A case of cyclic dependencies between PyPI packages

Scenario: PyOD Installation Using Archives on RHEL 7

We tried to install 'pyod' using the .TAR file.
pip install pyod-0.7.8.2.tar.gz

It has dependency on 'combo', specifically combo-0.1.0.tar.gz
pip install combo-0.1.0.tar.gz

ISSUE:
We notice that we are at a deadend with cyclic dependencies between these two packages. See the logs below:
