无法打开.prototxt和.caffemodel文件

Question

我正在尝试使用这段代码来使用youtube视频检测年龄和性别，但无法读取.protxt和.caffemodel文件。

import pafy
import cv2
import numpy as np
url = 'https://www.youtube.com/watch?v=cQ54GDm1eL0'
vPafy = pafy.new(url)
play = vPafy.getbest(preftype="mp4")

cap = cv2.VideoCapture(play.url)
cap.set(3, 480) #set width of the frame
cap.set(4, 640) #set height of the frame

MODEL_MEAN_VALUES = (78.4263377603, 87.7689143744, 114.895847746)
age_list = ['(0, 2)', '(4, 6)', '(8, 12)', '(15, 20)', '(25, 32)', '(38, 43)', '(48, 53)', '(60, 100)']
gender_list = ['Male', 'Female']

def load_caffe_models():

  age_net = cv2.dnn.readNetFromCaffe('/content/drive/My Drive/Colab/deploy_age.prototxt', '/content/drive/My Drive/Colab/age_net.caffemodel')
  gender_net = cv2.dnn.readNetFromCaffe('/content/drive/My Drive/Colab/deploy_gender.prototxt', '/content/drive/My Drive/Colab/gender_net.caffemodel')
  return(age_net, gender_net)

def video_detector(age_net, gender_net):
  font = cv2.FONT_HERSHEY_SIMPLEX

if __name__ == "__main__":
  age_net, gender_net = load_caffe_models()
  video_detector(age_net, gender_net)
  cap.read()

我遇到以下错误：

错误：OpenCV（4.1.2）/io/opencv/modules/dnn/src/caffe/caffe_io.cpp:1121：错误：（-2：未指定的错误）失败：fs.is_open（）。无法在函数“ ReadProtoFromTextFile”中打开“ / content / drive /我的驱动器/Colab/deploy_age.prototxt”

Answer 1

问题在于，目录'/content/drive/My Drive/Colab/deploy_age.prototxt'中没有这样的文件。

请确保它在该目录中可用。

谢谢！
