How to use lightx2v/Wan2.2-NVFP4-Sparse with Diffusers:
pip install -U diffusers transformers accelerate
import torch from diffusers import DiffusionPipeline # switch to "mps" for apple devices pipe = DiffusionPipeline.from_pretrained("lightx2v/Wan2.2-NVFP4-Sparse", dtype=torch.bfloat16, device_map="cuda") prompt = "Astronaut in a jungle, cold color palette, muted colors, detailed, 8k" image = pipe(prompt).images[0]
I'm new to it and I don't see a way to use a custom model other than selecting from predefined list, and the list only has nf4 versions of wan2.1 small models.
