模块“cv2.cv2”没有属性“cvtcolor”

Question

I never used python and openCV before and I don't know what is the problem.

from PIL import ImageGrab
import cv2
import time

last_time = time.time()
while(True):
        screen = np.array(ImageGrab.grab(bbox=(0,40, 640, 480)))
        print('Loop took {} second'.format(time.time()-last_time))
        cv2.imshow('window', cv2.cvtcolor(screen, cv2.COLOR_BRG2RGB))
        if cv2.waitKey(25) & 0xFF == ord('q'):
                cv2.destroyAllWindow()
                break

this is the code, can somebody help me understand the problem?

Answer 1

should be cvtColor as cvtcolor renamed to cvtColor
