+Python shell for SymPy.
+
+This is just a normal Python shell (IPython shell if you have the
+IPython package installed), that executes the following commands for
+the user:
+
+    >>> from __future__ import division
+    >>> from sympy import *
+    >>> x, y, z, t = symbols('x y z t')
+    >>> k, m, n = symbols('k m n', integer=True)
+    >>> f, g, h = symbols('f g h', cls=Function)
+    >>> init_printing()
+
+So starting 'isympy' is equivalent to starting Python (or IPython) and
+executing the above commands by hand.  It is intended for easy and quick
+experimentation with SymPy.  isympy is a good way to use SymPy as an
+interactive calculator. If you have IPython and Matplotlib installed, then
+interactive plotting is enabled by default.
+
+COMMAND LINE OPTIONS
+--------------------
+
+-c CONSOLE, --console=CONSOLE
+
+     Use the specified shell (Python or IPython) shell as the console
+     backend instead of the default one (IPython if present, Python
+     otherwise), e.g.:
+
+        $isympy -c python
+
+    CONSOLE must be one of 'ipython' or 'python'
+
+-p PRETTY, --pretty PRETTY
+
+    Setup pretty-printing in SymPy. When pretty-printing is enabled,
+    expressions can be printed with Unicode or ASCII. The default is
+    to use pretty-printing (with Unicode if the terminal supports it).
+    When this option is 'no', expressions will not be pretty-printed
+    and ASCII will be used:
+
+        $isympy -p no
+
+    PRETTY must be one of 'unicode', 'ascii', or 'no'
+
+-t TYPES, --types=TYPES
+
+    Setup the ground types for the polys.  By default, gmpy ground types
+    are used if gmpy2 or gmpy is installed, otherwise it falls back to python
+    ground types, which are a little bit slower.  You can manually
+    choose python ground types even if gmpy is installed (e.g., for
+    testing purposes):
+
+        $isympy -t python
+
+    TYPES must be one of 'gmpy', 'gmpy1' or 'python'
+
+    Note that the ground type gmpy1 is primarily intended for testing; it
+    forces the use of gmpy version 1 even if gmpy2 is available.
+
+    This is the same as setting the environment variable
+    SYMPY_GROUND_TYPES to the given ground type (e.g.,
+    SYMPY_GROUND_TYPES='gmpy')
+
+    The ground types can be determined interactively from the variable
+    sympy.polys.domains.GROUND_TYPES.
+
+-o ORDER, --order ORDER
+
+    Setup the ordering of terms for printing.  The default is lex, which
+    orders terms lexicographically (e.g., x**2 + x + 1). You can choose
+    other orderings, such as rev-lex, which will use reverse
+    lexicographic ordering (e.g., 1 + x + x**2):
+
+        $isympy -o rev-lex
+
+    ORDER must be one of 'lex', 'rev-lex', 'grlex', 'rev-grlex',
+    'grevlex', 'rev-grevlex', 'old', or 'none'.
+
+    Note that for very large expressions, ORDER='none' may speed up
+    printing considerably but the terms will have no canonical order.
+
+-q, --quiet
+
+    Print only Python's and SymPy's versions to stdout at startup.
+
+-d, --doctest
+
+    Use the same format that should be used for doctests.  This is
+    equivalent to -c python -p no.
+
+-C, --no-cache
+
+    Disable the caching mechanism.  Disabling the cache may slow certain
+    operations down considerably.  This is useful for testing the cache,
+    or for benchmarking, as the cache can result in deceptive timings.
+
+    This is equivalent to setting the environment variable
+    SYMPY_USE_CACHE to 'no'.
+
+-a, --auto-symbols (requires at least IPython 0.11)
+
+    Automatically create missing symbols.  Normally, typing a name of a
+    Symbol that has not been instantiated first would raise NameError,
+    but with this option enabled, any undefined name will be
+    automatically created as a Symbol.
+
+    Note that this is intended only for interactive, calculator style
+    usage. In a script that uses SymPy, Symbols should be instantiated
+    at the top, so that it's clear what they are.
+
+    This will not override any names that are already defined, which
+    includes the single character letters represented by the mnemonic
+    QCOSINE (see the "Gotchas and Pitfalls" document in the
+    documentation). You can delete existing names by executing "del
+    name".  If a name is defined, typing "'name' in dir()" will return True.
+
+    The Symbols that are created using this have default assumptions.
+    If you want to place assumptions on symbols, you should create them
+    using symbols() or var().
+
+    Finally, this only works in the top level namespace. So, for
+    example, if you define a function in isympy with an undefined
+    Symbol, it will not work.
+
+    See also the -i and -I options.
+
+-i, --int-to-Integer (requires at least IPython 0.11)
+
+    Automatically wrap int literals with Integer.  This makes it so that
+    things like 1/2 will come out as Rational(1, 2), rather than 0.5.  This
+    works by preprocessing the source and wrapping all int literals with
+    Integer.  Note that this will not change the behavior of int literals
+    assigned to variables, and it also won't change the behavior of functions
+    that return int literals.
+
+    If you want an int, you can wrap the literal in int(), e.g. int(3)/int(2)
+    gives 1.5 (with division imported from __future__).
+
+-I, --interactive (requires at least IPython 0.11)
+
+    This is equivalent to --auto-symbols --int-to-Integer.  Future options
+    designed for ease of interactive use may be added to this.
+
+-D, --debug
+
+    Enable debugging output.  This is the same as setting the
+    environment variable SYMPY_DEBUG to 'True'.  The debug status is set
+    in the variable SYMPY_DEBUG within isympy.
+
+-- IPython options
+
+    Additionally you can pass command line options directly to the IPython
+    interpreter (the standard Python shell is not supported).  However you
+    need to add the '--' separator between two types of options, e.g the
+    startup banner option and the colors option. You need to enter the
+    options as required by the version of IPython that you are using, too:
+
+    in IPython 0.11,
+
+        $isympy -q -- --colors=NoColor
+
+    or older versions of IPython,
+
+        $isympy -q -- -colors NoColor
+
+See also isympy --help.

+
+Use W&B to build better models faster. Track and visualize all the pieces of your machine learning pipeline, from datasets to production machine learning models. Get started with W&B today, [sign up for an account!](https://wandb.com?utm_source=github&utm_medium=code&utm_campaign=wandb&utm_content=readme)
+
+
+
+See the [W&B Developer Guide](https://docs.wandb.ai/?utm_source=github&utm_medium=code&utm_campaign=wandb&utm_content=documentation) and [API Reference Guide](https://docs.wandb.ai/ref?utm_source=github&utm_medium=code&utm_campaign=wandb&utm_content=documentation) for a full technical description of the W&B platform.
+
+&nbsp;
+
+# Quickstart
+
+Get started with W&B in four steps:
+
+1. First, sign up for a [W&B account](https://wandb.ai/login?utm_source=github&utm_medium=code&utm_campaign=wandb&utm_content=quickstart).
+
+2. Second, install the W&B SDK with [pip](https://pip.pypa.io/en/stable/). Navigate to your terminal and type the following command:
+
+```shell
+pip install wandb
+```
+
+3. Third, log into W&B:
+
+```python
+wandb.login()
+```
+
+4. Use the example code snippet below as a template to integrate W&B to your Python script:
+
+```python
+import wandb
+
+# Start a W&B Run with wandb.init
+run = wandb.init(project="my_first_project")
+
+# Save model inputs and hyperparameters in a wandb.config object
+config = run.config
+config.learning_rate = 0.01
+
+# Model training code here ...
+
+# Log metrics over time to visualize performance with wandb.log
+for i in range(10):
+    run.log({"loss": ...})
+
+# Mark the run as finished, and finish uploading all data
+run.finish()
+```
+
+For example, if the preceding code was stored in a script called train.py:
+
+```shell
+python train.py
+```
+
+You will see a URL in your terminal logs when your script starts and finishes. Data is staged locally in a directory named _wandb_ relative to your script. Navigate to the W&B App to view a dashboard of your first W&B Experiment. Use the W&B App to compare multiple experiments in a unified place, dive into the results of a single run, and much more!
+
+&nbsp;
+
+# Integrations
+
+Use your favorite framework with W&B. W&B integrations make it fast and easy to set up experiment tracking and data versioning inside existing projects. For more information on how to integrate W&B with the framework of your choice, see [W&B Integrations](https://docs.wandb.ai/guides/integrations) in the W&B Developer Guide.
+
+&nbsp;
+
+# Python Version Support
+
+We are committed to supporting our minimum required Python version for *at least* six months after its official end-of-life (EOL) date, as defined by the Python Software Foundation. You can find a list of Python EOL dates [here](https://devguide.python.org/versions/).
+
+When we discontinue support for a Python version, we will increment the library’s minor version number to reflect this change.
+
+&nbsp;

+"""A PEP 517 interface to setuptools
+
+Previously, when a user or a command line tool (let's call it a "frontend")
+needed to make a request of setuptools to take a certain action, for
+example, generating a list of installation requirements, the frontend would
+would call "setup.py egg_info" or "setup.py bdist_wheel" on the command line.
+
+PEP 517 defines a different method of interfacing with setuptools. Rather
+than calling "setup.py" directly, the frontend should:
+
+  1. Set the current directory to the directory with a setup.py file
+  2. Import this module into a safe python interpreter (one in which
+     setuptools can potentially set global variables or crash hard).
+  3. Call one of the functions defined in PEP 517.
+
+What each function does is defined in PEP 517. However, here is a "casual"
+definition of the functions (this definition should not be relied on for
+bug reports or API stability):
+
+  - `build_wheel`: build a wheel in the folder and return the basename
+  - `get_requires_for_build_wheel`: get the `setup_requires` to build
+  - `prepare_metadata_for_build_wheel`: get the `install_requires`
+  - `build_sdist`: build an sdist in the folder and return the basename
+  - `get_requires_for_build_sdist`: get the `setup_requires` to build
+
+Again, this is not a formal definition! Just a "taste" of the module.

+A lightweight wrapper around Python's sqlite3 database, with a dict-like interface
+and multi-thread access support::
+
+>>> mydict = SqliteDict('some.db', autocommit=True) # the mapping will be persisted to file `some.db`
+>>> mydict['some_key'] = any_picklable_object
+>>> print mydict['some_key']
+>>> print len(mydict) # etc... all dict functions work
+
+Pickle is used internally to serialize the values. Keys are strings.
+
+If you don't use autocommit (default is no autocommit for performance), then
+don't forget to call `mydict.commit()` when done with a transaction.

+        The `decode` function must be a function that takes the serialized
