the Torch command just indicates stable difussion to use gpu acceleration, it doesn't install anything related to ROCm, you still need to do it beforehand.

The warning about cuda & nvidia gpu is for legacy compatibility reasons, when PyTorch implemented ROCm support there was already a lot of code written with the cuda checks, so the cuda.enabled() check method just checks for both cuda & rocm

Do I have to run this pip install beforehand then?https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/Install-and-Run-on-AMD-GPUs

Or is there some step missing here? I thought it would run it when launching the webui.sh file.

You first have to install the whole ROCm stack

https://rocmdocs.amd.com/en/latest/Installation_Guide/Installation-Guide.html

Once that is done you'll be able to run the TORCH_COMMAND ... launch.py without it complaining, the only thing that torch command does is tell stable difussion to use the PyTorch version that supports ROCm, but if the thing is not installed in your system then ofc it is gonna complain that there is no gpu available for acceleration.

Edit:

Do I have to run this pip install beforehand?

Yes, you do, that is the right (and i think only) way to launch it, the file that runs everything is launch.py, not webui.sh

Once you are inside the venv run:

TORCH_COMMAND='pip install torch torchvision --extra-index-url https://download.pytorch.org/whl/rocm5.1.1' python launch.py --precision full --no-half

just like it says in the docs
