I am using python and open-CV to do a face matching but there i am getting the following errors?



Module 'cv2' has no 'CascadeClassifier' member
Module 'cv2' has no 'VideoCapture' member
Module 'cv2' has no 'cvtColor' member
Module 'cv2' has no 'COLOR_BGR2GRAY' member
Module 'cv2' has no 'imshow' member
Module 'cv2' has no 'waitKey' member
Module 'cv2' has no 'destroyAllWindows' member



Here is my sample.py



import numpy as np

import cv2



face_cascade = cv2.CascadeClassifier('cascades/data/haarcascade_frontalface_alt2.xml')



cap = cv2.VideoCapture(0)



while(True):

    ret, frame = cap.read()

    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

    faces = face_cascade.detectMultiScale(gray, scaleFactor=1.5, minNeighbors=5)

    for(x,y,w,h) in faces:

        print(x,y,w,h)

    cv2.imshow('frame',frame)

    if cv2.waitKey(20) & 0xFF == ord('q'):

        break





cap.release()

cv2.destroyAllWindows()


How to fixed those errors?






python python-3.x opencv

It should be pip install opencv-python, which is the main opencv. opencv-contrib-python contains contributions of users.
