本文记录了在Ubuntu系统中安装ComfyUI的详细步骤，包括从Git仓下载，设置Python 3.9和Torch环境，安装依赖，启动参数说明，以及遇到的ModuleNotFoundError: No module named ‘chardet’、xFormers加载C++/CUDA扩展失败和Aborted错误的解决方案。确保在Win浏览器和本地局域网中可以访问。

1 安装

1.1 Git仓下载ComfyUI

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

$ cd ~
$ git clone https://github.com/comfyanonymous/ComfyUI

$ cd ComfyUI

1.2 安装环境

1.2.1 Python 版本

ComfyUI在Ubuntu环境下，python 3.8、 3.9、 3.10 实测都能通过
使用3.9是为了后续兼容其他第三方插件，有些插件在3.10下依赖版本冲突
conda create -n comfyui python==3.9
conda activate comfyui

1.2.2 Torch 版本

Conda 安装
conda install pytorch torchvision torchaudio pytorch-cuda=12.1 -c pytorch -c nvidia
Pip 安装
pip install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu121

二选一即可

$ conda install pytorch torchvision torchaudio pytorch-cuda=12.1 -c pytorch -c nvidia
