Adds a pre-commit hook (technically a pre-push hook) to the PyTorch repo. **This is currently an opt-in feature**, which one can opt into by running `python scripts/setup_hooks.py` locally. ### Features - **Run Lintrunner Before Push**: Before every `git push`, automatically runs lintrunner on your changes. - Really need to skip the checks? Run `git push --no-verify` - **Consistent, Isolated, Lintrunner Environment**: During pre-push, Lintrunner runs in it's own virtual en environment that contain all lintrunner dependencies in a consistent, isolated environment. No more lintrunner failures because you created a new .venv. (Did you know you needed to run `lintrunner init` every time you make a new .venv?) - **Dependencies Automatically Updated**: If .lintrunner.toml is updated, this will automatically re-run `lintrunner init` to ensure you install the latest dependencies specified ### Installation - Run `python scripts/setup_hooks.py`. Now every `git push` will first run lintrunner. ### Additional details - The lintrunner used by the pre-push hook runs in a special per-repo virtual environment managed by the commit-hook tool located under `$USER/.cache/pre-commit` - Does not affect your regularly used lintrunner - Manual invocations of lintrunner will continue to depend on your local environment instead of the special pre-push one. If there's enough interest, we could explore consolidating them. - Does not run `lintrunner -a` for you. - You still need to manually run that (can be changed later though!) - Have staged/unstaged changes? No worries - This runs `git stash` before running the pre-commit hooks and pops back your changes afterwards, so only the changes actaully being pushed will be tested ### Downsides - No streaming UI updates - While you still get the same output from lintrunner that you're used to, the commit-hook framework doesn't show any output while lintrunner is actually running. Instead, it shows the entire output after linter has completed execution, which could be a few minutes (especially if it has to run `lintrunner init` first) - `uv` installation is required to run the setup script. The setup script will ask users to install uv if it's not available. - This is required to be able to install the pre-commit package in a safe way that's available no matter what .venv you are running in. ### Opting out - Disable hook for a single push: Run `git push --no-verify` - Disable hook permanently: If something goes wrong and you need to wipe your setup: - Delete the `$USER/.cache/pre-commit` folder and the `.git/hooks/pre-push` file in your local repo. - You can now rerun `python scripts/setup_hooks.py` to setup your git push hook again if you want. ### Potential Future Changes Things that could be done to make this even better if folks like these ideas: - Automatic setup - Our `CONTRIBUTING.md` file tells devs to run `make setup-env`. That could be a good entry point to hook the installation into - Fix the console output streaming - Make every lintrunner invocation (including manual ones) use the same repo-specific venv that the commit-hook uses.

build_android.sh
This script is to build PyTorch/Caffe2 library for Android. Take the following steps to start the build:
- set ANDROID_NDK to the location of ndk
export ANDROID_NDK=YOUR_NDK_PATH
- run build_android.sh
#in your PyTorch root directory
bash scripts/build_android.sh
If succeeded, the libraries and headers would be generated to build_android/install directory. You can then copy these files from build_android/install to your Android project for further usage.
You can also override the cmake flags via command line, e.g., following command will also compile the executable binary files:
bash scripts/build_android.sh -DBUILD_BINARY=ON
build_ios.sh
This script is to build PyTorch/Caffe2 library for iOS, and can only be performed on macOS. Take the following steps to start the build:
- Install Xcode from App Store, and configure "Command Line Tools" properly on Xcode.
- Install the dependencies:
brew install cmake automake libtool
- run build_ios.sh
#in your PyTorch root directory
bash scripts/build_ios.sh
If succeeded, the libraries and headers would be generated to build_ios/install directory. You can then copy these files to your Xcode project for further usage.
