Metaclass conflict when importing discretize

What was done

1. Using a new python 3.7.3 virtualenv, run pip install discretize
2. Start the python interpreter
3. run import discretize

What was seen

>>> import discretize
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/ianmacaulay/tmp/venv3/lib/python3.7/site-packages/discretize/__init__.py", line 2, in <module>
    from discretize.TensorMesh import TensorMesh
  File "/Users/ianmacaulay/tmp/venv3/lib/python3.7/site-packages/discretize/TensorMesh.py", line 15, in <module>
    InnerProducts, TensorMeshIO
TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases

What was expected Discretize should import properly.

OS: MacOS 10.14.6 python: 3.7.3 Version: 0.4.9

The only version that I was able to get to work was 0.4.4 on a clean install, although I was required to install numpy myself before I could install discretize

@prisae 0.4.10 works fine for me now. Installing matplotlib in 0.4.9 also fixed it. Thanks for getting this resolved so quickly

Can you do a pip install scooby and then in your Python environment a

import scooby
scooby.Report(['discretize', 'SimPEG'])

and post the output?
