Numpy Import error

[gbtron]

I was running into this error after installing all dependencies and calling rearrange.py
ImportError: numpy.core.multiarray failed to import (auto-generated because you didn't call 'numpy.import_array()' after cimporting numpy; use '<void>numpy._import_array' to disable if you are certain you don't need it).

I needed to install numpy version 1.20.0 for this to be resolved.
