response from the image window to kernel is not getting passed

here is a simple part of code … to display a image and then closing it off on pressing the esc or ‘q’

import cv2
img=cv2.imread('/<imagelocation>')
cv2.imshow('image',img)
k=cv2/waitKey(0)
if k == 27 or ord('q'):
     cv2.destroyAllWindows()

now the image is shown properly but on pressing ‘q’ or esc , it hangs and then you have to force quit the image , and immediately notebook detects this failure and restart the kernel

Pardon me for the blank error messages in the previous post First Error: Hello World: Fatal IO error 11 (Resource temporarily unavailable) on X server :0

Second error: Hello World: Fatal IO error 11 (Resource temporarily unavailable) on X server :0

Just don’t write your message on the first line after the triple quote, it is ment for the language highlighting
