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
  1. In Xcode Build Settings:
  • Under linking -> runpath search paths, add @loader_path/../Frameworks
  • Under search paths -> use header maps, set NO
  1. 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";
