| should only work on Python 3.10+ You can remove the | None, functionally everything will work just as fine. See https://github.com/AUTOMATIC1111/stable-diffusion-webui/pull/4311 on how to fix.

Thats really strange since I have python 3.10.6 installed but only the console from the web ui shows 3.9.5. And it worked until today perfectly fine.

[aliencaocao]

The fact that the console shows 3,9.5 means you are using 3.9.5. You probably didn't activate venv or install it properly, or your PATH is wrongly set.

It works until today because prior to today this block of code does not exist. It was newly committed.

[Ladypoly]

Gosh this is why I hate python so much. I uninstalled every bit of it and restarted, then i installed 3.10.6 fresh and added the PATH correctly. But somehow it still uses 3.9.5 and I have absolutely no Idea where it gets it from.

You need to add a model(sd 1.5 models etc.) to the models section before running this.
