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

This code works for me from IDLE:

# -*- coding: utf-8 -*-

import numpy as np
import cv2

# Load an color image in grayscale
img = cv2.imread('Lena.tiff',0)
WINDOW_NAME = 'Image de Lena'
cv2.namedWindow(WINDOW_NAME, cv2.CV_WINDOW_AUTOSIZE)
cv2.startWindowThread()

# Display an image
cv2.imshow(WINDOW_NAME,img)
cv2.waitKey(0) 


cv2.destroyAllWindows()

Hope this helps for future readers.
