[Bug]: Torch is not able to use GPU during install

Checklist

• The issue exists after disabling all extensions
• The issue exists on a clean installation of webui
• The issue is caused by an extension, but I believe it is caused by a bug in the webui
• The issue exists in the current version of the webui
• The issue has not been reported before recently
• The issue has been reported before but has not been fixed yet

What happened?

When I installed sd using "Windows (method 1)" (cf. https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/Install-and-Run-on-NVidia-GPUs), processing to "run.bat" step, I encountered this bug. Console log is posted in "Console logs" part (note: all preceeding processes omitted).

Anyway the installation couldn't be continued successfully due to this interruption.

What browsers do you use to access the UI ?

Additional information

According to the guide in https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/Troubleshooting, I could exclude GPU (& drive) issues, so I ran python -m torch.utils.collect_env in console, and the output infos posted in the file below

env.txt

(there is no dir named venv so I just opened the console under root dir D:\soft\sd.webui\webui ).

I think the issue is actually on PyTorch, see "PyTorch version: 2.11.0+cpu" in the file above. Shouldn't it be some like GPU version? Why did run.bat automatically install a cpu-version PyTorch?

[Stulpnagel]

I see the issue. If I take one more "switch-branch-toole.bat" step to switch to dev branch (see guidance) then at the beginning of run.bat process it will install gpu-version Torch for me, otherwise the cpu-version one. But guidance says "switch-branch-toole.bat" setting is just for 50 series GPU. I hold RTX-4060, so I ignored this step before. May be the guidance (or the url point to Torch's installation package) should be updated?

Anyway I can open the webui now. (though I'm not sure switching to dev branch would bring other bugs to me or not)
