视频生成模型 Zeroscope_v2_576w 开源 - 腾讯云开发者社区-腾讯云

生成视频代码：

import torch
from diffusers import DiffusionPipeline, DPMSolverMultistepScheduler
from diffusers.utils import export_to_video
import os
# os.environ['HTTP_PROXY'] = 'http://127.0.0.1:7890'os.environ["HF_TOKEN"] = "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"
# os.environ['HTTPS_PROXY'] = 'https://127.0.0.1:7890'# pipe = DiffusionPipeline.from_pretrained(r"D:\360安全浏览器下载", torch_dtype=torch.float16)
pipe = DiffusionPipeline.from_pretrained("cerspense/zeroscope_v2_576w", torch_dtype=torch.float16,use_auth_token=os.environ["HF_TOKEN"])
pipe.scheduler = DPMSolverMultistepScheduler.from_config(pipe.scheduler.config)
pipe.enable_model_cpu_offload()prompt = "Darth Vader is surfing on waves"
video_frames = pipe(prompt, num_inference_steps=40, height=320, width=576, num_frames=24).frames
video_path = export_to_video(video_frames)
print(video_path)

维度报错：

ValueError: too many values to unpack (expected 3)

解决方法，修改代码：
