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
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
Traceback (most recent call last):

AssertionError: An object named 'ResNetArcFace' was already registered in 'arch' registry!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
ResNetArc2Face
如下替换掉
然后源代码重新安装，执行解决此问题
python setup.py develop
