[Bug]: RX 6750 XT not supported [Arch Linux]

[PrintStringName]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits

What happened?

Torch does not detect RX 6750 XT for GPU acceleration, giving the dreaded "Torch is not able to use GPU" error. Worked when I tried it a few months ago, but seems to be broken now. This is on a clean install.

sysinfo file anonymised to remove name.

Steps to reproduce the problem

1. Follow installation instructions for Arch + AMD GPU
2. Attempt to run ./webui.sh

What should have happened?

Web UI should launch and use GPU for acceleration.

What browsers do you use to access the UI ?

Mozilla Firefox

maybe rollback to older version where it still worked

and also check your launch options line 39 and 48

Change your Python version to a supported version 3.10.6 - 3.10.x. Python 3.11.x is not supported

I don't understand why it wouldn't be supported. It's a shame that it isn't.

I had previously used https://archlinux.org/packages/extra/x86_64/python-pytorch/ which has some gpu support included that the pip package has not. I recently tried my luck pulling almost half a year worth of changes and since then it's no longer detecting my GPU. No idea how to proceed from here, and I'm pretty tired of trying random things until it works. I'm surprised that pytorch apparently doesn't even include the rx 6700 xt by default

Edit: Did a full reinstall. Was less painful than I'd expected. Now it works :shrug:

I'm using Python 3.11 and it works fine. Your sysinfo seems to show that you got the wrong torch version. Probably torchvision too. Since you're on Linux and AMD GPU, the version of torch and torchvision should have the +rocm5.4.2 suffix. However sysinfo shows that your torch version is either 2.1.0+cu121 or just 2.1.0. +cu121 is for Nvidia GPUs while no suffix means GPU-less. What you need is to reinstall your torch and torchvision in your venv (i.e. <your webui dir>\venv\scripts\python -m pip install ...) using the following in your pip command: torch==2.0.1+rocm5.4.2 torchvision==0.15.2+rocm5.4.2 --index-url https://download.pytorch.org/whl/rocm5.4.2.

If you understood the above then you can safely upgrade your torch, torchvision, and associated rocm to the latest version. You can get the latest URL for --index-url from https://pytorch.org/get-started/locally/
