Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/24029 The cmake toolchain file for building iOS is currently in `/third-pary/ios-cmake`. Since the upstream is not active anymore, It's better to maintain this file ourselves moving forward.This PR is also the prerequisite for enabling QNNPACK for iOS. Test Plan: - The `libtorch.a` can be generated successfully - The `libtorch.a` can be compiled and run on iOS devices <img src="https://github.com/xta0/AICamera-ObjC/blob/master/aicamera.gif?raw=true" width="400"> Differential Revision: D16770980 Pulled By: xta0 fbshipit-source-id: 1ed7b12b3699bac52b74183fa7583180bb17567e
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.
