前言

Wan2.1，是阿里云开源的一款AI视频生成大模型，支持文生视频和图生视频任务，具备强大的视觉生成能力。无论是复杂的运动生成，还是物理规律的精准模拟，Wan2.1都能轻松应对。
14B参数的专业版Wan2.1模型在Vbench评测中以86.22%的成绩超越Sora、Luma等国内外模型，稳居榜首。1.3B参数的极速版则能在消费级显卡上运行，显存需求低，适合二次开发和学术研究

---

一、平台环境准备

镜像选择：pytorch:v24.10-torch2.4.0-torchmlu1.23.1-ubuntu22.04-py310
【请注意仔细查看自己的镜像版本，老版本改法，请查阅之前文章】

卡选择：任意一款MLU3系列及以上卡

二、环境配置

1.comfyui安装

私信获取 comfyui-v0.6.0.tar.gz 插件版

git clone -bv0.3.27 https://githubfast.com/comfyanonymous/ComfyUI.git #直接下载官方的diffusers
tar -zxvf comfyui-v0.6.0.tar.gz
git apply comfyui_0.3.27_mlu0.6.0.patch
pip install -r requirements.txt #至此环境安装完成

三、模型下载

git-lfs clone https://hf-mirror.com/Comfy-Org/Wan_2.1_ComfyUI_repackaged
#这个下载很久请科学上网，或者从魔搭找相应模型
将下图中的所split_files的模型放置与comfyui代码中的指定位置
ComfyUI/models/clip_vision
ComfyUI/models/diffusion_models
ComfyUI/models/text_encoders
ComfyUI/models/vae

四、工作流导入

}

导入以上json工作流之后

五、开始运行

python main.py --listen --port 8998 --force-fp16 --tmo --fp16-vae #打开服务后
浏览器 http://0.0.0.0:8998
--tmo就可以用到mlu 不加则可以则是英伟达的用法
