python - 错误：“模块”对象没有属性“readNet”我该如何解决这个错误？

Question

我正在尝试按照以下代码中的相同步骤来了解如何使用 Yolo https://www.arunponnusamy.com/yolo-object-detection-openCV-python.html进行对象检测。我正在使用Python 2.7. 在我运行这部分代码后，我收到了这个错误：

AttributeError: 'module' object has no attribute 'readNet' 

我真的需要你的帮助来解决这个错误

import cv2
import argparse
import numpy as np

ap = argparse.ArgumentParser()

ap.add_argument('-i', '--image', required=False,default='D:/darknet/data/dog.jpg',help = 'path to input image')

ap.add_argument('-c', '--config',required=False,default='D:/darknet/cfg/yolov3.cfg',help = 'path to yolo config file')

ap.add_argument('-w', '--weights', required=False,default='D:/darknet/yolov3.weights',
                 help = 'path to yolo pre-trained weights')

ap.add_argument('-cl', '--classes', required=False,default='D:/darknet/yolov3.txt',
                help = 'path to text file containing class names')

args = ap.parse_args()

image = cv2.imread(args.image)

Width = image.shape[1]

Height = image.shape[0]

scale = 0.00392

classes = None

with open(args.classes, 'r') as f:
    classes = [line.strip() for line in f.readlines()]

COLORS = np.random.uniform(0, 255, size=(len(classes), 3))

net = cv2.dnn.readNet(args.weights, args.config)

blob = cv2.dnn.blobFromImage(image, scale, (416,416), (0,0,0), True,crop=False)

net.setInput(blob)
