(Solved) Enable GPUs for Graxpert on Arch linux

I've been playing with graxpert on Arch linux directly and via siril 1.3.6. The denoise looks interesting, but it is very slow on a CPU. It seems it supports GPUs via Cuda and I have an Nvidia GPU in my laptop that supports Cuda, so I'm hoping I can speed things up.

From a graxpert git page it seems that cuda and libcudnn are the dependencies for linux. I installed them using pacman and tried denoise in graxpert it complained that onnx is missing. When I install onnx (again from pacman) and tried again, this time onnx complained about missing dependencies. From the onnx website it looks like the onnx version (1.17) available for arch is not compatible with the cudnn version from Arch (9.8.0). Alas I can't figure the recipe to get this to work.

If you have successfully enabled GPUs for Graxpert on Linux, could you share how. Thanks

I think you need onnxruntime instead of onnx (if that even exists). It also has a optional cuda dependecy.

Can you post the error messages?

https://github.com/Steffenhir/GraXpert/ … ements.txt lists everything graxpert itself needs .

Are all those installed ?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Those are the requirements for non-cuda. Saw those too.

Re: (Solved) Enable GPUs for Graxpert on Arch linux

GraXpert 3.0.2 has a weird combination of dependencies with cuda 12 and libcudnn8 (default today is 9) due to a onnxruntime dependency. I installed the GraXpert 3.1rc build with the latest cuda, cudnn and onnxruntime, it seems to be running on GPU :-)

cuda 12.8.
cudnn 9.8.0.87
onnxruntime 1.20.2-7
GraXpert version: 3.1.0rc2

Not looking forward to the dependency hell as things update. Makes me really appreciate pacman!

Yes, Graxpert was running on CPU without issue.

I think you are correct, but I couldn't find a onnxruntime build with the older 1.17 version.
