module 'cv2' has no attribute LBPHFaceRecognizer_create()

Time:03-02

I am trying to learn face detection and I got this code from GeeksforGeeks tutorial. However When I run one of the two files, it shows the error AttributeError: module 'cv2' has no attribute 'LBPHFaceRecognizer_create'. I tried uninstalling open cv, installing pip install opencv-contrib-python as well as reinstalling open cv and running it. I am currently running open cv2 4.5.5. The tutorial advised to remove the '.face' from cv2.face.LBPHFaceRecognizer_create() for running cv2, however when I run it with .face, it displays module 'cv2' has no attribute 'face'. Please, someone, help me with this

        subjectpath = os.path.join(datasets, subdir)
        for filename in os.listdir(subjectpath):

            label = id

        prediction = model.predict(face_resize)
        cv2.rectangle(im, (x, y), (x   w, y   h), (0, 255, 0), 3)

I think that you may need to explicitly state "cv2.face" not just "face..."

model = cv2.face.LBPHFaceRecognizer_create()

before doing so...did you confirm that you have a version of Opencv installed that contains the module Face? You can check like this:

import cv2

functions = dir(cv2)
for f in functions:
    print (f)

and if not...install like this:

pip uninstall opencv-contrib-python
pip install opencv-contrib-python

Try this:

face_recognizer = cv2.face_LBPHFaceRecognizer()
model = face_recognizer.create()
