Having the same issue !!!..

error: OpenCV(4.2.0) C:\projects\opencv-python\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 'cv::dnn::ReadProtoFromTextFile'

But even don't know how to rectify it...

[nidadinch]

Use your own path for deploy.prototxt in detect_mask_video.py

[Ritvik-Sapra]

Use correct and absolute path to the file. Can be found by looking at the file's property tab.

[Dark-Programm]

The backward slashes () just replace them with forward slashes (/).

Use the file path relative to current file.
...
It worked for me.
