I stumbled across your 7 years old question while facing the exact same issue. After googling through various pages I finally found the solution that worked for me in the very first attempt, so here's my little solution:

You need to copy the hook files from here and move it to your Pyinstaller site package. That's it.

You can now create your exe and everything should run absolutely fine.

Hopefully, this little solution would be able to provide timely help to someone looking for the light at the end of the tunnel.
