Why does DDPMPipeline.from_pretrained() fail to execute, while passing the same parameters to UNet2DModel.from_pretrained() works fine?

Whether it’s a bug or intended behavior, when loading models from the pipeline class, adding use_safetensors=True sometimes causes problems. The reason this doesn’t happen with Unet2DModel is that the search range for files is slightly narrower.

You can simply delete use_safetensors=True, but updating Diffusers and related libraries to the latest versions may also resolve the issue.

pip install -U diffusers huggingface_hub[hf_xet]
