Without k-diffusion support, I don't think this replicates Stable Diffusion experience:

Yes, running on M1/M2 (MPS device) was possible with modifications. img2img and inpainting also works.

However you'll run into problems when you want k-diffusion sampling or textual inversion support.

stable-diffusion supports k-diffusion just fine on M1. You just have to detach a tensor in to_d() to stop the values exploding to infinity. https://twitter.com/Birchlabs/status/1563622002581184517?s=2...

I've been following your MPS branch and have run it but couldn't address the issue without this explanation. Thank you!
