In my environment, it seems to have gone up to the point where it starts once with the following library version.

% pip list
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

Note that NECOMATter is a project that is over 4 years old and is not currently maintained.
Also, as pip says, Python 2 will also end on January 1, 2020, so I can't find much sense to continue using this project.
