cv2.imshow() function is opening a window that always says not responding - python opencv

Question

I am trying to run a very simple program. To open and jpg file and display it using the opencv library for python. Initially it all worked fine but now it just opens a windo

Answer 1

I did also face the same issue. I am running through command line python prompt in centos 7 with the following code

>> import cv2, numpy as np
>> cap=cv2.VideoCapture(0)
>> img=cap.read()
>> cap.release()
>> cv2.imshow('image',img[1])
>> cv2.waitKey(0)
>> cv2.destroyAllWindows()
>> cv2.waitKey(1)

Even then the problem persisted and didn't solve. So I added

>> cv2.imshow('image',img[1])

Adding this did close the image window.Running the command again would create a new instance. Hope you can try if you still face any issues.
