Stable Diffusion 使用安装

news2024/11/16 1:23:25

Stable Diffusion是一个文本到图像的潜在扩散模型，由CompVis、Stability AI和LAION的研究人员和工程师创建。它使用来自LAION-5B数据库子集的512x512图像进行训练。使用这个模型，可以生成包括人脸在内的任何图像，因为有开源的预训练模型，所以我们也可以在自己的机器上运行它。

一、本地安装

Tip: Python 版本为 3.10.6

 git clone https://github.com/AUTOMATIC1111/stable-diffusion-webui.git
 
 cd stable-diffusion-webui/
 
 # 请切换Python venv, 魔法上网, 下载时间比较长
 git config --global http.proxy http://127.0.0.1:10887
 pip install --upgrade pip
 export http_proxy=http://127.0.0.1:10887;export https_proxy=http://127.0.0.1:10887;
 sh ./webui.sh

二、安装报错汇总

2.1 安装gfpgan报错

解决方案:

 git config --global http.proxy http://127.0.0.1:10887

2.2 未下载模型导致服务无法运行

 No checkpoints found. When searching for checkpoints, looked at:
  - file /Users/liuli/Devspace/chatgpt/stable-diffusion-webui/model.ckpt
  - directory /Users/liuli/Devspace/chatgpt/stable-diffusion-webui/models/Stable-diffusion
 Can't run without a checkpoint. Find and place a .ckpt or .safetensors file into any of those locations. The program will exit.

解决方案:

下载模型, 并将下载的模型放到 stable-diffusion-webui/models/Stable-diffusion 目录中。
