Throws `RecursionError` on initial import

[msbc]

On initial import, a RecursionError is thrown. I have tried both installing pyvoro with pip install pyvoro and cloning and installing with python setup.py install --user. Both give the same result (see below).

System info:

gcc version 9.2.0 (Homebrew GCC 9.2.0)

Manually installing from the feature/python3 branch fixed this error for me on python3.6.

Hi, did you solve your problem? I encounter the same issue while using python 3.7

[liangtianumich]

pip install pyvoro will install the default master branch for pyvoro for python 2.7. If you are using python 3.X, you should use the branch for python 3 feature branch by git checkout feature/python3 .

Why doesn't the version on PyPI support python 3, when 2 has been deprecated?

[liangtianumich]

The owner's last commit is 2014 for mainstream python 2.X and did not maintain after that. he gave a patch for python 3.X thinking some people may need it.

Ok, I've been using pyvoro from https://pypi.org/project/pyvoro-mmalahe/ without issues. Posting the link here in case other users need to make pyvoro a package dependency.
