numpy decorator import error

[gretzteam]

Using Python 3.8 on Ubuntu 20.04, getting the following import error:

File "/PyDSM/pydsm/NTFdesign/tests/test_NTFdesign_hybrid.py", line 27, in from numpy.testing import decorators as dec ImportError: cannot import name 'decorators' from 'numpy.testing' (/home/python3.8/site-packages/numpy/testing/init.py)

I fixed it by adding ._private to the numpy.testing module: from numpy.testing._private import decorators as dec
