问题An object named ‘ResNetArcFace‘ was already registered in ‘arch‘ registry!

在安装 GFPGAN 的时候，一切都顺利，但是执行的时候出现了错误，哦还有一个问题，

问题一

就是如果basicsr安装不成功可以执行如下命令

复制代码

pip install -i https://mirrors.aliyun.com/pypi/simple tb-nightly
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple basicsr==1.4.2

问题二

回归上面的问题，如果执行出现了如下错误

复制代码

问题原因

发现是由于ResNetArcFace已经被注册，搜索了下，发下我安装的另外一个库已经包含了

问题解决方案

那咋办了

方法一

一个是重新开个环境，通过conda创建一个虚拟环境，排除环境依赖，也就不存在重复使用问题

conda create --name xxx python=3.11

方法二

一个是修改源码

复制代码

ResNetArc2Face

如下替换掉

然后源代码重新安装，执行解决此问题

复制代码

python setup.py develop
