[Bug]: Webui doesn't start

[NotSoCommonSense]

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?

Webui doesn't start.

Happens even on fresh install. I'm using directml. I've tried adding --skip-torch-cuda-test to webui-user.bat to no avail.

My older installation (~April 2023) worked fine but some extensions I wanted to use supposedly needed a newer version of the webui.

Steps to reproduce the problem

1. Start webui.
2. ???

What should have happened?

WebUI should have started.

What browsers do you use to access the UI ?

Microsoft Edge

Additional information

I'm kind of dumb as a rock when it comes to this stuff, so please try to explain it very simply if possible and elaborate, thank you

Never mind, tried adding --skip-torch-cuda-test again and it worked. Flabbergasted.

Right click webui-user.bat, click edit, then add --skip-torch-cuda-test after COMMANDLINE_ARGS=

However that does force SD to use the CPU making generation extremely slow. This worked for me to make it use the GPU again: https://www.reddit.com/r/StableDiffusion/comments/18vmkon/comment/khpbnvo/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

i spoke to soon :( when i tried to generate the image it wouldnt and now after changing the args it says this: launch.py: error: unrecognized arguments: --use-directml

[Miisa1]

once i removed --use-directml i get this prompted: Stable diffusion model failed to load
