When I am trying to use Colab for stable diffusion ,
I met error below today :
ImportError cannot import name 'rank_zero_only' from 'pytorch_lightning.utilities.distributed'
After searching , I got the answer finally from here.
Changed From : from pytorch_lightning.utilities.distributed import rank_zero_only
To : from pytorch_lightning.utilities.rank_zero import rank_zero_only
Before Run , remember to downgrade !pip install pydantic==1.10.11
So I updated the line 20 in file ddpm.py as indicated in debug log, and the issue is resolved.
