cv2.imshow() is not working properly in PyCharm (MacOS)

Question

Environment:

• interpreter: Python 3.9.0
• OS: macOS Big Sur

This simple code is running fine with no errors; however, no image is produced and nothing is displayed, and I'm forced to manually stop the code and interrupt it to exit, otherwise it just seems to run forever? This exact same code used to work fine on my windows laptop. Any clue? The code:

import cv2

CV_cat = cv2.imread('Cat.jpg')
cv2.imshow('displaymywindows', CV_cat)
cv2.waitKey(1500)

Answer 1

import cv2

CV_cat = cv2.imread('Cat.jpg')
cv2.imshow('displaymywindows', CV_cat)
cv2.waitKey(0)   #wait for a keyboard input
cv2.destroyAllWindows()

try this code

Answer 2

With Ubuntu 18.04 and Anaconda environment I was getting the error with Pycharm as

process finished with exit code 139 (interrupted by signal 11 sigsegv)

Solved it by pip install opencv-python-headless in addition to pip install opencv-python
