序言 步骤 下载comfyUI 配置大模型和vae 下载依赖组件 启动 生成图片 解决办法

序言

由于stable diffusion web ui无法做到对流程进行控制,只是点击个生成按钮后,一切都交给AI来处理。但是用于生产生活是需要精细化对各个流程都要进行控制的。

故也就有个今天的猪脚:Comfyui

步骤

下载comfyui项目 配置大模型和vae 下载依赖组件 启动

下载comfyUI

官网地址:https://github.com/comfyanonymous/ComfyUI

将项目下载到自己喜欢的目录下,下面是我的:

yutao@yutao MINGW64 /e/openai/project
$ git clone https://github.com/comfyanonymous/ComfyUI.git

配置大模型和vae

ComfyUI\models\checkpoints中放大模型文件 在ComfyUI\models\vae中放vae文件。

但是,我们学stable diffusion基本都是从stable diffusion webui开始的,所以我们其实不需要再额外的下载,checkpoint和vae,而是共用他们。

ComfyUI的作者提供了配置方法:

修改extra_model_paths.yaml.example文件重命名为:extra_model_paths.yaml 打开文件,将里面的base_path进行修改:
以下是我的stable-diffusion-webui的路径
a111:
    base_path: E:\openai\project\stable-diffusion-webui

保存退出。

下载依赖组件

在ComfyUI中调出命令行(将文件夹路径上敲cmd,回车即可)中执行:

E:\openai\project\ComfyUI>pip install -r requirements.txt

就会开始下载所需的依赖组件。

启动

命令:python main.py

E:\openai\project\ComfyUI>python main.py

浏览器访问地址:http://127.0.0.1:8188

最左边,因为我之前玩stable diffusion时候已经下载好了guofeng3大模型。所以load checkpoint 里面我显示的是guofeng3.

大模型,我下载的是guofeng3。
放到models/checkpoints文件夹里,例如:E:\openai\project\ComfyUI\models\checkpoints

生成图片

因为默认参数就可以生成一个花瓶,点击右上角的Queue Prompt

但是我的电脑总是不是那么顺利。

详细描述文章:【ComfyUI】RuntimeError: CUDA error: operation not supported

报了如下错误:

RuntimeError: CUDA error: operation not supported
CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1.
Compile with `TORCH_USE_CUDA_DSA` to enable device-side assertions.

其实就是说,我当前电脑的GPU或硬件,并不支持当前CUDA中的某些操作。

解决办法

官方提供了两种解决策略。

方式一:黑名单策略

加完后,再重启。发现还是不行。

方式二:启动时添加–disable-cuda-malloc

# 注意--disable-cuda-malloc
E:\openai\project\ComfyUI>python main.py --disable-cuda-malloc

最后,通过方式二,得以解决。
