Xuehai Pan 2293fe1024 [BE][Easy] use pathlib.Path instead of dirname / ".." / pardir (#129374)
Changes by apply order:

1. Replace all `".."` and `os.pardir` usage with `os.path.dirname(...)`.
2. Replace nested `os.path.dirname(os.path.dirname(...))` call with `str(Path(...).parent.parent)`.
3. Reorder `.absolute()` ~/ `.resolve()`~ and `.parent`: always resolve the path first.

    `.parent{...}.absolute()` -> `.absolute().parent{...}`

4. Replace chained `.parent x N` with `.parents[${N - 1}]`: the code is easier to read (see 5.)

    `.parent.parent.parent.parent` -> `.parents[3]`

5. ~Replace `.parents[${N - 1}]` with `.parents[${N} - 1]`: the code is easier to read and does not introduce any runtime overhead.~

    ~`.parents[3]` -> `.parents[4 - 1]`~

6. ~Replace `.parents[2 - 1]` with `.parent.parent`: because the code is shorter and easier to read.~

This directory contains the useful tools.

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.
