
+#       CUDA_SELECT_NVCC_ARCH_FLAGS(ARCH_FLAGS 3.0 3.5+PTX 5.2(5.0) Maxwell)
+#        LIST(APPEND CUDA_NVCC_FLAGS ${ARCH_FLAGS})
+#
+#      More info on CUDA architectures: https://en.wikipedia.org/wiki/CUDA
+#      Note that this is a function instead of a macro.
+#
+#   CUDA_WRAP_SRCS ( cuda_target format generated_files file0 file1 ...
+#                    [STATIC | SHARED | MODULE] [OPTIONS ...] )
+#   -- This is where all the magic happens.  CUDA_ADD_EXECUTABLE,
+#      CUDA_ADD_LIBRARY, CUDA_COMPILE, and CUDA_COMPILE_PTX all call this
+#      function under the hood.
+#
+#      Given the list of files (file0 file1 ... fileN) this macro generates
+#      custom commands that generate either PTX or linkable objects (use "PTX" or
+#      "OBJ" for the format argument to switch).  Files that don't end with .cu
+#      or have the HEADER_FILE_ONLY property are ignored.
+#
+#      The arguments passed in after OPTIONS are extra command line options to
+#      give to nvcc.  You can also specify per configuration options by
+#      specifying the name of the configuration followed by the options.  General
+#      options must precede configuration specific options.  Not all
+#      configurations need to be specified, only the ones provided will be used.
+#
+#         OPTIONS -DFLAG=2 "-DFLAG_OTHER=space in flag"
+#         DEBUG -g
+#         RELEASE --use_fast_math
+#         RELWITHDEBINFO --use_fast_math;-g
+#         MINSIZEREL --use_fast_math
+#
+#      For certain configurations (namely VS generating object files with
+#      CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE set to ON), no generated file will
+#      be produced for the given cuda file.  This is because when you add the
+#      cuda file to Visual Studio it knows that this file produces an object file
+#      and will link in the resulting object file automatically.
+#
+#      This script will also generate a separate cmake script that is used at
+#      build time to invoke nvcc.  This is for several reasons.
+#
+#        1. nvcc can return negative numbers as return values which confuses
+#        Visual Studio into thinking that the command succeeded.  The script now
+#        checks the error codes and produces errors when there was a problem.
+#
+#        2. nvcc has been known to not delete incomplete results when it
+#        encounters problems.  This confuses build systems into thinking the
+#        target was generated when in fact an unusable file exists.  The script
+#        now deletes the output files if there was an error.
+#
+#        3. By putting all the options that affect the build into a file and then
+#        make the build rule dependent on the file, the output files will be
+#        regenerated when the options change.
+#
+#      This script also looks at optional arguments STATIC, SHARED, or MODULE to
+#      determine when to target the object compilation for a shared library.
+#      BUILD_SHARED_LIBS is ignored in CUDA_WRAP_SRCS, but it is respected in
+#      CUDA_ADD_LIBRARY.  On some systems special flags are added for building
+#      objects intended for shared libraries.  A preprocessor macro,
+#      <target_name>_EXPORTS is defined when a shared library compilation is
+#      detected.
+#
+#      Flags passed into add_definitions with -D or /D are passed along to nvcc.
+#
+#
+#
+# The script defines the following variables::
+#
+#   CUDA_VERSION_MAJOR    -- The major version of cuda as reported by nvcc.
+#   CUDA_VERSION_MINOR    -- The minor version.
+#   CUDA_VERSION
+#   CUDA_VERSION_STRING   -- CUDA_VERSION_MAJOR.CUDA_VERSION_MINOR
+#   CUDA_HAS_FP16         -- Whether a short float (float16,fp16) is supported.
+#
+#   CUDA_TOOLKIT_ROOT_DIR -- Path to the CUDA Toolkit (defined if not set).
+#   CUDA_SDK_ROOT_DIR     -- Path to the CUDA SDK.  Use this to find files in the
+#                            SDK.  This script will not directly support finding
+#                            specific libraries or headers, as that isn't
+#                            supported by NVIDIA.  If you want to change
+#                            libraries when the path changes see the
+#                            FindCUDA.cmake script for an example of how to clear
+#                            these variables.  There are also examples of how to
+#                            use the CUDA_SDK_ROOT_DIR to locate headers or

+# FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")

+# This macro is intended to be used in FindXXX.cmake modules files.  It

+# for telling the user where a package was found.  The first argument
+# specifies the name (XXX) of the package.  The second argument
+# specifies the message to display.  The third argument lists details
+# about the find result so that if they change the message will be
+# displayed again.  The macro also obeys the QUIET argument to the
+# find_package command.
+#
+# Example:
+#
+# ::
+#
+#   if(X11_FOUND)
+#     FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"

+# that we keep all symbols, even if they are (seemingly) not used.

+# What caffe2_interface_library does is create an interface library

+    based that does not use data equality and makes the usage of
+    tensors as keys less useful. For instance, the result of
+    ``len({a.crow_indices(), a.crow_indices()})`` is `2`, although,
+    the tensor results from `crow_indices` method call are equal, in
+    fact, these share the same data storage.
+    On the other hand, for efficient caching of tensors we want to
+    avoid calling torch.equal that compares tensors item-wise.
+
+    TensorAsKey offers a compromise in that it guarantees key equality
+    of tensors that references data in the same storage in the same
+    manner and without accessing underlying data. However, this
+    approach does not always guarantee correctness. For instance, for
+    a complex tensor ``x``, we have ``TensorAsKey(x) ==
+    TensorAsKey(x.conj())`` while ``torch.equal(x, x.conj())`` would
+    return False.

+"""Provides optimal triton kernel parameters.
+
+Aim
+---
+
+The usage of optimal triton kernel parameters may increase the
+performance of operations several times. For example, for large tensor
+shapes, the usage of a bsr tensor as mat1 argument in addmm-based
+operations typically outperforms the corresponding operation with
+strided-only inputs when the blocked representation of a tensor
+provides a better alignment with memory access than what the strided
+representation would provide.
+
+Pre-computed kernel parameters
+------------------------------
+
+This script finds and stores the optimal triton kernel parameters for
+a specific set of shape configurations. For instance, the set of shape
+configurations of the bsr_dense_addmm kernel is defined as
+
+  input, out: M x N strided tensor
+  mat1: M x K bsr tensor with blocksize (BM, BK) and given sparsity
+  mat2: M x N strided tensor
+  dtype = float16, bfloat16, float32
+  sparsity = 0.5
+  M = 256, 512, ..., 16384
+  K = M
+  N = 256, 512, ..., 131072
+  BM = 16, 32, ..., 128
+  BK = BM
+  alpha = 1
+  beta = 0, 1
+  GPUs: NVIDIA A100-SXM4-80GB
+
+Approximations
+--------------
+
+It is practically infeasible to pre-compute optimal kernel parameter
+for all possible shape configurations as well as for all existing
+GPUs. Therefore, we'll assume that the pre-computed optimal parameters
+are good enough approximations when
+1) the used GPU is any of NVIDIA A100 Tensor Core GPUs,
+2) the actual sparsity of mat1 is different from sparsity value 0.5.
+
+If a particular shape configuration does not fall in the set of
+pre-computed kernel parameters, or it does not match with the listed
+approximations above, or the used GPU device is not a NVIDIA A100 GPU,
+then a reference set of triton kernel parameters will be used when
+executing operations. The reference kernel parameters are defined in
+torch/sparse/_triton_ops.py, see bsr_dense_addmm_meta function, for
+instance.
+
+Computing optimal kernel parameters
+-----------------------------------
+
+If the approximations listed above are unacceptable, e.g. when one
+seeks a maximal performance possible, the optimal kernel parameters
+for a particular GPU can be computed by simply running this script in
+the pytorch development tree::
+
+  cd /path/to/pytorch
+  python -m pip install --no-build-isolation -v -e .
+  python torch/sparse/_triton_ops_meta.py
+
+This will compute the optimal kernel parameters for the GPU device
+available in the host system for all shape configurations listed in
+"Pre-computed kernel parameters" above. The results will be stored in
+the database of kernel parameters. Currently, this database is defined
+as this module (see "BEGIN GENERATED DATA" comment below) that will be
+modified when the script is run. Create a pytorch PR with the
+corresponding modifications in this file to make the computed optimal
+kernel parameters available for other users as pre-computed kernel
+parameters.
+
+Moreover, one can compute the optimal kernel parameters for a specific
+set of shape configurations and specific sparsity patterns. For that,
+use tuning functions provided by this module:
+
+  tune_bsr_dense_addmm(input, mat1, mat2, beta=1, alpha=1, out=None, verbose=False, store=False) -> meta
+
+The tuning functions return a dictionary of optimal kernel parameters
+that can be passed to the corresponding operation, e.g.
+
+  bsr_dense_addmm(..., meta=meta)
+
+Or, when store==True, the optimal kernel parameters will be stored in
+the database of pre-computed kernel parameters in runtime so that all
+addmm-based operations such as torch.addmm, torch.mm,
+torch.nn.functional.linear will benefit from using the computed
+optimal set of kernel parameters.
+
+Note that running tune_bsr_dense_addmm can take several minutes. So,
+use it wisely, e.g. by implementing persistent storage of optimized
+kernel parameters. See the source code of get_meta and
+tune_bsr_dense_addmm to learn how to register a custom set of optimal
+kernel parameters for addmm-based operations.

+class SparseSemiStructuredTensor(torch.Tensor):
+    """
+    This class implements semi-structured sparsity as a Tensor subclass.
+
+    Semi-structured sparsity describes a sparsity pattern where n in every 2n elements are sparse,
+    depending on the datatype. It is also referred to as 2:4 sparsity or fine-grained
+    structured sparsity.
+
+    There are two backends available for semi_structred sparsity, either cuSPARSELt or CUTLASS.
+    This class is meant to serve as a base class for both implementations. SparseSemiStructuredCUTLASS
+    and SparseSemiStructuredCUSPARSELT both inherit from this class and define three backend-specific items.

+        Then it creates the packed and meta tensors for the compressed sparse representation of the pruned dense tensor.
+        It also calculates the packed_t and meta_t tensors for the compressed sparse representation of the transposed
+        pruned dense tensor.
+        Since we cannot transpose the compressed representations, we store both for the fw/bw pass respectively.
+
+        Finally, this function also computes a compressed swizzled bitmask that encodes the sparsity pattern
+        This can be used in the backward pass to mask the gradients.

+        :func:`~torch.testing.assert_close` is highly configurable with strict default settings. Users are encouraged
+        to :func:`~functools.partial` it to fit their use case. For example, if an equality check is needed, one might
+        define an ``assert_equal`` that uses zero tolerances for every ``dtype`` by default:

+
+    Args:
+        shape (Tuple[int, ...]): Single integer or a sequence of integers defining the shape of the output tensor.
+        dtype (:class:`torch.dtype`): The data type of the returned tensor.
+        device (Union[str, torch.device]): The device of the returned tensor.
+        low (Optional[Number]): Sets the lower limit (inclusive) of the given range. If a number is provided it is
+            clamped to the least representable finite value of the given dtype. When ``None`` (default),
+            this value is determined based on the :attr:`dtype` (see the table above). Default: ``None``.
+        high (Optional[Number]): Sets the upper limit (exclusive) of the given range. If a number is provided it is
+            clamped to the greatest representable finite value of the given dtype. When ``None`` (default) this value

+                Passing ``low==high`` to :func:`~torch.testing.make_tensor` for floating or complex types is deprecated
+                since 2.1 and will be removed in 2.3. Use :func:`torch.full` instead.
+
+        requires_grad (Optional[bool]): If autograd should record operations on the returned tensor. Default: ``False``.
+        noncontiguous (Optional[bool]): If `True`, the returned tensor will be noncontiguous. This argument is
+            ignored if the constructed tensor has fewer than two elements. Mutually exclusive with ``memory_format``.
+        exclude_zero (Optional[bool]): If ``True`` then zeros are replaced with the dtype's small positive value
+            depending on the :attr:`dtype`. For bool and integer types zero is replaced with one. For floating
+            point types it is replaced with the dtype's smallest positive normal number (the "tiny" value of the
+            :attr:`dtype`'s :func:`~torch.finfo` object), and for complex types it is replaced with a complex number
+            whose real and imaginary parts are both the smallest positive normal number representable by the complex
+            type. Default ``False``.
+        memory_format (Optional[torch.memory_format]): The memory format of the returned tensor. Mutually exclusive
+            with ``noncontiguous``.
+
+    Raises:
+        ValueError: If ``requires_grad=True`` is passed for integral `dtype`

+# Note [Writing Test Templates]
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#
+# This note was written shortly after the PyTorch 1.9 release.
+# If you notice it's out-of-date or think it could be improved then please
+# file an issue.
+#
+# PyTorch has its own framework for instantiating test templates. That is, for
+#   taking test classes that look similar to unittest or pytest
+#   compatible test classes and optionally doing the following:
+#
+#     - instantiating a version of the test class for each available device type
+#         (often the CPU, CUDA, and META device types)
+#     - further instantiating a version of each test that's always specialized
+#         on the test class's device type, and optionally specialized further
+#         on datatypes or operators
+#
+# This functionality is similar to pytest's parametrize functionality
+#   (see https://docs.pytest.org/en/6.2.x/parametrize.html), but with considerable
+#   additional logic that specializes the instantiated test classes for their
+#   device types (see CPUTestBase and CUDATestBase below), supports a variety
+#   of composable decorators that allow for test filtering and setting
+#   tolerances, and allows tests parametrized by operators to instantiate
+#   only the subset of device type x dtype that operator supports.
+#
+# This framework was built to make it easier to write tests that run on
+#   multiple device types, multiple datatypes (dtypes), and for multiple
+#   operators. It's also useful for controlling which tests are run. For example,
+#   only tests that use a CUDA device can be run on platforms with CUDA.
+#   Let's dive in with an example to get an idea for how it works:
+#
+# --------------------------------------------------------
+# A template class (looks like a regular unittest TestCase)
+# class TestClassFoo(TestCase):
+#
+#   # A template test that can be specialized with a device
+#   # NOTE: this test case is not runnable by unittest or pytest because it
+#   #   accepts an extra positional argument, "device", that they do not understand
+#   def test_bar(self, device):
+#     pass
+#
+# # Function that instantiates a template class and its tests
+# instantiate_device_type_tests(TestCommon, globals())
+# --------------------------------------------------------
+#
+# In the above code example we see a template class and a single test template
+#   that can be instantiated with a device. The function
+#   instantiate_device_type_tests(), called at file scope, instantiates
+#   new test classes, one per available device type, and new tests in those
+#   classes from these templates. It actually does this by removing
+#   the class TestClassFoo and replacing it with classes like TestClassFooCPU
+#   and TestClassFooCUDA, instantiated test classes that inherit from CPUTestBase
+#   and CUDATestBase respectively. Additional device types, like XLA,
+#   (see https://github.com/pytorch/xla) can further extend the set of
+#   instantiated test classes to create classes like TestClassFooXLA.
+#
+# The test template, test_bar(), is also instantiated. In this case the template
+#   is only specialized on a device, so (depending on the available device
+#   types) it might become test_bar_cpu() in TestClassFooCPU and test_bar_cuda()
+#   in TestClassFooCUDA. We can think of the instantiated test classes as
+#   looking like this:
+#
+# --------------------------------------------------------
+# # An instantiated test class for the CPU device type
+# class TestClassFooCPU(CPUTestBase):
+#
+#   # An instantiated test that calls the template with the string representation
+#   #   of a device from the test class's device type
+#   def test_bar_cpu(self):
+#     test_bar(self, 'cpu')
+#
+# # An instantiated test class for the CUDA device type
+# class TestClassFooCUDA(CUDATestBase):

+#   # An instantiated test that calls the template with the string representation
+#   #   of a device from the test class's device type
+#   def test_bar_cuda(self):
+#     test_bar(self, 'cuda:0')
+# --------------------------------------------------------
+#
+# These instantiated test classes ARE discoverable and runnable by both
+#   unittest and pytest. One thing that may be confusing, however, is that
+#   attempting to run "test_bar" will not work, despite it appearing in the
+#   original template code. This is because "test_bar" is no longer discoverable
+#   after instantiate_device_type_tests() runs, as the above snippet shows.
+#   Instead "test_bar_cpu" and "test_bar_cuda" may be run directly, or both
+#   can be run with the option "-k test_bar".
+#
+# Removing the template class and adding the instantiated classes requires
+#   passing "globals()" to instantiate_device_type_tests(), because it
+#   edits the file's Python objects.
+#
+# As mentioned, tests can be additionally parametrized on dtypes or
+#   operators. Datatype parametrization uses the @dtypes decorator and
+#   require a test template like this:
+#
+# --------------------------------------------------------
+# # A template test that can be specialized with a device and a datatype (dtype)
+# @dtypes(torch.float32, torch.int64)
+# def test_car(self, device, dtype)
+#   pass
+# --------------------------------------------------------
+#
+# If the CPU and CUDA device types are available this test would be
+#   instantiated as 4 tests that cover the cross-product of the two dtypes
+#   and two device types:
+#
+#     - test_car_cpu_float32
+#     - test_car_cpu_int64
+#     - test_car_cuda_float32
+#     - test_car_cuda_int64
+#
+# The dtype is passed as a torch.dtype object.
+#
+# Tests parametrized on operators (actually on OpInfos, more on that in a
+#   moment...) use the @ops decorator and require a test template like this:
+# --------------------------------------------------------
+# # A template test that can be specialized with a device, dtype, and OpInfo
+# @ops(op_db)
+# def test_car(self, device, dtype, op)
+#   pass
+# --------------------------------------------------------
+#
+# See the documentation for the @ops decorator below for additional details
+#   on how to use it and see the note [OpInfos] in
+#   common_methods_invocations.py for more details on OpInfos.
+#
+# A test parametrized over the entire "op_db", which contains hundreds of
+#   OpInfos, will likely have hundreds or thousands of instantiations. The
+#   test will be instantiated on the cross-product of device types, operators,
+#   and the dtypes the operator supports on that device type. The instantiated
+#   tests will have names like:
+#
+#     - test_car_add_cpu_float32
+#     - test_car_sub_cuda_int64
+#
+# The first instantiated test calls the original test_car() with the OpInfo
+#   for torch.add as its "op" argument, the string 'cpu' for its "device" argument,
+#   and the dtype torch.float32 for is "dtype" argument. The second instantiated
+#   test calls the test_car() with the OpInfo for torch.sub, a CUDA device string
+#   like 'cuda:0' or 'cuda:1' for its "device" argument, and the dtype
+#   torch.int64 for its "dtype argument."
+#
+# In addition to parametrizing over device, dtype, and ops via OpInfos, the
+#   @parametrize decorator is supported for arbitrary parametrizations:
+# --------------------------------------------------------
+# # A template test that can be specialized with a device, dtype, and value for x
+# @parametrize("x", range(5))
+# def test_car(self, device, dtype, x)
+#   pass
+# --------------------------------------------------------
+#
+# See the documentation for @parametrize in common_utils.py for additional details
+#   on this. Note that the instantiate_device_type_tests() function will handle
+#   such parametrizations; there is no need to additionally call
+#   instantiate_parametrized_tests().
+#
+# Clever test filtering can be very useful when working with parametrized
+#   tests. "-k test_car" would run every instantiated variant of the test_car()
+#   test template, and "-k test_car_add" runs every variant instantiated with
+#   torch.add.
+#
+# It is important to use the passed device and dtype as appropriate. Use
+#   helper functions like make_tensor() that require explicitly specifying
+#   the device and dtype so they're not forgotten.
+#
+# Test templates can use a variety of composable decorators to specify
+#   additional options and requirements, some are listed here:
+#
+#     - @deviceCountAtLeast(<minimum number of devices to run test with>)
+#         Passes a list of strings representing all available devices of
+#         the test class's device type as the test template's "device" argument.
+#         If there are fewer devices than the value passed to the decorator
+#         the test is skipped.
+#     - @dtypes(<list of tuples of dtypes>)
+#         In addition to accepting multiple dtypes, the @dtypes decorator
+#         can accept a sequence of tuple pairs of dtypes. The test template
+#         will be called with each tuple for its "dtype" argument.
+#     - @onlyNativeDeviceTypes
+#         Skips the test if the device is not a native device type (currently CPU, CUDA, Meta)
+#     - @onlyCPU
+#         Skips the test if the device is not a CPU device
+#     - @onlyCUDA
+#         Skips the test if the device is not a CUDA device
+#     - @onlyMPS
+#         Skips the test if the device is not a MPS device
+#     - @skipCPUIfNoLapack
+#         Skips the test if the device is a CPU device and LAPACK is not installed
+#     - @skipCPUIfNoMkl
+#         Skips the test if the device is a CPU device and MKL is not installed
+#     - @skipCUDAIfNoMagma
+#         Skips the test if the device is a CUDA device and MAGMA is not installed
+#     - @skipCUDAIfRocm
+#         Skips the test if the device is a CUDA device and ROCm is being used
+
+
+# Note [Adding a Device Type]
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#
+# To add a device type:
+#
+#   (1) Create a new "TestBase" extending DeviceTypeTestBase.
+#       See CPUTestBase and CUDATestBase below.
+#   (2) Define the "device_type" attribute of the base to be the
+#       appropriate string.
+#   (3) Add logic to this file that appends your base class to
+#       device_type_test_bases when your device type is available.
+#   (4) (Optional) Write setUpClass/tearDownClass class methods that
+#       instantiate dependencies (see MAGMA in CUDATestBase).
+#   (5) (Optional) Override the "instantiate_test" method for total
+#       control over how your class creates tests.
+#
+# setUpClass is called AFTER tests have been created and BEFORE and ONLY IF
+# they are run. This makes it useful for initializing devices and dependencies.

+#    - DO NOT import common_device_type inside the file.
+#      `runpy.run_path` with `globals()` already properly setup the context so that
+#      `DeviceTypeTestBase` is already available.
+#    - Set a top-level variable `TEST_CLASS` equal to your new class.
+#      E.g. TEST_CLASS = XLATensorBase
+#  - To run tests with new device type, set `TORCH_TEST_DEVICE` env variable to path

+# NOTE [How to check NN module / functional API parity between Python and C++ frontends]
+#
+# The way to check API parity is to add parity tests for the NN module / functional of interest.
+# Here are the detailed steps:
+#
+# For NN module:
+# 1. Make sure you already have a test dict with the module configuration you want to test.
+# 2. Add `cpp_constructor_args` entry to the test dict, with its value exactly matching
+#    the Python module constructor arguments. For example, if in the test dict we pass
+#    `(10, 8)` to `torch.nn.Linear` constructor, then we should pass `torch::nn::LinearOptions(10, 8)`
+#    as the corresponding C++ constructor argument to `torch::nn::Linear`.
+# 3. If in the process of performing the above step you referenced any variables
+#    in the `cpp_constructor_args` entry, you must add `cpp_var_map` entry
+#    to the test dict to make sure that those variables are populated with the right Python values.
+#    For example, if the Python constructor call is
+#    `torch.nn.FractionalMaxPool2d(2, output_ratio=0.5, _random_samples=random_samples)`,
+#    the corresponding C++ constructor argument is
+#    `torch::nn::FractionalMaxPool2dOptions(2).output_ratio(0.5)._random_samples(random_samples)`,
+#    and the `cpp_var_map` entry must be
+#    `{'random_samples': random_samples}` in order to populate the C++ variable `random_samples`
+#    used in the C++ constructor argument with the Python tensor value `random_samples`.
+#
+# For NN functional:
+# 1. Make sure you already have a test dict with the functional configuration you want to test.
+# 2. If the test dict's `constructor` entry looks like `wrap_functional(F.some_functional_name, ...)`,
+#    then you must add `cpp_options_args` entry to the test dict, with its value exactly matching the Python
+#    functional optional arguments. For example, if the test dict's `constructor` entry is
+#    `wrap_functional(F.interpolate, size=12, scale_factor=None, mode='nearest')`,
+#    then the `cpp_options_args` entry should be
+#    "F::InterpolateFuncOptions().size(std::vector<int64_t>({12})).scale_factor(std::nullopt).mode(torch::kNearest)".
+# 3. Otherwise, if the test dict's `constructor` entry looks like
+#    `wrap_functional(lambda i: F.some_functional_name(...))`,
+#    then you must add `cpp_function_call` entry to the test dict, with its value exactly matching the Python
+#    functional function call. For example, if the test dict's `constructor` entry is
+#    `wrap_functional(lambda i: F.poisson_nll_loss(i, t.type_as(i), reduction='none'))`,
+#    then the `cpp_function_call` entry should be
+#    "F::poisson_nll_loss(i, t.to(i.options()), F::PoissonNLLLossFuncOptions().reduction(torch::kNone))".
+# 4. If in the process of performing the above two steps you referenced any variables
+#    in the `cpp_options_args` or `cpp_function_call` entry, you must
+#    add `cpp_var_map` entry to the test dict to make sure that those variables
+#    are populated with the right Python values. For example, if the test dict's `constructor` entry is
+#    `wrap_functional(lambda i: F.poisson_nll_loss(i, t.type_as(i), reduction='none'))`,
+#    then the `cpp_function_call` entry should be
+#    "F::poisson_nll_loss(i, t.to(i.options()), F::PoissonNLLLossFuncOptions().reduction(torch::kNone))".
+#    Notice that there are two variables `i` and `t` that need to have their values provided,
+#    and the way to do so is to add a `cpp_var_map` entry: `cpp_var_map={'i': '_get_input()', 't': t}`.
+#    (Note that for `i`, since we want it to take the Python input value, we pass '_get_input()' string as value
+#    and the C++ parity test mechanism will populate `i` with the Python input value correctly.)
+#
+# There are also a few optional flags in the test dict to control the C++ parity test behavior:
+#
+# - `test_cpp_api_parity`: if `False`, skips the C++ parity test for this test dict. Default: True.
+# - `has_parity`: if `False`, expects this test dict to fail the C++ parity test. Default: True.

+# NOTE: [optimizer kwarg categories]
+# We categorize optimizer kwargs as 3 types:
+#  1. optimizer-specific flags are like amsgrad or rho or beta, flags that are specific to
+#     algorithms and thus only show up for certain optimizers. There are many of these, so I
+#     do not bother gathering them all and listing them here. The converse to these would be
+#     global flags that every optimizer ideally _should_ support. We break global flags into
+#     2 further categories and list them all below.
+#  2. global-friendly = ["lr", "weight_decay", "maximize", "capturable"]
+#     global-friendly flags are global flags who play nicely with all other global flags,
+#     i.e., are mutually exclusive in function. This means that any pair of the following
+#     flags can be toggled at once (e.g., maximize and weight_decay). Furthermore, any of the
+#     following flags theoretically can be enabled with ANY other global flag, including the
+#     cliquey ones (e.g, capturable and foreach).
+#  3. global-cliquey = ["foreach", "fused", "differentiable"]
+#     global-cliquey flags are global flags that do NOT coexist with other cliquey flags,
+#     usually because they contradict each other in function. For example, one should not flip
+#     both foreach AND fused to True, because they are two differing performance optimizations
+#     in which you can only opt into one.
+#
+# The following optim_inputs_func_* sampling functions only return constructor combinations of
+# optimizer-specific and global-friendly flags. This is because we are confident they would mesh
+# well with additional kwargs. On the flip side of the same coin, we reserve setting the
+# global-cliquey flags to individual tests and fully expect tests to edit OptimizerInput.kwargs.

+class parametrize(_TestParametrizer):
+    """
+    Decorator for applying generic test parametrizations.
+
+    The interface for this decorator is modeled after `@pytest.mark.parametrize`.
+    Basic usage between this decorator and pytest's is identical. The first argument
+    should be a string containing comma-separated names of parameters for the test, and
+    the second argument should be an iterable returning values or tuples of values for
+    the case of multiple parameters.
+
+    Beyond this basic usage, the decorator provides some additional functionality that
+    pytest does not.
+
+    1. Parametrized tests end up as generated test functions on unittest test classes.
+    Since this differs from how pytest works, this decorator takes on the additional
+    responsibility of naming these test functions. The default test names consists of
+    the test's base name followed by each parameter name + value (e.g. "test_bar_x_1_y_foo"),
+    but custom names can be defined using `name_fn` or the `subtest` structure (see below).
+
+    2. The decorator specially handles parameter values of type `subtest`, which allows for
+    more fine-grained control over both test naming and test execution. In particular, it can
+    be used to tag subtests with explicit test names or apply arbitrary decorators (see examples
+    below).
+
+    Examples::
+
+        @parametrize("x", range(5))
+        def test_foo(self, x):
+            ...
+
+        @parametrize("x,y", [(1, 'foo'), (2, 'bar'), (3, 'baz')])
+        def test_bar(self, x, y):
+            ...
+
+        @parametrize("x,y", [(1, 'foo'), (2, 'bar'), (3, 'baz')],
+                     name_fn=lambda x, y: '{}_{}'.format(x, y))
+        def test_bar_custom_names(self, x, y):
+            ...
+
+        @parametrize("x, y", [subtest((1, 2), name='double'),
+                              subtest((1, 3), name='triple', decorators=[unittest.expectedFailure]),
+                              subtest((1, 4), name='quadruple')])
+        def test_baz(self, x, y):
+            ...
+
+    To actually instantiate the parametrized tests, one of instantiate_parametrized_tests() or
+    instantiate_device_type_tests() should be called. The former is intended for test classes
+    that contain device-agnostic tests, while the latter should be used for test classes that
+    contain device-specific tests. Both support arbitrary parametrizations using the decorator.

+
+        Sampling method
+        ---------------
+
+        The used sampling method was introduced in
+        https://pearu.github.io/csr_sampling.html, and here we give
+        only an overall description of the method.
+
+        Notice that crow_indices can be defined as cumsum(counts)
+        where counts is a sequence of non-negative integers satisfying
+        the following conditions:
+
+          len(counts) == n_rows + 1
+          counts.max() <= n_cols
+
+        while counts[i + 1] is interpreted as the number of specified
+        elements in the i-th row.
+
+        The used sampling method aims at increasing the diversity of
+        CSR samples, that is, a CSR sample should contain (i) rows
+        that are all filled, (ii) rows with no elements at all, and
+        (iii) rows that are partially filled. At the same time and for
+        the given total number of specified elements (nnz), there
+        should be minimal preference to rows with a given number of
+        elements.  To achieve this, the sampling method is built-up on
+        using a sawteeth model for counts. In the simplest case, we
+        would have
+
+          counts = arange(n_rows + 1) % (n_cols + 1)
+
+        that has equal number of all possible column counts per row.
+        This formula can be used only for specific input values of
+        n_rows, n_cols, and nnz. To generalize this model to any
+        combinations of inputs, the counts model above is extended
+        with an incomplete sawtooth, and the right and lower
+        rectangular parts that will guarantee that
+
+          counts.sum() == nnz
+
+        for any combination of n_rows, n_cols, and nnz. Basically,
+        we'll find a maximal window in (n_rows + 1, n_cols + 1)-grid
+        that is able to hold a sequence of sawteeth and so-called
+        final correction, while the external part of the window is
+        filled with counts to meet the nnz constraint exactly.

+# groups.  However, our regular PG implementations perform a dispatch through
+# c10d, whereas Threaded PG does not for some reason (some superficial
+# but not very convincing reasons include that Threaded PG is implemented
+# in Python but you can't override Backend in Python, you can only override
+# ProcessGroup in Python), thereby bypassing the dispatch step.  Now we have
+# a problem: c10d's signatures are LIES, they mutate their (output) tensor
+# arguments but their annotations don't have mutations on them so we don't
+# actually update any view metadata if you do differentiation.  This
+# ordinarily "doesn't matter" because distributed collectives aren't
+# differentiable anyway, but it's possible to tickle this in testing if
+# someone tries to touch the grad_fn of a Tensor.  There a few ways to
+# fix this, but the easiest way was to use the .detach() trick to hide
+# the mutations from autograd.

+# file an issue.
+#
+# See also: the OpInfo tracker (https://github.com/pytorch/pytorch/issues/54261)

+#
+# An OpInfo is a collection of metadata related to a PyTorch operator. This
+#   metadata is used to generate tests that validate properties of the operator,
+#   like if it implements the correct gradient formula.
+#
+# WHY OPINFOS?
+# ~~~~~~~~~~~~
+#
+# OpInfos are principally intended to do three things:
+#
+#   1) to allow systematic testing over all PyTorch's operators
+#   2) to simplify operating testing by autogenerating many tests
+#   3) to allow systems (like autograd, torchscript, fx, nnc...) to test
+#        against every PyTorch operator
+#
+# All these goals are still a work in progress. Not every operator has an
+#   OpInfo, and some operator tests that could be automatically generated
+#   still have to be written manually.
+#
+# It's helpful to understand that OpInfos are both about test simplification and
+#   modularity. PyTorch is a complicated framework with many interrelated systems,
+#   too many for any one person to keep track of. An OpInfo can be thought of as the
+#   interface between an operator implementer and those other systems. Instead of
+#   requiring the implementer of torch.foo understand how to test its forward
+#   mode AD or NNC support that's typically handled automatically just by
+#   defining an OpInfo.
+#
+# It's often surprising to OpInfo writers that just implementing an OpInfo
+#   typically can't verify an operator is actually implemented correctly:
+#
+# "If an OpInfo doesn't validate my op works as expected, what's the point
+#     of it?"
+#
+# But the point of is the above. OpInfos are intended to let you focus on testing
+#   the operator logic you're familiar with instead of having to write tests for
+#   how the operator interacts with each of PyTorch's many systems.
+#
+# And, OK, it turns out that SOMETIMES just writing an OpInfo DOES
+#   validate your op works as expected, but that's only in special
+#   cases. See below for details.
+#
+# WHAT'S AN OPINFO?
+# ~~~~~~~~~~~~~~~~~
+#
+# So what is an OpInfo? It's a Python class that describes an operator's properties,
+#   like which dtypes it supports on the CPU and whether it has any aliases.
+#   These properties can be divided into three categories:
+#
+#   1) Metadata describing the operator, like the operator's name and if it
+#     "supports" the out kwarg.
+#   2) Test directives, like "skips" that tell the test suite to skip some
+#     tests.
+#   3) A "sample inputs" function that generates valid inputs for the operator.
+#
+# OpInfo attributes are described in more detail below.
+#
+# THE SAMPLE INPUTS FUNCTION
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~
+#
+# The "sample inputs" function merits special elaboration. This function is
+#   crucial to testing with OpInfos. A typical OpInfo test has to treat the operator
+#   as a black box. There's no structure for the test to understand or exploit.
+#   Without "sample inputs" it wouldn't even know how to call the OpInfo's
+#   operator. The sample input function saves the day by providing different
+#   "SampleInputs" that can be used to call the operator. A sample input
+#   function should have the following signature:
+#
+#   def sample_inputs_foo(op_info, device, dtype, requires_grad, **kwargs):
+#
+#   And should return an iterable of SampleInputs (see the class description
+#   above). Each SampleInput defines an "input", "args", "kwargs", an
+#   "output_process_fn_grad" function, the "broadcasts_input" bool and a
+#   "name".
+#
+#   All the "sample_inputs" functions are invoked within a `torch.no_grad()`
+#   environment for efficiency and correctness. As such remember to set the
+#   "requires_grad" flag on the inputs **after** performing any transformations
+#   on them.
+#
+# The "input" is the first argument to the operator, or the tensor that
+#   the method or inplace variants of the operator should be called on, and
+#   should be on the requested device, of the requested dtype, and its
+#   requires_grad attribute should be set to the requires_grad argument.
+#
+# "args" should contain positional arguments, and "kwargs" keyword arguments.
+#
+# "output_process_fn_grad" has an interesting name. It's a function that maps
+#   the operator's output (when given the input, args, and kwargs) to the
+#   portion of the output to gradcheck. For example, consider an operator
+#   like torch.linalg.slogdet
+#   (https://pytorch.org/docs/main/generated/torch.linalg.slogdet.html).
+#   This operator returns a tuple of two tensors, but the first tensor
+#   cannot be backwarded through. Its "output_process_fn_grad" filters
+#   this output tuple to just the second argument, which we can call backward
+#   on. Functions that produce a single tensor can ignore this argument.
+#
+# "broadcasts_input" is a bool indicated if the SampleInput causes the operator
+#   to broadcast the "input" argument. This is important for tests to understand
+#   because inplace variants of operations throw a runtime error if they
+#   would broadcast their input arguments, so tests that work with inplace
+#   variants filter SampleInputs that broadcast their input.
+#
+# "name" is a string that's just used for debugging. It appears when printing
+#   the SampleInput.
+#
+# Sample inputs are designed to be used with many tests, some
+#   that are very time consuming, so they should be a small
+#   set with small tensors. An elaborated set of sample inputs
+#   can be specified using the "reference_inputs_func" attribute.
+#   The "reference inputs" for an operation are an extended
+#   set of sample inputs that can more exhaustively test an
+#   operator. They are used by only a few tests that are careful
+#   not to take too long to run. Adding reference inputs
+#   is highly encouraged!
+#
+# THE (OPTIONAL) ERROR INPUTS FUNCTION
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#
+# OpInfos may optionally specify "error inputs" through an error function. If
+#   specified test_errors in test_ops.py will call the op with these inputs
+#   and validate that the desired error is thrown.
+#
+# Error inputs automate a common testing pattern where multiple inputs are
+#   passed to an operation and the errors they thrown are reviewed. Tests
+#   written in this style should be ported to the new OpInfo pattern.
+#
+# Error inputs are specified using the ErrorInputs class, which contains
+#   a SampleInput (see above) and data about the expected error.
+#
+# OPINFO FILE ORGANIZATION
+# ~~~~~~~~~~~~~~~~~~~~~~~~
+#
+# All OpInfos are currently defined in this file. Most OpInfo tests are defined
+#   in test_ops.py, but some system-specific tests are defined in those
+#   systems' test files, and subclass-specific tests are defined in the test
+#   file that corresponds to that subclass (see the below).
+#   Expect a reorganization in the future.
+#
+# WHAT'S TESTED?
+# ~~~~~~~~~~~~~~
+#
+# Every OpInfo in the op_db sequence has the following properties validated in
+# test_ops.py:
+#
+#   - that its supported dtypes are specified correctly
+#   - that the operation produces the same results when called with noncontiguous inputs
+#   - that it supports the out= argument properly (if it allows out=),
+#       see https://github.com/pytorch/pytorch/wiki/Developer-FAQ#how-does-out-work-in-pytorch
+#   - that it works with the conjugate view bit properly
+#   - that its function, method, and inplace variants perform the same operation
+#       (that is, that torch.add, torch.Tensor.add, and torch.Tensor.add_ all
+#       do the same thing).
+#   - that its inplace variant preserves the input's storage
+#   - that its gradient formula is implemented correctly, and that it supports
+#       gradgrad and complex grad and gradgrad and forward mode AD properly for
+#       the op's function and inplace variants (method variants are skipped
+#       to reduce test time).
+#   - that the operation performs the same operation when traced or scripted
+#       using the jit
+#   - that the operation is autodifferentiated by the jit as expected
+#   - that the operator's aliases, if any, perform the same operation and that
+#       the jit understands the alias
+#   - that the operator throws the correct errors (if error_inputs is defined)
+#   - that the operator produces the same results as a NumPy reference (if ref is defined)
+#   - that the operator produces the same results as a NumPy reference on an extended
+#       set of "reference inputs" (if both ref and reference_inputs_func are defined)
+#       (NOTE: elementwise unary and elementwise binary OpInfos do this even if only
+#         ref is defined, because they effectively autogenerate reference inputs)
+#   - that the operator works on different CUDA devices
+#
+# Additional OpInfo tests are in test_jit_fuser_te.py, test_fx_experimental.py,
+#   and test_fx.py. These tests validate that operators work with NNC and FX
+#   as expected.
+#
+# For performance, some of the above tests may only run on the first
+#   SampleInput returned by an OpInfo's sample input function.
+#
+# In addition to these tests, some subclasses (discussed in the next section)
+#   define additional tests.
+#
+# Critically, as mentioned above, what's not necessarily tested is that the operator
+#   works as expected. When implementing an OpInfo an engineer must still
+#   typically write one or more tests validating the operator's behavior.
+#   The exception to this is if reference testing is sufficient, or if
+#   the operation belongs to an OpInfo subclass that has more exhaustive
+#   operator testing. Elementwise unary and elementwise binary operators,
+#   in particular, usually don't require additional testing beyond
+#   writing an Opinfo.
+#
+#
+# OPINFO (SUB)CLASSES
+# ~~~~~~~~~~~~~~~~~~~
+#
+# In addition to the OpInfo base class there are several specialized OpInfo
+#   subclasses. For example, the UnaryUfuncInfo subclass is used for
+#   unary elementwise operations. These operations have a common structure
+#   that test_unary_ufuncs.py exploits with additional automated testing.
+#   The automated testing in test_unary_ufuncs.py is so thorough, comparing
+#   the operator to a NumPy reference function on a plethora of values, that
+#   just implementing an OpInfo for a unary elementwise operation is often
+#   sufficient testing.
+#
+# The ForeachFuncInfo is another OpInfo subclass that is hyper-specialized to a
+#   very unique class of operations. These OpInfos aren't included in the
+#   op_db sequence and have their own tests.
+#
+# Other OpInfo subclasses, like SpectralFuncInfo, are just for convenience
+# when writing OpInfos.
+#
+# TESTING A NEW OPERATOR
+# ~~~~~~~~~~~~~~~~~~~~~~
+#
+# If you're adding a new operator to any of the following namespaces:
+#   - torch
+#   - torch.fft
+#   - torch.linalg,
+#   - torch.special
+#   - torch.nn.functional
+# then you should typically add an OpInfo for it.
+#
+# As mentioned a couple times above, implementing an OpInfo is not
+#   usually sufficient testing (unless the operator is a unary or binary elementwise
+#   operator). The OpInfo will only test the properties described in the
+#   "WHAT'S TESTED" section. It DOES NOT necessarily verify that the operator is
+#   implemented correctly.
+#
+# TIPS FOR WRITING AN OPINFO AND OPINFO TESTS
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#
+# Writing an OpInfo can be a little daunting. Since the point of an OpInfo is to
+#   be consumed by a variety of systems it can be hard to understand how to
+#   deal with test failures or how to set the OpInfo metadata properly.
+#
+# Before adding an OpInfo it helps to look at other OpInfos. A sample inputs
+#   function must be defined, and the operator's dtypes must be specified.
+#   Once that's done you should run the operator's tests in test_ops.py
+#   (these can be filtered using the "-k" argument in pytest). Tests that
+#   fail should provide an error message that describes what to change about
+#   your OpInfo. You don't need to worry about changing an OpInfo's default
+#   values unless a test yells at you.
+#
+# Similarly, if you're writing a test that consumes OpInfos then it's critical
+#   your test provides a clear error message describing what to do when it
+#   fails. You should not assume the OpInfo implementer is familiar with your
+#   system.
+#
+# If you see a confusing error message while developing an OpInfo then please
+#   file an issue describing what happened.
+#
+# This trial-and-error approach to writing an OpInfo can be frustrating,
+#   but it's probably necessary as long as OpInfos don't require
+#   learning about all the systems that consume them. One thing that can help
+#   is the get_supported_dtypes() function defined in utils.py. This
+#   function can be used to programmatically specify the dtypes an operator
+#   supports, and is especially useful if writing an OpInfo on a machine
+#   without a CUDA device. See its documentation for more details.
+#

+# comes to implementation as it determines how a reduction can be parallelized.

+# For example, many summary statistics such as median, mode and quantile cannot
+# be computed from partial results because these are sorting and counting based
+# algorithms that need information that would be lost in the reduced value.

+    - If your operator is non-differentiable, then you should register

+# This module provides a FAST (on GPU) content addressable store for storages
+# (and tensors on top of them) with VERY WEAK portability guarantees (e.g.,
+# don't expect CPU/CUDA to address to the same hash, don't expect it to be
+# portable across devices) that is NOT cryptographically secure.  In return,
+# we are able to hash 40G of tensor data on GPU in less than a second,
+# compared to running SHA-1 in CPU which would a minute or so.  The primary
+# use case is for efficiently snapshotting intermediate tensor data for
+# offline debugging, but it's been put in this module in case you think of
+# another use case for it.  The hash function could be replaced with a
+# straight reimplementation of SHA-1, which would give us much stronger
+# portability guarantees.
+#
+# WARNING: THERE IS NO BC/FC GUARANTEE FOR THIS FORMAT!  If you need to format
+# shift the result, consider packing it into a single torch.save object
+# with traditional view sharing.
+#
+# Because of the weak portability guarantees, you can only write to the
+# content store from a single process; we don't provide any capability
+# of "reopening" a content store to add more things to it.  But we don't
+# assume that you can keep all of the tensors you want to add to the store
+# in memory at once, because you probably can't!  Nor do we assume that
+# you know a priori whether or not two storages can be deduplicated or not.
+#
+# Note: only storages are content-addressed; tensors are name addressed
+#
+# Note: our padding strategy means that [1, 0] and [1] int16 tensors would
+# map to the same (padded) storage.  We think this will be immaterial for most
+# users.

+Contains utility functions for working with nested python data structures.
+
+A *pytree* is Python nested data structure. It is a tree in the sense that
+nodes are Python collections (e.g., list, tuple, dict) and the leaves are
+Python values. Furthermore, a pytree should not contain reference cycles.
+
+pytrees are useful for working with nested collections of Tensors. For example,
+one can use `tree_map` to map a function over all Tensors inside some nested
+collection of Tensors and `tree_leaves` to get a flat list of all Tensors
+inside some nested collection. pytrees are helpful for implementing nested
+collection support for PyTorch APIs.

+"""
+DebugMode is a debugging TorchDispatchMode that intercepts and logs runtime calls
+to a hierarchical string dump. It logs real tensor, DTensor, and optionally FakeTensor
+operations, with some additional handling for DTensor internals.
+
+An example dump from an eager mode DTensor matmul:
+
+    torch.mm(dt$0: f32[8, 8]| S(0), dt$1: f32[8, 32]| S(0))  ->  dt$6: f32[8, 32]| S(0)
+      aten::mm(dt$0: f32[8, 8]| S(0), dt$1: f32[8, 32]| S(0))
+        redistribute_input(1, S(0) -> R)
+          redistribute_input(t$2: f32[1, 32], trace: S(0)->R)
+            _c10d_functional::all_gather_into_tensor(t$2: f32[1, 32], 8, 0)  ->  t$3: f32[8, 32]
+            _c10d_functional::wait_tensor(t$3: f32[8, 32])  ->  t$3: f32[8, 32]
+        aten::mm(t$4: f32[1, 8], t$3: f32[8, 32])  ->  t$5: f32[1, 32]
+
+This mode runs "under" compile, which means it hides itself during compilation, and is re-enabled
+at runtime, and DebugMode-related operations won't show up in the compiled region.
+DebugMode also provides some visibility into non-torch-dispatch calls (e.g. DTensor redistribute calls,
+inductor-generated triton kernels), but requires special handling for these, since dispatch modes
+can't intercept them by default.
+
+The mode also provides some extensions for custom debugging (e.g. adding custom dispatch call hooks
+via dispatch_hooks), or numerics debugging (e.g. tensor hashing for bitwise equivalence/closeness,
+via log_tensor_hashes). These decorators allow annotating string dumps with additional per-call information,
+for any region of runtime code.
+
+Usage::
+
+    with DebugMode() as debug_mode:
+        result = some_pytorch_operation(tensor_input)
+    print(debug_mode.debug_string())
