Python OpenCV - waitKey(0) does not respond?

Question

I\'m using opencv 2.4.7 on ubuntu 12.04. I\'m programming with python and I have a problem when i run this script:

import cv2

img = cv2.imread(\'34762092361         


        

Answer 1

There is a problem with unix based system running opencv programs from python notebooks.

Check this alternate method My suggestion is to run code in python in terminal. You will not face any kind of problem

Copy the same code and save with filename.py

import cv2
input = cv2.imread('path_to_image.png')
cv2.imshow('Hello World', input)
cv2.waitKey(0)
cv2.destroyAllWindows()

then open specific directory and then open terminal

Steps:

Open Terminal
cd path/to/filename.py
source activate YOURPROFILE 
python filename.py

This will solve problem
