@cmeth990 - Can you share more of the traceback, and the specific settings of your txt2img and img2img?

I'm done

Keep the model folder and delete all

Reinstall according to the previous manual installation method

Select Skip when downloading the model, then copy the model folder back and continue the installation until it is completed

@MirYin This resolved it for you?

[MirYin]

@MirYin这给你解决了吗？

yes

I solved the problem. I deleted all the files and reinstalled them according to the manual installation mode

The prerequisite is to set the version of python at 3.9.6 or 3.10.9

This happens to me when face restoration is on. Either gfpgan or codeformer. I have a fresh installation of the latest version of invoke ai.

Same thing happens with gfpgan except this line is slightly different:

image = self.gfpgan.process( AttributeError: 'NoneType' object has no attribute 'process'

For anyone looking to solve this issue, check that your gfpgan and codeformer models are in the expected directory. This error is thrown when the models cannot be found. Missing models are logged upon startup.
