ONNX runtime for node with gpu support (DirectML/Cuda)
Info
This is an updated copy of official onnxruntime-node with DirectML and Cuda support.
Requirements
Windows
- Works out of the box with DirectML. You can install CUDA and onnx runtime for windows with cuda provider for experiments, if you like.
Linux / WSL2
- Install CUDA (tested only on 11-7 but 12 should be supported) https://docs.nvidia.com/cuda/cuda-installation-guide-linux/
- Install onnxruntime-linux-x64-gpu-1.14.1 https://github.com/microsoft/onnxruntime/releases/tag/v1.14.1
Limitations
- Currently, all results are returned as NAPI nodejs objects, so when you run inference multiple times (e.g. sampling on StableDiffusion Unet), there are a lot of unnecessary memory copy operations input from js to gpu and back. However, performance impact is not big. Maybe later I will make output in Tensorflow.js compatible tensors
Building manually
Just download the repo and run npx cmake-js compile
Why is onnxruntime statically linked on Windows?
For some reason, dynamically linked onnx runtime tries to load outdated DirectML.dll in system32, see https://github.com/royshil/obs-backgroundremoval/issues/272
Misc
Special thanks to authors of https://github.com/royshil/obs-backgroundremoval and https://github.com/umireon/onnxruntime-static-win for CMake scripts to download pre-built onnxruntime for static linking.
Also thanks to ChatGPT for helping me to remember how to code in c++.
