Opencv图像形状元组拆包

Question

# Importing the libraries
import numpy as np
import cv2


# Load two images
img1 = cv2.imread(r'C:\Users\user1\Pictures\messi.jpg')
img2 = cv2.imread(r'C:\Users\user1\Pictures\opencvimp.jpg')
# I want to put logo on top-left corner, So I create a ROI
rows,cols,channels = img2.shape

以上代码给出了以下错误。

rows,cols,channels = img2.shape
AttributeError: 'NoneType' object has no attribute 'shape

img2.shape我做错了什么？

Answer 1

img2为None。看起来该文件不是有效图像
