RuntimeError: Unable to open assets\shape_predictor_68_face_landmarks.dat**

I don't know if this is macos specific issue or not.
While I tried to run PyFry.py, dlib is not able to open "shape_predictor_68_face_landmarks.dat" which is under assets folder.

Start with PyFry.py at addFlare on line 54, where the assets\shape_predictor_68_face_landmarks.dat path is passed to dlib, and verify the referenced file under assets. Run python PyFry.py on macOS to reproduce the error. Done means the predictor opens successfully and execution proceeds without the RuntimeError.
