[Bug]: Torch is not able to use GPU; add --skip-torch-cuda-test to COMMANDLINE_ARGS variable to disable this check

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?

The error message is not intuitive. It's a batch file, not an executable. I am a developer but not versed in anything being used. I had the impression that Automatic1111 would just work. Here is the dump for AMD 3800 / 32GB / RX 6800 / 10 x64 22H2:

Steps to reproduce the problem

Open webui-user.bat

What should have happened?

The program should make an attempt to not bomb out on this error or at least provide a useful and up-to-date debugging suggestion.

What browsers do you use to access the UI ?

AMD + Windows not supported, only on linux
please read the installation instructions
https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/Install-and-Run-on-AMD-GPUs

Windows+AMD support has not officially been made for webui,
but you can install lshqqytiger's fork of webui that uses Direct-ml. https://github.com/lshqqytiger/stable-diffusion-webui-amdgpu

[jabcreations]

AMD GPUs are listed, then the index page should probably be updated to say "AMD on Linux only" or you'll just keep getting lot of disappointed people posting bugs.

On the upside thank you for the fork recommendation.

the funny thing is this thing is so broken nothing works anymore im on a RTX 2060 same error nothing i try fixes it he really needs to do a full code rewrite but seeing as there has been no activity at months I highly doubt that's going to be the case

Windows 10
Cuda 11.8 even tried it with Cuda 12.6 and 12.8
RTX 2060 12 GB my gpu has been fine with this before
32GB of ram

I've done hundreds of clean installs same error
it wont even load lol this thing a completely dead and garbage project

I got similar error on windows + rtx3060 several days ago, the problem was in the python version missmatch. (warning appears if this is the case)

After downgrading python works just fine

Anyway, I moved to ComfyUI shortly after

[HexRift]

i have been using the same Python version "3.10.6" as what was always in the docs

[HexRift]

the other problem is I primarily use it to train models and I haven't found anything else that will allow me
