Update __init__.py.in

[DrRyanHuang]

When I run:

import dlib

>>> 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'

My __init__.py is as follow:

def add_lib_to_dll_path(path):
    """ On windows you must call os.add_dll_directory() to allow linking to external DLLs.  See
    https://docs.python.org/3.8/whatsnew/3.8.html#bpo-36085-whatsnew.  This function adds the folder
    containing path to the dll search path. 
    """
    try:
        import os
        os.add_dll_directory(os.path.join(os.path.dirname(path), '../../bin'))
        os.add_dll_directory(os.path.join(os.path.dirname(path), '../bin'))
        
    except (AttributeError,KeyError):
        pass
    # except (AttributeError, KeyError, FileNotFoundError):
    #     pass


if 'ON' == 'ON':
    add_lib_to_dll_path('C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.6/lib/cudnn.lib')
    add_lib_to_dll_path('C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.6/lib/x64/cudart.lib')

from _dlib_pybind11 import *
from _dlib_pybind11 import __version__, __time_compiled__

So, to add FileNotFoundError is needed.
