Code not working on Windows
I downloaded the folder as it is and installed all the requirements given in Requirements.txt and requirements-dev.txt
Still while running the code it is showing w=error.

This might help you...
I'm also on windows and had to manually set the download location for the webcam tracking script:
WEIGHTS_URL = 'https://github.com/opencv/opencv_3rdparty/raw/dnn_samples_face_detector_20170830/res10_300x300_ssd_iter_140000.caffemodel' WEIGHTS_PATH = 'C:\\Users\\user\\Downloads\\motpy-master\\motpy-master\\examples\\opencv_face_detector.caffemodel' CONFIG_URL = 'https://raw.githubusercontent.com/opencv/opencv/master/samples/dnn/face_detector/deploy.prototxt' CONFIG_PATH = 'C:\\Users\\user\\Downloads\\motpy-master\\motpy-master\\examples\\deploy.prototxt'
