FutureWarning: You are loading the variant fp16 from microsoft/vq-diffusion-ithq via revision='fp16'. This behavior is deprecated and will be removed in diffusers v1. One should use variant='fp16' instead. However, it appears that microsoft/vq-diffusion-ithq currently does not have the required variant filenames in the 'main' branch.
The Diffusers team and community would be very grateful if you could open an issue: https://github.com/huggingface/diffusers/issues/new with the title 'microsoft/vq-diffusion-ithq is missing fp16 files' so that the correct variant file can be added.
