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):File "F:\work\code\python\GFPGAN-master\inference_gfpgan.py", line 9, in <module>from gfpgan import GFPGANerFile "F:\work\code\python\GFPGAN-master\gfpgan\__init__.py", line 2, in <module>from .archs import *File "F:\work\code\python\GFPGAN-master\gfpgan\archs\__init__.py", line 10, in <module>_arch_modules = [importlib.import_module(f'gfpgan.archs.{file_name}') for file_name in arch_filenames]File "F:\work\code\python\GFPGAN-master\gfpgan\archs\__init__.py", line 10, in <listcomp>_arch_modules = [importlib.import_module(f'gfpgan.archs.{file_name}') for file_name in arch_filenames]File "D:\ProgramData\anaconda3\envs\insightface\lib\importlib\__init__.py", line 126, in import_modulereturn _bootstrap._gcd_import(name[level:], package, level)File "F:\work\code\python\GFPGAN-master\gfpgan\archs\arcface_arch.py", line 172, in <module>class ResNetArcFace(nn.Module):File "D:\ProgramData\anaconda3\envs\insightface\lib\site-packages\basicsr\utils\registry.py", line 56, in decoself._do_register(name, func_or_class, suffix)File "D:\ProgramData\anaconda3\envs\insightface\lib\site-packages\basicsr\utils\registry.py", line 42, in _do_registerassert (name not in self._obj_map), (f"An object named '{name}' was already registered "
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
