Most things require workarounds, some things aren't possible (or we haven't found workaround yet) and it's not as fast as CUDA. But stable-diffusion inference works, and so does textual inversion training. I was also able to run training of a T5 model with just a couple of tweaks. I'd stick with PyTorch 1.12.1 for now. 1.13 has problems with backpropagation (I get NaN gradients now when I attempt CLIP-guided diffusion -- I think this applies to training too), and some einsum formulations are 50% slower (there is a patch to fix this; I expect it'll be merged soon), making big self-attention matmuls slow and consequently making stable-diffusion inference ~6% slower. |
