刚才第一次碰了一下这个美颜算法，要用dlib，dlib 还挺折腾人啊

除了C++环境，还得安装 cmake 和 boosting(好像是这个来着)

最后编译也要了好几分钟hhh

问题如下：

运行

>>> import dlib

Traceback (most recent call last):

  File "xxxxx.py", line 1, in <module>
    import dlib

  File "xxxxx\lib\site-packages\dlib\__init__.py", line 21, in <module>
    add_lib_to_dll_path('C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.6/lib/cudnn.lib')

  File "xxxxx\lib\site-packages\dlib\__init__.py", line 11, in add_lib_to_dll_path
    os.add_dll_directory(os.path.join(os.path.dirname(path), '../../bin'))

  File "xxxxx\lib\os.py", line 1109, in add_dll_directory
    cookie = nt._add_dll_directory(path)

FileNotFoundError: [WinError 2] The system cannot find the file specified : 'C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.6/lib\\../../bin'
FileNotFoundError: [WinError 2] 系统找不到指定的文件。 : 'C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.6/lib\\../../bin'

查看那个报错文件：

把那个文件改一下：

except (AttributeError,KeyError):
    pass

改成：

except (AttributeError, KeyError, FileNotFoundError):
    pass

加个FileNotFoundError就OK了

已经再github上留下了issue
