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

Download LibTorch from https://pytorch.org/get-started/locally/
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

In Xcode Build Settings:

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

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";

How can I include the <torch/torch.h> to my OF src file without cmake ?

Hi, @rystylee

How can I include the <torch/torch.h> to my OF src file without cmake ?

I wonder.

Thanks.
Best,
@bemoregt.

Error: No viable overloaded '='

When I try to compile I am stuck with the error No viable overloaded '='.
It appears in BaseModel.cpp in line 18:

mModule = torch::jit::load(modelPath, *mDevice.get());

I am compiling on macOS 10.14.6 with Xcode 10.3.

I see that mModule is a std::unique_ptrm, but from the documentation of torch::jit::load I don't really see if the returned object is also a pointer or something else.
Can you help fix this error?
