+In PyTorch, we enforce lint rules on code in order to help us catch common mistakes and enforce a greater degree of uniformity in our codebase than human reviewers can normally enforce.

 PyTorch uses `lintrunner` to execute lints locally and in CI. This provides developers with a single command to run all the linters, and ensures consistency between the CI and local development environments. See [the `lintrunner` repo](https://github.com/suo/lintrunner) for more info.
 
 To get started, run the following to install `lintrunner`. Make sure you are at the root of the PyTorch repo:
