Hi.
When running Traffic counting with OpenCV.ipynb notebook the error is raised

AttributeError: module 'numpy' has no attribute 'float'.
`np.float` was a deprecated alias for the builtin `float`. To avoid this error in existing code, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.float64` here.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

... which is due to breaking change in numpy version 1.20.0

Looks like the installation should be done as pip install scikit-video instead of pip install sk-video.
What do you think?
