ReShapping error while using open cv in python

[barry76]

Using mentioned below code I am trying to reshape the image and use it on a specific row and column parameters

import cv2 import numpy as np #shapes of both the image has to same img1 = cv2.imread('3DScatter.png') img2 = cv2.imread('python2.png') # I want to put logo on top-left corner, So I create a ROI rows,cols,channels = img2.shape roi = img1[0:rows, 0:cols ] # Now create a mask of logo and create its inverse mask img2gray = cv2.cvtColor(img2,cv2.COLOR_BGR2GRAY) cv2.imshow('mask', mask) cv2.waitKey(0) cv2.destroyAllWindows()

but while using this co facing the error due to which I am not able to reshape the image

Traceback (most recent call last): File "C:/Users/Misha/Desktop/test/CV/ImageArithmatics and Logics.py", line 29, in <module> rows,cols,channels = img2.shape AttributeError: 'NoneType' object has no attribute 'shape'

Any advice on this will be really help
