AttributeError: module diffusers has no attribute LCMScheduler

[slashdottir]

This was working great a week or two ago, then I ran it today, same env, no changes or updates, suddenly it has an error?

I'm not sure how that's possible
Thank you for any clues

You need the current version of main.py, as well as requirements.txt (which results in an updated diffusers).

So do a git pull, make sure you're within the correct virtual environment (if you're not, do a source venv/bin/activate), and run pip install -r requirements.txt

Those are the steps I took to get myself running again.

Update your diffusers to lastest version. like:
pip install diffusers==0.23.1

This is still affecting new installs, really should be rolled into the one-click install process.

by me is

AttributeError: module 'diffusers.schedulers' has no attribute 'scheduling_lcm'. Did you mean: 'scheduling_ddim'?

anyone help?
