RuntimeError: One of the differentiated Tensors does not require grad

[void-jw]

I was trying to apply this repo to another SD implementation, basically following here.

However, I am getting the above error msg and I wonder how to fix it.

Thanks in advance!

For SD project, set use_checkpoint as False can solve this issue. It won't affect the performance, but may increase your GPU memory requirement a little bit.
