如何修复错误“模块'cv2.cv2'没有属性setMouseCallBack？”

Question

"I'm trying to implement setMouseCallBack function using which I want to get the co-ordinate value of the location of image on which the mouse is left-clicked. I wrote the code. But on running, it shows the error that "module 'cv2.cv2' does not have attribute setMouseCallBack". I already ran the command : pip install opencv-contrib-python as suggested in some other answers, but still it is not working.

The code is given below:

import numpy as np
import cv2

def click_event(event,x,y,flags,param):
    if event==cv2.EVENT_LBUTTONDOWN:
        font=cv2.FONT_HERSHEY_SIMPLEX
        coordinate=str(x)+', '+str(y)
        cv2.putText(img,coordinate,(x,y),font,.5,(255,255,0),2)
        cv2.imshow('image',img)

img=np.zeros((512,512,3),dtype='uint8')
cv2.imshow('image',img)

cv2.setMouseCallBack('image',click_event)

cv2.waitKey(0)
cv2.destroyAllWindows()

Answer 1

cv2.setMouseCallback('image', click_event)

B 不是资本。
