+  // Note: Gradient Layout Contract

+  // AccumulateGrad tries to stash strided (non-sparse) grads with memory layout
+  // (strides) such that variables and grads interact efficiently in later
+  // optimizer kernels, and grads interact efficiently with c10d::Reducer.cpp.
+  //
+  // Specifically, AccumulateGrad tries to ensure the following
+  // (cf torch/csrc/autograd/utils/grad_layout_contract.h):
+  //   (1) if variable.is_non_overlapping_and_dense(), the stashed grad's
+  //       strides match variable.
+  //   (2) else, stashed grad is rowmajor contiguous.
+  // If variable's grad does not exist (!variable_grad.defined())
+  // AccumulateGrad steals new_grad if it's stealable and obeys the contract
+  // already, otherwise it deep copies new_grad into an obedient clone.
+  //
+  // If variable's grad already exists (variable_grad.defined()), new_grad must
+  // be added to variable_grad.  If we aren't setting up for double backward
+  // (!GradMode::is_enabled()), AccumulateGrad performs "variable_grad +=
+  // new_grad" in-place, which keeps variable_grad's layout. We assume (hope)
+  // variable_grad was created obeying (1) or (2) at some point in the past.
+  //
+  // If we are setting up for double backward, AccumulateGrad updates the grad
+  // out-of-place via "variable_grad + new_grad."  TensorIterator operator+
+  // decides result's layout.  Typically TensorIterator matches strides of the
+  // first arg, so we once again assume (hope) variable_grad was originally
+  // created obeying (1) or (2).
+  //
+  // AccumulateGrad does not enforce the contract with 100% certainty. Examples:
+  //  - If a user manually permutes a param or its grad, then runs a fwd+bwd,
+  //    variable_grad += new_grad keeps variable_grad's layout without
+  //    rechecking the contract.
+  //  - If TensorIterator changes its corner cases about operator+'s result
+  //    (for example, giving more or less priority to channels_last inputs, see
+  //    https://github.com/pytorch/pytorch/pull/37968) the result may not obey.
+  //
+  // Fortunately, if a given grad doesn't satisfy (1) or (2), the penalty is
+  // degraded performance in Reducer.cpp or optimizer kernels, not death by
+  // assert or silently bad numerics.
+
+  // Gradient Accumulation
+  // Given a variable with its current grad as variable_grad, accumulates
+  // new_grad into variable_grad if in place accumulation is possible.
+  // Otherwise, uses 'update_grad' to update the grad for the variable.
+  //
+  // Branch breakdown:
+  // - Case 1: Param has no existing grad
+  //   - Case 1.1: Stealable dense new_grad
+  //     . We aren't setting up for double-backward.
+  //     . No other user-visible tensor references new_grad.
+  //     . new_grad obeys the "Gradient Layout Contract", there has a special
+  //       case, For MKLDNN tensor, which is a opaque tensor, assuming it obeys
+  //       layout_contract.
+  //   - Case 1.2: Stealable sparse new_grad
+  //     . Can't detach sparse tensor (since metadata changes are not allowed
+  //       after detach), so just create a new one for the grad which is a
+  //       shallow copy. We need a shallow copy so that modifying the original
+  //       grad tensor doesn't modify the grad we accumulate.
+  //     . We only skip clone if indices and values themselves are contiguous
+  //       for backward compatibility reasons. Since without this optimization,
+  //       earlier we would clone the entire SparseTensor which cloned indices
+  //       and values. For details see
+  //       https://github.com/pytorch/pytorch/issues/34375.
+  //   - Case 1.3: Cloning sparse/nested new_grad
+  //   - Case 1.4: Cloning MKLDNN new_grad
+  //   - Case 1.5: Deep copies new_grad according to the Gradient Layout
+  //   Contract.
+  // - Case 2: Param has existing grad and grad mode is not enabled
+  //   - This case is not strictly necessary, but it makes the first-order only
+  //     case slightly more efficient.
+  //   - Case 2.1: Sparse variable_grad + Dense new_grad
+  //     . If `variable_grad` is sparse and `new_grad` is not sparse, their
+  //       sum is not sparse, and we must change the TensorImpl type of
+  //       `variable_grad` for it to store the result. However, changing the
+  //       TensorImpl type of a tensor requires changing the tensor itself, and
+  //       thus in this case we have to change the grad tensor.
+  //   - Case 2.2: Vmap-incompatible
+  //     . Ideally we'd perform an in-place operation to avoid changing
+  //       the grad tensor. However, if that's impossible because the grads
+  //       are vmap-incompatible (See NOTE: [vmap-incompatible in-place
+  //       operations]), then we just add them out-of-place.
+  //   - Case 2.3: In-place addition
+  //     . In this case we can avoid changing the grad tensor. There are three
+  //       scenarios when we'll hit this case:
+  //       . `variable_grad` is sparse, and `new_grad` is sparse.
+  //       . `variable_grad` is dense, and `new_grad` is sparse.
+  //       . `variable_grad` is dense, and `new_grad` is dense.
+  //       . `variable_grad` is mkldnn, and `new_grad` is mkldnn.
+  //
+  //       In all of these four cases, `variable_grad += new_grad` is a
+  //       valid operation which adds `new_grad` to `variable_grad` in
+  //       place. `variable_grad` is thus still referring to the same tensor
+  //       after the operation.
+  //     . DistributedDataParallel(DDP) package relies on grad being
+  //       mutated in place for saving peak memory usage. DDP will still
+  //       work correctly if it is mutated out of place here, but DDP will
+  //       maintain one extra copy of grad tensors in buffer and thus
+  //       increase peak memory usage.
+  // - Case 3: Param has existing grad and grad mode is enabled
+  //   - Case 3.1: Sparse variable_grad + Dense new_grad
+  //   - Case 3.2: Not Sparse variable_grad + Dense new_grad
+  //
+  // variable: the variable whose grad we're accumulating.
+  // variable_grad: the current grad for the variable.

+//   - It explains what is the CopySlices Node and why we need it.
+//   - It explains the considerations on what is saved for backward in
+//   CopySlices.
+//   - It explains why we need to sometimes change the exec_info of the current
+//   backward
+//
+// What is CopySlices?
+// ~~~~~~~~~~~~~~~~~~~
+//
+// We support autograd with inplace mutation; e.g., if you write x.mul_(2)
+// the autograd will work as if you now had multiple Tensors under the hood and
+// you did
+//   x = t.clone()
+//   x0 = x
+//   x1 = x0 * 2
+//   x = x1
+// As you can see here, after this operation, x.grad_fn now points to x1.grad_fn
+// (the MulBackward node) and this node points to x's original grad_fn (which is
+// also x0.grad_fn). It is important to keep in mind that after the inplace,
+// there is no Tensor object that represents the x0 state anymore. But the graph
+// for it is still around in autograd (in case x was used before being modified
+// inplace). See Example 1 in
+// https://docs.google.com/drawings/d/1-T5DyYfChMX1ONQkY-zU-hj_ayQ2zmA5CBOKDWqvEhE
+// We call this rebasing the history of the Tensor.
+//
+// Now, a difficult situation is what happens if x is a differentiable view
+// of a base b.
+//   b = t.clone()
+//   x = b.select(0, 0)
+//   x *= 2
+// With the same approach as above, this will become
+//   b = t.clone()
+//   x = b.select(0, 0)
+//   b0 = b
+//   x0 = x
+//   x1 = x0 * 2
+//   b1 = b0.select_scatter(x1, 0, 0)
+//   x2 = b1.select(0, 0)
+//   x = x2
+//   b = b1
+// As you can see here, not only we need to modify x's grad_fn, we also need to
+// modify the one from b. We also need to ensure that the new grad_fn on x is
+// linked to b's new grad_fn. The chain the select_scatter, multiplication and
+// select is what CopySlices does, all wrapped into a single Node.
+//
+// See Example 1 in
+// https://docs.google.com/drawings/d/1-T5DyYfChMX1ONQkY-zU-hj_ayQ2zmA5CBOKDWqvEhE
+//
+// What do we need to save in CopySlices to run backward?
+// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+//
+// We need to perform grad_view = fn(grad_view), but out-of-place.
+// view_fn_ is an optional function saved in DifferentiableViewMeta
+// from forward pass, so that we can recover we when as_strided is not
+// supported. It preserves the invariants:
+//   view = view_fn_(base)
+//   grad_view = view_fn_(grad_base)
+//
+// When as_strided is supported (e.g. strided CPU/CUDA Tensors), view_fn_
+// is empty and we save TensorGeometry(view) instead.
+// With the TensorGeometry information we can use `as_strided` call which
+// is more efficient to recover views in backward.
+//
+// For example:
+//   view_1 = view_op_1(base)
+//   view_2 = view_op_2(view_1)
+//   ...
+//   view_n = view_op_n(view_n-1)
+//   view_n = inplace_op(view_n)
+//
+// In CPU/CUDA case where we support efficient as_strided implementation,
+// grad_view_n can be calculated through 1 step.
+//
+//   grad_view_n = grad_base.as_strided(view_sizes, view_strides, view_offset);
+//
+// But in XLA backend where we don't have full support of as_strided,
+// it has to save a chained lambda function view_fn_, to exactly
+// replay how the view was done in forward.
+//
+//   view_fn_ = view_op_n(...(view_op_2(view_op_1())))
+//   grad_view_n = view_fn_(grad_base)
+//
+// This chain view_fn_ works as long as forward view ops are implemented,
+// e.g XLA simulates view without a real Storage behind Tensor, but it's less
+// efficient than the as_strided one so we should be careful to only use it when
+// necessary.
+//
+//   - For CPU/CUDA we save TensorGeometry of both base and view tensors,
+//     That's all we need to pass into as_strided.
+//     E.g. int[] sizes, int[] strides, and int storage_offset.
+//   - For XLA we use view_fn_, which captures all forward view op arguments
+//     by **value**.
+//     E.g for at::narrow, int dim, int start, in length are saved.
+//
+// Theoretically we could also save Tensor `view` in CopySlices Node, but
+// it's far more expensive than what we currently save.
+//   1. We cannot afford keeping large tensors alive to recover views only.
+//   2. There are inplace checks when Tensors are loaded back to make sure
+//      they haven't been changed (including size metadata).
+// So saving metadata like TensorGeometry/view arguments is much better
+// because it is minimal information needed to recover views, as well as it
+// allows the user to modify the original Tensor without preventing the
+// backward pass from running.
+//
+// Why do we manually change exec_info in the apply?
+// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+//
+// Using the same example as before,
+//   b = t.clone()
+//   x = b.select(0, 0)
+//   x *= y
+//
+// You can see the visualization at
+// https://docs.google.com/drawings/d/1Bx-Hcz-zlIv7PabQqnPhUIVIs9F8WWi48svqMsAUMFs
+// which contains the wrapped MulBackward Node and show what it links to.
+// Since a backward can happen between any subset of the inputs (t and y) and
+// outputs (o, x, b). It is possible to get into a state where CopySlices's 0th
+// next function (CloneBackward) needs gradient but MulBackward's 0th next
+// function (SelectBackward) is not. This happens if you do autograd.grad
+// between x and t for example.
+// In such a case, we do need to mark SelectBackward as requiring gradient such
+// that, during the execution of MulBackward, we will actually compute gradient
+// for the 0th input.
+//
+// All the other next functions are always shared (this is asserted in the apply
+// code) and so nothing needs to be done for them.
+
+// See Note [View + Inplace update for view tensor] for what we do to view
+// tensor when an in-place operation happens.

+///~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///                                Variable
+///~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+/// A `Variable` augments a `Tensor` with the ability to interact in our
+/// autograd machinery. Conceptually, `Variable`s travel along `Edge`s between
+/// `Node`s in the autograd graph. A `Variable` can either be a leaf, like a
+/// weight in a neural network, or an interior variable, when it is the result
+/// of an operation between variables. Every `Variable` also stores another
+/// `Variable` called its `grad` (gradient). If the variable is a leaf, its
+/// gradient will be accumulated into this variable.
+///
+/// Every Tensor is a Variable, but sometimes we colloquially refer to Variables
+/// that don't require gradients as Tensors (since none of the autograd
+/// machinery for Variables applies).  Historically, Variables and Tensors
+/// were separate concepts, but now they are exactly the same (i.e. we have
+/// `using Variable = at::Tensor`).
+///
+///                              Gradient Edges
+///~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+/// Furthermore, `Variable`s have the notion of a `gradient_edge`, which is the
+/// edge in the autograd graph that connects the variable to a particular input
+/// of the gradient function that will be invoked with the variable during the
+/// backward pass. More precisely, this gradient function can be one of two
+/// things:
+/// 1. A `grad_fn`, if the variable is in the interior of the graph. This is the
+///    gradient of the function that produced the variable.
+/// 2. A `grad_accumulator`, if the variable is a leaf, which accumulates a
+///    scalar gradient value into its `grad` variable.
+///
+///                               Versioning
+///~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+/// Another major feature of `Variable`s are *versions*. Versions are
+/// incremented when an in-place mutation of a variable occurs. Versions are
+/// useful when constructing `SavedVariable`s, which take a snapshot of a
+/// `Variable` at a certain version. You can retrieve a `Variable`'s version
+/// through its `current_version()` method.
+///
+///                                 Views
+///~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+/// It is possible for a  `Variable` to be a *view* of another `Variable`, in
+/// which case it tracks that `Variable`'s data and autograd history. Beyond
+/// construction, the interface of a view is identical to that of a regular
+/// `Variable`. You can determine whether `Variable` is in fact a view by
+/// probing its `is_view()` method. Note that the *view* semantics are only
+/// meaningful for `Variable` relations that are relevant to autograd.
+/// See NOTE [ Autograd View Variables ] for more details.

+//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+/// NOTE [ Autograd View Variables ]
+///
+/// Many operations return Variable that shares storage with an input Variable.
+/// The returned Variable is called a **view** Variable on the input **base**
+/// Variable.
+///
+/// In PyTorch, we have two types of views: differentiable views, and
+/// non-differentiable views. In either type, to support proper version
+/// checking, the base and view Variables must always share the same
+/// version_counter.
+///
+///
+/// Differentiable Views
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+/// This class allows to track both forward and backward AD differentiable
+/// views. These views can have different base as non-differentiable view for
+/// forward and backward mode AD are not the same.
+///
+/// Most function are either both forward and backward differentiable views (for
+/// example: view, select, narrow, transpose, etc) or both not forward and not
+/// backward differentiable views (for example: indices, values, eq, lt, etc).
+/// But there are also functions that are forward but not backward
+/// differentiable views (only detach for now) or functions that are backward
+/// but not forward differentiable view (only make_dual and unpack dual for
+/// now).
+///
+/// A concrete example of two views with different bases is as follow:
+///
+///     # Have:
+///     #   dual is a dual Tensor that is neither a forward or backward view
+///     detached_dual = dual.detach()
+///     view = detached_dual.view_as(dual)
+///     # The forward base of view is dual
+///     # The backward base of view is detached_dual
+///
+/// - Backward Mode View
+/// Differentiable views are the view variables where you want gradients to flow
+/// back to the base variables. Out-of-place operations on views are quite
+/// straightforward, but in-place ones are very tricky. Even if the base
+/// variable may not require grad when we create the view, we still need to
+/// track the view relation because future in-place ops may require back-proping
+/// through it. For example, we need to support
+///
+///   (1) in-place operation on view, e.g.,
+///
+///     # Have:
+///     #   base.requires_grad = False
+///     #   var.requires_grad = True
+///     base[1] = var  # i.e., base[1].copy_(var)
+///     torch.autograd.grad(base.sum(), var)  <- should return an all ones
+///     tensor
+///
+///   (2) in-place operation on base after view is created, e.g.,
+///
+///     # Have:
+///     #   base.requires_grad = False
+///     #   var.requires_grad = True
+///     view = base[1]
+///     base.copy_(var)
+///     torch.autograd.grad(view.sum(), var)  <- should return a tensor with
+///                                              var[1] filled with all ones and
+///                                              zeros everywhere else
+///
+/// - Forward Mode View
+/// Forward differentiable views follow the same semantic as backward ones but
+/// show up differently as they are computed along with the forward evaluation.
+/// The hard examples above are thus very similar
+///
+///   (1) in-place operation on view, e.g.,
+///
+///     # Have:
+///     #   base is a regular Tensor
+///     #   var is a dual Tensor whose tangent is all ones
+///     base[1] = var  # i.e., base[1].copy_(var)
+///     # Now, base is a dual Tensor
+///     _, fw_grad = fwAD.unpack_dual(base) <- fw_grad should be a tensor with
+///                                              fw_grad[1] filled with all ones
+///                                              and zeros everywhere else
+///
+///   (2) in-place operation on base after view is created, e.g.,
+///
+///     # Have:
+///     #   base is a regular Tensor
+///     #   var is a dual Tensor whose tangent is all ones
+///     view = base[1]
+///     base.copy_(var)
+///     _, fw_grad = fwAD.unpack_dual(view) <- fw_grad should be an all ones
+///     tensor
+///
+/// See Note [Forward Grad View/inplace] for more details on how we handle these
+/// hard cases.
+///
+///
+/// DifferentiableViewMeta is created to support gradient tracking of
+/// such **in-place** operations. In particular,
+///   + if an in-place op is done on base, the grad_fn field of the view may
+///     become stale. So accesses should always go through grad_fn(), which
+///     reconstructs an updated grad_fn if the version_counter has incremented.
+///     All other fields are always valid.
+///   + if an in-place op is done on view, in rebase_history() of view, which is
+///     called after every in-place op in VariableType.cpp, the grad_fn of base
+///     is updated.
+///   + if a single autograd Node returns multiple differentiable views, if any
+///     output is modified by an inplace operation, the autograd engine will
+///     make an equivalent graph (corresponding to the view operations) without
+///     using equivalent graph, where each output is treated as if it were
+///     produced by a distinct view operation. This discards the original (e.g.,
+///     user provided) grad_fn. If the provided grad_fn does more than the
+///     backward of the view, then the DifferentiableViewMeta must be created
+///     with creation_meta= CreationMeta::MULTI_OUTPUT_NODE to prevent the
+///     engine from ignoring the provided grad_fn.
+///
+/// Interaction with GradMode:
+/// The particular case that we consider here is:
+///
+///     # Have:
+///     #   base.requires_grad = True or False
+///     with torch.no_grad():
+///         view = base[1]
+///     base.requires_grad_()
+///     view.copy_(var)
+///     torch.autograd.grad(base.sum(), var)  <- what should it return?
+///
+/// Given that this particular code example is ambiguous and can easily be
+/// replace by either moving both inside the no_grad block or both outside, we
+/// explicitly forbid it. For now, it is deprecated by a warning. This is
+/// achieved by setting creation_meta=CreationMeta::NO_GRAD_MODE for all
+/// differentiable views created in no_grad mode.
+///
+/// See Note [View + Inplace update for base tensor]
+/// and Note [View + Inplace update for view tensor] for the details how
+/// autograd handles inplace update with view ops.
+///
+/// Non-Differentiable Views
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+/// In certain cases, although function outputs share storage with inputs, they
+/// will **never** require gradient history tracking. Instead of registering the
+/// view relation via DifferentiableViewMeta in autograd, the views will be
+/// using usual AutogradMeta and just share the version counters with the base
+/// Variables.
+/// Such views include:
+///   1. Views created from .detach()
+///   2. Views that are non-differentiable by its nature.
+///      E.g., `sparse_tensor.indices()` is a integral view on a (possibly)
+///      floating point tensor.
+///      See top of `derivatives.yaml` on how to specify that outputs of a
+///      function are non-differentiable.
+/// These are called non-differentiable views as the gradients do not flow
+/// through the view relation.
+///
+/// Relevant logic for both differentiable and non-differentiable views is
+/// implemented in make_variable_(non_)differentiable_view below, and
+/// wrap_output of gen_variable_type.py.
+
+/// NOTE [ View + Inplace detection ]
+///
+/// We want to detect views followed by inplace as they are often forbidden to
+/// ensure correctness of the computed gradients. But since we want to only
+/// notify the user when both happen, we tag the DifferentiableViewMeta when the
+/// view is created via the `make_variable_*_view()` functions. This tag is then
+/// checked by the `check_inplace()` function from `VariableTypeUtils.h` that
+/// should be called before every inplace operation and to detect cases where
+/// other views are modified and this one is rebased by side effect, we also
+/// check in the `VariableHooks::grad_fn()`.
+
+/// Flag that gives more information about when this view was created:
+/// - IN_CUSTOM_FUNCTION should be set when the view is created inside a custom
+///   autograd Function is returned.
+/// - NO_GRAD_MODE should be set when a view in created when GradMode is
+/// disabled
+/// - MULTI_OUTPUT_NODE should be set when a Node created by codegen code
+/// returns
+///   multiple differentiable views
+/// - Inference_MODE should be set when a view of normal tensor is created in
+/// InferenceMode.
+/// - DEFAULT is for all other cases
