我收到此错误，无法理解为什么会出现此问题。下面是代码和错误。

上次可打印锻炼的结果

[-8.54582258e-01  9.83741381e+02] left
[   0.776281243  -160.77584028] right

代码错误发生在make_coordinates，该行是

slope, intercept = line_parameters

这是完整的代码：

import cv2
import numpy as np

vid = cv2.VideoCapture('carDriving.mp4')

def processImage(image):
    gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
    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), (1200,height), (750,300)]
    ])
    mask = np.zeros_like(image)
    cv2.fillPoly(mask, polygons, 255)
    masked_image = cv2.bitwise_and(image, mask) 
    return masked_image

def display_lines(image, lines):
    line_image = np.zeros_like(image)
    if lines is not None:
        for …
