我们今天要使用的Wan2.1模型，文生视频与图生视频，效果很不错，我以前的文章部署过comfyUI：

政安晨【零基础玩转各类开源AI项目】基于Ubuntu系统部署ComfyUI：功能最强大、模块化程度最高的Stable Diffusion图形用户界面和后台_comfyui ubuntu-CSDN博客文章浏览阅读1.4k次，点赞10次，收藏25次。ComfyUI这套框架可让您使用基于图形/节点/流程图的界面设计和执行高级稳定扩散管道。_comfyui ubuntuhttps://blog.csdn.net/snowdenkeke/article/details/140156889这次重新部署，完整演绎使用Wan 2.1的模型，看一下在消费级显卡上的使用效果。

当我们完成这次使用演绎后，相信您已经可以掌握一套这是能够商用的视频生成工具了。

下载项目

git clone git@github.com:comfyanonymous/ComfyUI.git

我们可以看到ComfyUI的结构：

至于ComfyUI的特性我这里就不过多赘述了，看我以前的文章。

今天我们就是要把这套彻底用好，用它生成酷炫的视频。。。！！

创建虚拟环境

因为我的AI工具比较多，我都是采用虚拟环境进行安装：

conda create -n comfyui python=3.10.16

创建之后，我们启动它：

conda activate comfyui

真心推荐使用N卡：

pip install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu126

安装完毕，没有报错，如果出现错误，请照此解决：

If you get the "Torch not compiled with CUDA enabled" error, uninstall torch with:pip uninstall torchAnd install it again with the command above.

安装项目依赖

进入刚才下载的项目目录，执行：

pip install -r requirements.txt

尝试运行

基本框架安装完毕后，可以尝试运行一下，熟悉一下界面：

python main.py

本地浏览器打开：http://127.0.0.1:8188

在运行过程中查看服务器打印没有错误，就可以继续了。

此时，您会发现只能本地访问，默认情况下，ComfyUI 可能仅绑定到 127.0.0.1（本地回环地址），导致局域网无法访问。需要将其绑定到 0.0.0.0（监听所有网络接口）。

可以这样配置：
 

方法一：通过启动参数配置

在启动 ComfyUI 时添加 --listen 参数：

python main.py --listen 0.0.0.0 --port 8188

方法二：修改启动脚本

编辑启动脚本，增加如下语句：
 

@echo off
set PYTHONPATH=.
python main.py --listen 0.0.0.0 --port 8188

重新启动，现在您可以局域网中访问啦：

如果提示缺少模型，可以尝试点击下载，测试一下，注意保证网络通畅，嘻嘻。

依次下载模型

1. 下载文本编码器 ：umt5_xxl_fp8_e4m3fn_scaled.safetensors 放入：ComfyUI/models/text_encoders/

放入这个位置： 

2. 下载VAE文件 wan_2.1_vae.safetensors 放入：ComfyUI/models/vae/：

3、下载视频生成模型 【点击下载】

注意：建议使用 fp16 版本而不是 bf16 版本，因为它们会产生更好的结果。

质量等级（从高到低）：fp16 > bf16 > fp8_scaled > fp8_e4m3fn

这些文件位于：ComfyUI/models/diffusion_models/

这些示例使用 16 位文件，但如果内存不足，则可以使用 fp8 文件。

根据您的显存情况进行选择：

4、文字转视频工作流：下载 Json 格式的工作流

工作流文件内容如下:

}

把这个工作流文件拖进comfyUI中：

可以更改提示词：

反向提示词可以不用动，基本一样：

色调艳丽，过曝，静态，细节模糊不清，字幕，风格，作品，画作，画面，静止，整体发灰，最差质量，低质量，JPEG压缩残留，丑陋的，残缺的，多余的手指，画得不好的手部，画得不好的脸部，畸形的，毁容的，形态畸形的肢体，手指融合，静止不动的画面，杂乱的背景，三条腿，背景人很多，倒着走

生成之后的效果如下：

也可以生成动画表情：

我准备使用这张图片生成一段动画：

完成

基于上面地图生视频工作流，生成地动画效果如下：

控制好风格后，应该会不错。

至此，您掌握了一套非凡工具，嘻嘻。
