The installation procedure for this package is quite strange. Running
setup.py install will install the libraries, but then the scripts need to be run directly--so you end up needing two copies of the source code.
Please have setup.py install the necessary scripts by setting the
scripts parameter in the
setup function. See https://docs.python.org/3/distutils/setupscript.html#installing-scripts
or use entrypoints https://packaging.python.org/guides/distributing-packages-using-setuptools/#entry-points.
python setup.py install will provide a working installation on its own.
