Please resolve this issue:

import numpy as np
import matplotlib.pyplot as plt
import cv2
im1 = cv2.imread('C://Test-C//33319//33319_2ms.jpg');
cv2.imshow('image', im1 );
cv2.waitKey(0)

It can't open the image correctly. Check if the path is correct and the file exist. The error is very easy to be understood: (-215:Assertion failed) size.width>0 && size.height>0 in function 'cv::imshow basically the function that have to show to you the image (imshow) throw an error because the size of the image is not positive, it means that the reading operation have failed.

No known OS uses double forward slashes as path separator.
