AttributeError：模块“cv2.cv2”没有属性“nameWindow”

Question

I've install opencv-python but it still have this problem.

python version:3.7.7

opencv-python version:4.4.0.46

opencv-contrib-python version:4.4.0.46

and here's my code

import cv2 as cv


def GetPicture():
    cv.namedWindow('camera', 1)
    cap = cv.VideoCapture(0)
    ret, frame = cap.read()
    cv.imwrite('C:/person.jpg', frame)
    cap.release()

I've tried different version of opencv, this problem can't be solved.

Answer 1

nameWindow doesn't exist. namedWindow does.

your code as you posted it could not have thrown that error.
