ValueError: _getfinalpathname: embedded null character in path

[Meilaly]

Hello! I ran into a strange problem while doing single image detection:

I searched the Internet for errors and was advised to modify the def win32InstalledFonts(directory=None, fontext='ttf') function in font_manager.py in Anaconda directory.
This is the solution I found on stackflow: http://stackoverflow.com/questions/34004063/error-on-import-matplotlib-pyplot-on-anaconda3-for-windows-10-home-64-bit-pc
But my own font_manager.py does not have the win32InstalledFonts function, I would like to ask you how to solve this problem.

Thanks for reading and I'll appreciate it if you can kindly give some advice .
