ofxLibTorch

Description

an openFrameworks wrapper for LibTorch

Requirements

• Windows10
• Visual Studio 2019
• CUDA v10.1
• openFramewrks v0.11.0
• LibTorch v1.4.0
• ofxOpenCV

Install

1. Download LibTorch from https://pytorch.org/get-started/locally/
2. Unzip the downloaded file and copy the contents of the "include" and "lib" directories to the following location

Windows

• libtorch-win-shared-with-deps-1.4.0/include >> libs/win/include/vs/x64/Release
• libtorch-win-shared-with-deps-1.4.0/lib >> libs/win/lib/vs/x64/Release

macOS

• libtorch-macos-1.4.0/include >> libs/osx/include
• libtorch-macos-1.4.0/lib >> libs/osx/lib

3. In Xcode Build Settings:

   • Under linking -> runpath search paths, add @loader_path/../Frameworks
   • Under search paths -> use header maps, set NO

4. In Xcode Build Phases -> Run Script, add:

rsync -aved "$OF_PATH/addons/ofxLibTorch/libs/osx/lib/libc10.dylib" "$TARGET_BUILD_DIR/$PRODUCT_NAME.app/Contents/Frameworks/";
rsync -aved "$OF_PATH/addons/ofxLibTorch/libs/osx/lib/libtorch.dylib" "$TARGET_BUILD_DIR/$PRODUCT_NAME.app/Contents/Frameworks/";
rsync -aved "$OF_PATH/addons/ofxLibTorch/libs/osx/lib/libtorch_cpu.dylib" "$TARGET_BUILD_DIR/$PRODUCT_NAME.app/Contents/Frameworks/";
rsync -aved "$OF_PATH/addons/ofxLibTorch/libs/osx/lib/libiomp5.dylib" "$TARGET_BUILD_DIR/$PRODUCT_NAME.app/Contents/Frameworks/";

and

install_name_tool -change @rpath/libtorch.dylib @loader_path/../Frameworks/libtorch.dylib "$TARGET_BUILD_DIR/$PRODUCT_NAME.app/Contents/MacOS/$PRODUCT_NAME";
install_name_tool -change @rpath/libtorch_cpu.dylib @loader_path/../Frameworks/libtorch_cpu.dylib "$TARGET_BUILD_DIR/$PRODUCT_NAME.app/Contents/MacOS/$PRODUCT_NAME";
install_name_tool -change @rpath/libc10.dylib @loader_path/../Frameworks/libc10.dylib "$TARGET_BUILD_DIR/$PRODUCT_NAME.app/Contents/MacOS/$PRODUCT_NAME";
install_name_tool -change /DLC/torch/libiomp5.dylib @loader_path/../Frameworks/libiomp5.dylib "$TARGET_BUILD_DIR/$PRODUCT_NAME.app/Contents/MacOS/$PRODUCT_NAME";

before

echo "$GCC_PREPROCESSOR_DEFINITIONS";
