無法在函數“cv::dnn::ReadProtoFromTextFile”中打開“face_detector\deploy.prototxt”

穆罕默德·法赫米

我正在嘗試學習 python，以檢測是否有人使用過面具。

當我運行這段代碼時

prototxtPath = r"face_detector\deploy.prototxt"
weightsPath = r"face_detector\res10_300x300_ssd_iter_140000.caffemodel"
faceNet = cv2.dnn.readNet(prototxtPath, weightsPath)

maskNet = load_model("mask_detector.model")

print("[INFO] starting video stream...")
vs = VideoStream(src=0).start()

我有錯誤

---------------------------------------------------------------------------

---> 36 faceNet = cv2.dnn.readNet(prototxtPath, weightsPath)
     37 
     38 maskNet = load_model("mask_detector.model")

我試著用同樣的問題在谷歌上搜索，但我在某些文件中遇到了問題。我的 python 項目文件在C:\Users\mfahm\anaconda3\Test 中。我得到了錯誤的文件名嗎？

你必須確保文件deploy.prototxt和res10_300x300_ssd_iter_140000.caffemodel在正確的目錄，然後使用os.path.join

import os

prototxtPath = os.path.join(os.getcwd(), 'face_detector', 'deploy.prototxt')
weightsPath = os.path.join(os.getcwd(), 'face_detector', 'res10_300x300_ssd_iter_140000.caffemodel')

faceNet = cv2.dnn.readNet(prototxtPath, weightsPath)

print("[INFO] starting video stream...")
vs = VideoStream(src=0).start()
