Dependency installation

[Lansorian]

In the readme.md, when you say
pip install requirements.txt
I suppose you mean
pip install -r requirements.txt?

Also in the requirements.txt,
I think cv2 should be replaced by opencv-python

At least on my side doing so resolve the erros; if this is not a typo/bug but a version/enviornment thing,
please tell me more about it. Thanks.
