What diffusion models does it support?

@nateraw Code:

from stable_diffusion_videos import StableDiffusionWalkPipeline
import torch

pipeline = StableDiffusionWalkPipeline.from_pretrained(
    "prompthero/openjourney-v4",
    torch_dtype=torch.float16,
    revision="fp16",
).to("cuda")

video_path = pipeline.walk(
    prompts=['a cat', 'a dog'],
    seeds=[42, 1337],
    num_interpolation_steps=20,
    height=512,  # use multiples of 64 if > 512. Multiples of 8 if < 512.
    width=512,   # use multiples of 64 if > 512. Multiples of 8 if < 512.
    output_dir='dreams',        # Where images/videos will be saved
    name='animals_test',        # Subdirectory of output_dir where images/videos will be saved
    guidance_scale=7.5,         # Higher adheres to prompt more, lower lets model take the wheel
    num_inference_steps=50,     # Number of diffusion steps per image generated. 50 is good default
)

Error Message:

OSError: fp16 is not a valid git identifier (branch name, tag name or commit id) that exists for this model name. Check the model page at 'https://huggingface.co/prompthero/openjourney-v4' for available revisions.
