pytest fail after installing orbitdeterminator on MacPro (2019)

[OrbitalMechanic]

Attempting to install Orbitdeterminator on a Mac Pro (2019) running Mac OS X Catalina (10.15.6) under the Anaconda environment.

I began the installation by creating an environment for Orbitdeterminator called OrbDet under Python 3.6. The installation was successful as depicted in the listing that follows.

I attempted to install Orbitdeterminator under Python 3.7. I was successful at installing Orbitdeterminator from the test I ran:

Hi @OrbitalMechanic,
as far as I was able to see, the tests had paths leading to nowhere.
I opened this PR for it #206 and it solved (at least my) problems. I still need to check for the check_sgp4 for what that is used #207
But I think it was these artifacts I also see in your copied logs.

For example the lamberts_kalman.py is in .kep_determinator and adding the orbitdeterminator before caused problems for me.
from orbitdeterminator.kep_determination import lamberts_kalman
