-# TorchFix - a linter for PyTorch-using code with autofix support
-
-TorchFix is a Python code static analysis tool - a linter with autofix capabilities -
-for users of PyTorch. It can be used to find and fix issues like usage of deprecated
-PyTorch functions and non-public symbols, and to adopt PyTorch best practices in general.
-
-TorchFix is built upon https://github.com/Instagram/LibCST - a library to manipulate
-Python concrete syntax trees. LibCST enables "codemods" (autofixes) in addition to
-reporting issues.
-
-TorchFix can be used as a Flake8 plugin (linting only) or as a standalone
-program (with autofix available for a subset of the lint violations).
-
-Currently TorchFix is in a **beta version** stage, so there are still a lot of rough
-edges and many things can and will change.
-
-## Installation
-
-To install the latest code from GitHub, clone/download
-https://github.com/pytorch/test-infra/tree/main/tools/torchfix and run `pip install .`
-inside the directory.
-
-To install a release version from PyPI, run `pip install torchfix`.
-
-## Usage
-
-After the installation, TorchFix will be available as a Flake8 plugin, so running
-Flake8 normally will run the TorchFix linter.
-
-To see only TorchFix warnings without the rest of the Flake8 linters, you can run
-`flake8 --isolated --select=TOR0,TOR1,TOR2`
-
-TorchFix can also be run as a standalone program: `torchfix .`
-Add `--fix` parameter to try to autofix some of the issues (the files will be overwritten!)
-To see some additional debug info, add `--show-stderr` parameter.
-
-Please keep in mind that autofix is a best-effort mechanism. Given the dynamic nature of Python,
-and especially the beta version status of TorchFix, it's very difficult to have
-certainty when making changes to code, even for the seemingly trivial fixes.
-
-Warnings for issues with codes starting with TOR0, TOR1, and TOR2 are enabled by default.
-Warnings with other codes may be too noisy, so not enabled by default.
-To enable them, use standard flake8 configuration options for the plugin mode or use
-`torchfix --select=ALL .` for the standalone mode.
-
-
-## Reporting problems
-
-If you encounter a bug or some other problem with TorchFix, please file an issue on
-https://github.com/pytorch/test-infra/issues, mentioning [TorchFix] in the title.
-
-
-## Rules
-
-### TOR001 Use of removed function
-
-#### torch.solve
-
-This function was deprecated since PyTorch version 1.9 and is now removed.
-
-`torch.solve` is deprecated in favor of `torch.linalg.solve`.
-`torch.linalg.solve` has its arguments reversed and does not return the LU factorization.
-
-To get the LU factorization see `torch.lu`, which can be used with `torch.lu_solve` or `torch.lu_unpack`.
-
-`X = torch.solve(B, A).solution` should be replaced with `X = torch.linalg.solve(A, B)`.
