colab face mask implementation?

I was trying to implement face mask detecting system from this blog. I got an error in the detect_mask_image.py file:

File "/content/drive/My Drive/mask/face-mask-detector/detect_mask_image.py", line 32, in <module>
    net = cv2.dnn.readNet(prototxtPath, weightsPath)
cv2.error: OpenCV(4.1.2) /io/opencv/modules/dnn/src/caffe/caffe_io.cpp:1121: error: (-2:Unspecified error) FAILED: fs.is_open(). Can't open "face_detector/deploy.prototxt" in function 'ReadProtoFromTextFile'

Why this error?

Solution

  • If you are using Colab to detect a live video from your webcam then you have to make some changes to allow WEB APIs to access the local hardware such as the webcam.
