Why doesn't OpenCV+Python work?

Question

Python

After much torment and dancing with a tambourine, I installed OpenCV. But the above code refuses to work: the window that I create appears and freezes...

import cv2

image = cv2.imread("plan.png")

cv2.namedWindow("main", cv2.WINDOW_AUTOSIZE)

cv2.imshow("main", image)

Answer 1

Try like this:

import cv2
image = cv2.imread("plan.png")
cv2.namedWindow("main", cv2.WINDOW_AUTOSIZE)
while(1):
    cv2.imshow("main", image)
    k = cv2.waitKey(1) & 0xFF
    if k == 27:
        break

Exit - by pressing the "Esc" key
