[Python] Python OpenCV LBPHFaceRecognizer "Unknown C++ exception from OpenCV code"

Trying to build a mini face recognition project from a set of pictures in a folder

When trying to use LBPH algorithm to do so using:

recognizer = cv.face.LBPHFaceRecognizer()


I get:

"Unknown C++ exception from OpenCV code"
​

If I use:

recognizer = cv.face.LBPHFaceRecognizer_create()
