---------------------------+--------------------
 On Mac OSX Sierra, I can load Python3.7 interactively. But it will not
 import numpy (py37-numpy 1.15.4_0+gfortran)

 I get the following:

 {{{python3.7

 Python 3.7.2 (default, Dec 30 2018, 09:00:52)
 [Clang 9.0.0 (clang-900.0.39.2)] on darwin

 >>> import numpy

 During handling of the above exception, another exception occurred:

 ImportError:
 Importing the multiarray numpy extension module failed.  Most
 likely you are trying to import a failed build of numpy.
 If you're working with a numpy git repo, try `git clean -xdf` (removes all
 files not under version control).  Otherwise reinstall numpy.

 Original error was: cannot import name 'multiarray' from 'numpy.core'
 (/opt/local/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6
 /site-packages/numpy/core/__init__.py)}}}

 Can you identify if I am doing something wrong or is this an issue with
 numpy?
