python - What does the ValueError : could not broadcast from input array(1) to input array(2) mean? - 


import numpy np import cv2 matplotlib import pyplot plt while(1):     img=cv2.imread('d:\img_0590_1.jpg')         ball = img[278:104, 330:158]     img[181:355, 100:274] = ball      cv2.imshow('img',img)      if cv2.waitkey(10) & 0xff == ord('q'):             break cv2.destroyallwindows()

this code giving above mentioned error. problem?

the first number in slice needs smaller second. turn

ball = img[278:104, 330:158]

into

ball = img[104:278, 158:330]

also dimensions don't match. ball 172 pixels wide, , you're putting slice 174 pixels wide
