Hi, really nice and thank you for your work. Currently diffusers doesn't have einops as a dependency. Is it possible that you refactor all the rearrange calls to just use a torch equivalent without the need of external libraries?

Okay, I will make the necessary modifications. Additionally, I noticed that the call method is not functioning properly in the documentation. Could you please help check the cause?

Thanks for working on this. I just added few minor comments.

I am unsure about self.denoise(). On one hand I see its value but since it deviates from our usual pipeline implementations, I will defer the decision to the other reviewers.
