"RuntimeError: Input type (c10::Half) and bias type (float) should be the same" when running examples/make_music_video.py #150

When trying to generate a music video using examples/make_music_video.py locally, I get the following error:

RuntimeError: Input type (c10::Half) and bias type (float) should be the same

However when using the snippet in README.md everything works well.

Atomic-Germ commented 1 year ago

Can you give a description of your environment? Python version, OS and version, etc.

philgzl commented 1 year ago

Python: 3.10.7 OS: Scientific Linux 7.9 (Nitrogen)

It seems like what is causing the issue is setting vae=AutoencoderKL.from_pretrained(f"stabilityai/sd-vae-ft-ema") when initializing the StableDiffusionWalkPipeline here. This is not done in the code snippet in README.md, and commenting this line out fixes the issue.

Maybe the script should be updated to also use SD 2.1. Maybe I open a PR.

lingster commented 1 year ago

alternatively you could resolve using this:

        revision = "fp16"
        model_path = "runwayml/stable-diffusion-v1-5"

# add this into your StableDiffusionWalkPipeline(): 

        vae=AutoencoderKL.from_pretrained(
            model_path,
            subfolder="vae",
            revision=revision,
            torch_dtype=torch_dtype
        ),
