ComfyUI 是功能强大且高度模块化的 AI 绘画工具，基于 Stable Diffusion 技术，采用节点式工作流界面，使用户能够更直观地控制图像生成过程。特点是模块化设计，允许用户通过拖放节点来创建和调整工作流，极大地提高了灵活性和可定制性。速度更快，灵活的组建工作流，专业团队的需求，节点式编辑。
GitHub: https://github.com/comfyanonymous/ComfyUI
git clone https://github.com/comfyanonymous/ComfyUI
配置 conda 环境
conda create -n comfyui python=3.9
pip install torch==1.13.1+cu117 torchvision==0.14.1+cu117 torchaudio==0.13.1 --extra-index-url https://download.pytorch.org/whl/cu117
pip install numpy==1.26.4
Numpy 必须是 1.x 版本，否则报错：
A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.0.1 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
安装其他库：
pip install -r requirements.txt
启动任务，默认端口是 8188：
python3 main.py --listen 0.0.0.0
# nohup python3 -u main.py --listen 0.0.0.0 > nohup.run_main.out &
# ps -aux | grep "main.py"
# kill -9 [pid]
启动成功的日志，例如 http://[your ip]:8188/：

ComfyUI 启动成功：
ComfyUI 支持复用 Stable Diffusion WebUI 的配置，修改 extra_model_paths.yaml：
a111:
base_path: workspace/stable_diffusion_webui/
checkpoints: models/Stable-diffusion
configs: models/Stable-diffusion
vae: models/VAE
loras: |
models/Lora
models/LyCORIS
upscale_models: |
models/ESRGAN
models/RealESRGAN
models/SwinIR
embeddings: embeddings
hypernetworks: models/hypernetworks
controlnet: extensions/sd-webui-controlnet/models
注意：需要修改 controlnet 的默认模型路径，这个部分与默认不一致，其他逐个验证即可。
在 workspace_comfyui/ComfyUI/custom_nodes 文件夹中，安装自定义 ComfyUI-Manager 插件：
第 1 次启动时，需要等待安装配置，## ComfyUI-Manager: installing dependencies. (GitPython)
安装翻译插件：AIGODLIKE-ComfyUI-Translation，重启服务即可：
cd custom_nodes
git clone https://github.com/AIGODLIKE/AIGODLIKE-ComfyUI-Translation.git
将 ComfyUI 页面翻译成中文：
点击 Queue Prompt，即可运行程序。
提示词：
beautiful scenery nature glass bottle landscape, purple galaxy bottle, 美丽的风景自然玻璃瓶景观，紫色银河瓶。如图所示：
运行报错：
File "workspace_comfyui/ComfyUI/custom_nodes/ComfyUI-Manager/glob/manager_server.py", line 1710, in <lambda>
threading.Thread(target=lambda: asyncio.run(default_cache_update())).start()

self._continue = None
File "aiohttp/helpers.py", line 713, in __exit__
raise asyncio.TimeoutError from None
asyncio.exceptions.TimeoutError
原因是 GitHub 国内访问异常，使用代理即可，参考源码 ComfyUI-Manager/glob/manager_server.py#1688，即：
async def default_cache_update():
async def get_cache(filename):
# uri = 'https://raw.githubusercontent.com/ltdrdata/ComfyUI-Manager/main/' + filename
uri = 'https://mirror.ghproxy.com/https://raw.githubusercontent.com/ltdrdata/ComfyUI-Manager/main/' + filename
cache_uri = str(core.simple_hash(uri)) + '_' + filename
cache_uri = os.path.join(core.cache_dir, cache_uri)
json_obj = await core.get_data(uri, True)
with core.cache_lock:
with open(cache_uri, "w", encoding='utf-8') as file:
json.dump(json_obj, file, indent=4, sort_keys=True)
print(f"[ComfyUI-Manager] default cache updated: {uri}")
a = get_cache("custom-node-list.json")
b = get_cache("extension-node-map.json")
c = get_cache("model-list.json")
d = get_cache("alter-list.json")
e = get_cache("github-stats.json")
await asyncio.gather(a, b, c, d, e)
threading.Thread(target=lambda: asyncio.run(default_cache_update())).start()
修改 uri，增加 https://mirror.ghproxy.com/ 前缀，即可
