In opencv-python tutorials core operations basic operations on images accessing pixel value throws an error

Here is the code(with error as i am working directly on the shell as instructed by the website) same as on the website:

import cv2 import numpy as np img = cv2.imread('result.jpg') px = img[100,100]

Traceback (most recent call last): File "<pyshell#3>", line 1, in <module> px = img[100,100] TypeError: 'NoneType' object has no attribute '__getitem__'

Thanks :)
