Thank you for the contribution @chaowenguo! I've added instruct-pix2pix to single_file_utils to complete from_single_file support.

Example

from diffusers import StableDiffusionInstructPix2PixPipeline

pipe = StableDiffusionInstructPix2PixPipeline.from_single_file("https://huggingface.co/timbrooks/instruct-pix2pix/blob/main/instruct-pix2pix-00-22000.safetensors")

cc @yiyixuxu We've had a few PRs for pytorch_xla support recently, should we create an issue to track pipelines missing pytorch_xla support and open it to the community? Edit: Created #10357
