conda环境下RuntimeError: Couldn‘t determine Stable Diffusion‘s hash问题解决

1 问题描述

在部署stable-diffusion-webui项目时，出现RuntimeError: Couldn't determine Stable Diffusion's hash错误，错误信息如下：

 [root@localhost stable-diffusion-webui]# sh webui.sh

2 解决方法

（1）查看git版本

[root@localhost stable-diffusion-webui]# git --version
git version 1.8.3.1

如果当前版本为1.8，先要将git升级到最新版本，升级命令如下：

把老版本的 Git 卸掉。
sudo yum -y remove git
sudo yum -y remove git-*


添加 End Point 到 CentOS 7 仓库
sudo yum -y install https://packages.endpointdev.com/rhel/7/os/x86_64/endpoint-repo.x86_64.rpm


安装 Git
sudo yum -y install git

 完成后查看git版本

[root@localhost ~]# git --version
git version 2.41.0

 （2）依次忽略相关文件夹

由于git安全机制问题，导致项目读取不到相应的stable-diffusion-stability-ai等插件。通过如下命令解决：

git config --global --add safe.directory /opt/stable-diffusion-webui/repositories/stable-diffusion-stability-ai
 
git config --global --add safe.directory /opt/stable-diffusion-webui/repositories/CodeFormer
 
git config --global --add safe.directory /opt/stable-diffusion-webui/repositories/k-diffusion
 
git config --global --add safe.directory /opt/stable-diffusion-webui/repositories/BLIP
 
git config --global --add safe.directory /opt/stable-diffusion-webui/repositories/taming-transformers

至此，问题已经解决
