Hello, I've checked my execute command and config file, which is the same as yours, but still can't solve this problem. Could you give any more solutions？

hi，Give me your error information which is showed in terminal.

[ray-lee-94]

I meet the problem since in the main.py, the try: except catch nothing. You should remove the try except first to find the error

[cs-mshah]

Facing the same issue for the cin-ldm-vq-f8.yaml config.

It might be an issue with this code needing an older pytorch_lightning version. Try installing version 1.6.1 (this may create other problems but should solve this.
