Python-OpenCv错误261

Question

I'm new to Python-OvenCV programming. I'm using python idle to load and display image from folder. its showing the following error:

**Traceback (most recent call last):   
File "C:\Python27\a.py", line 4, in <module>


cv2.imshow("abc",img)    
error: ..\..\..\..\opencv\modules\highgui\src\window.cpp:261: error: (-215)   size.width>0 && size.height>0 in function cv::imshow**    

my code is:

import cv2    
import numpy as np    
img = cv2.imread("C:\Users\Mayur\Desktop\ab.bmp",0)    
cv2.imshow("abc",img)     
cv2.waitKey()    

I have searched for solutions but they are all for matlab and I'm using python IDLE.

Answer 1

You may have found the solution already, but ill give an answer anyways.

This is a common mistake when trying to read files in python. in my experience python does not like the "\\" when you are naming the file location. instead you should use a "/". Here is what is should look like:

img = cv2.imread("C:/Users/Mayur/Desktop/ab.bmp",0)
