Describe the bug
I created a new conda environment, installed numpy, then ran python setup.py develop on current develop branch. When I tried to import pysat it didn't work.

To Reproduce
Steps to reproduce the behavior:

1. conda create --name testingcdaac python=3.8.2 --channel conda-forge
2. conda install numpy

(testingcdaac) russellstoneback@Russells-Pro Code % cd pysat

4. Try importing pysat
