AttributeError: module 'cv2.cv2' has no attribute 'fillpoly' 如何解决这个问题

Question

1 我收到错误，而不是安装所有依赖项，如 python3.6.2、numpy、opencv、open-contrib-python。 2. 错误-

    File "lane.py", line 23, in <module>
    cv2.imshow("result", region_of_interest(canny))
  File "lane.py", line 15, in region_of_interest
    cv2.fillpoly(mask, polygons, 255)
AttributeError: module 'cv2.cv2' has no attribute 'fillpoly'

3源代码-

import cv2
import numpy as np


def canny(image):
     gray = cv2.cvtColor(lane_image, cv2.COLOR_RGB2GRAY)
     blur = cv2.GaussianBlur(gray, (5,5), 0)
     canny = cv2.Canny(blur, 50, 150)
     return canny

def region_of_interest(image):
    height = image.shape[0]
    polygons= np.array([(200, height), (1100, height), (550, 250)])
    mask = np.zeros_like(image)
    cv2.fillpoly(mask, polygons, 255)
    return mask


image = cv2.imread('test_image.jpg')
lane_image = np.copy(image)
canny = canny(lane_image)

cv2.imshow("result", region_of_interest(canny))
cv2.waitkey(0)
