See #4332.

After diffusers 0.17.0, non-reentrant variant of torch.utils.checkpoint.checkpoint becomes default but is incompatible with Deepspeed Stage3.

I found #4118, then replaced torch.utils.checkpoint.checkpoint with deepspeed.checkpointing.non_reentrant_checkpoint before import diffusers but still met an error said "RuntimeError: The size of tensor a (0) must match the size of tensor b (1280) at non-singleton dimension 1".

Maybe I use non_reentrant_checkpoint improperly. Any suggestions for me to make non-reentrant checkpoint compatible with stage3?

I met the same error. Does anybody have a solution?
