Diffusers How to use lightx2v/Wan2.1-T2V-1.3B-longcat-step1500 with Diffusers:
pip install -U diffusers transformers accelerate
import torch
from diffusers import DiffusionPipeline
from diffusers.utils import export_to_video
# switch to "mps" for apple devices
pipe = DiffusionPipeline.from_pretrained("Wan-AI/Wan2.1-T2V-1.3B-Diffusers", dtype=torch.bfloat16, device_map="cuda")
pipe.load_lora_weights("lightx2v/Wan2.1-T2V-1.3B-longcat-step1500")
prompt = "A man with short gray hair plays a red electric guitar."
output = pipe(prompt=prompt).frames[0]
export_to_video(output, "output.mp4")
