Python3 Opencv error with Hconcat and Vconcat-CodePudding

So i was trying out the vconcat and hconcat funktion of OpenCv2 but whenever i run it, it gives me this error. cv2.error: OpenCV(4.6.0) /io/opencv/modules/core/src/matrix_operations.cpp:65: error: (-215:Assertion failed) src[i].dims <= 2 && src[i].rows == src[0].rows && src[i].type() == src[0].type() in function 'hconcat

here is the code:

import cv2

img1 = cv2.imread('test1.jpeg')
img2 = cv2.imread('book.jpg')

h_concat_img = cv2.hconcat([img1, img2])
v_concat_img = cv2.vconcat([img1, img2])

cv2.imshow('horizontal', h_concat_img)
cv2.imshow('vertical', v_concat_img)

cv2.waitKey(0)
cv2.destroyAllWindows()

And i think its only a problem from my site.

Python 3.10.8 Opencv 4.6.0

I was very confused even tried copying "Exactly" what a website told me with the same file name, here is the code

CodePudding user response：

From docs for hconcat:

All of the matrices must have the same number of rows and the same depth.

Same for vconcat:

All of the matrices must have the same number of cols and the same depth.

Examine img1.shape and img2.shape. If you still need help, please share your images in your question.
