Running the colab notebook fast-DreamBooth.ipynb. Training seems to complete fine, but running the UI produces:

Traceback (most recent call last):

Just tried with https://colab.research.google.com/github/TheLastBen/fast-stable-diffusion/blob/main/fast_stable_diffusion_AUTOMATIC1111.ipynb#scrollTo=PjzwxTkPSPHf and got the same error

try test running the notebook without the first cell

Had the same issue

Fix:

1. Rename /content/gdrive/MyDrive/sd/stable-diffusion-webui to /content/gdrive/MyDrive/sd/stable-diffusion-webui-old.
2. Reinstall dependencies.
3. New ...webui folder will be fixed and working.

This is annoying, I have to reinstall all the extensions

Yes. How we deal with it @TheLastBen? I guess all extension not work properly when we have to relaunch again?

[TheLastBen]

Rename the current SD folder, then copy the extension back to the new SD folder

Following the comment by @danielgwilson fixed my issue. Thanks all!
