Can't open "face_detector\deploy.prototxt" in function 'cv::dnn::ReadProtoFromTextFile'

November 26, 2021

I’m trying to learn python, for detect someone used mask or not.

when i run this code

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()

i got error

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

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

error: OpenCV(4.5.4) D:\a\opencv-python\opencv-python\opencv\modules\dnn\src\caffe\caffe_io.cpp:1126: error: (-2:Unspecified error) FAILED: fs.is_open(). Can't open "face_detector\deploy.prototxt" in function 'cv::dnn::ReadProtoFromTextFile'

i tried searching on google with the same problem, and i got problem in certain file. My python project file is in C:\Users\mfahm\anaconda3\Test. Am I getting the wrong filename?

>Solution :

You have to make sure that the file face_detector\deploy.prototxt and face_detector\res10_300x300_ssd_iter_140000.caffemodel are in the correct directory, then use 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()
