Install functorch ================= As of PyTorch 1.13, functorch is now included in the PyTorch binary and no longer requires the installation of a separate functorch package. That is, after installing PyTorch (`instructions `_), you'll be able to ``import functorch`` in your program. If you're upgrading from an older version of functorch (functorch 0.1.x or 0.2.x), then you may need to uninstall functorch first via ``pip uninstall functorch``. We've maintained backwards compatibility for ``pip install functorch``: this command works for PyTorch 1.13 and will continue to work for the foreseeable future until we do a proper deprecation. This is helpful if you're maintaining a library that supports multiple versions of PyTorch and/or functorch. Colab ----- Please see `this colab for instructions. `_ Nightly ------- Looking for the newest functorch features? Please download the latest nightly PyTorch binary (``import functorch`` is included in nightly PyTorch binaries as of 09/21/2022). by following instructions `here `_. Previous Versions ----------------- For PyTorch 1.11.x and PyTorch 1.12.x: Please first install PyTorch and then run the following command: :: pip install functorch
