[Bug]: AssertionError: Torch not compiled with CUDA enabled

[WhO2022]

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 starting web-ui.bat it shows error:
RuntimeError: Torch is not able to use GPU; add --skip-torch-cuda-test to COMMANDLINE_ARGS variable to disable this check
when adding argument to variable its not generating and shows error:
AssertionError: Torch not compiled with CUDA enabled

Steps to reproduce the problem

1. get runtimeerror above
2. add --skip-torch-cuda-test to COMMANDLINE_ARGS var
3. generate img2img

What should have happened?

work

What browsers do you use to access the UI ?

Mozilla Firefox
