 There is something wrong with at least the py37-numpy subport on at least
 Mac OS X 10.7. Software that uses numpy
 [https://build.macports.org/builders/ports-10.7_x86_64-builder/builds/6548/steps

 IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

 Importing the numpy c-extensions failed.
 - Try uninstalling and reinstalling numpy.
 - If you have already done that, then:
   1. Check that you expected to use Python3.7 from
 "/opt/local/Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7",
      and that you have no directories in your PATH or PYTHONPATH that can
      interfere with the Python and numpy version "1.17.3" you're trying to
 use.
   2. If (1) looks fine, you can open a new issue at
      https://github.com/numpy/numpy/issues.  Please include details on:
      - how you installed Python
      - how you installed numpy
      - your operating system
      - whether or not you have multiple versions of Python installed
      - if you built from source, your compiler versions and ideally a
 build log

 - If you're working with a numpy git repository, try `git clean -xdf`
   (removes all files not under version control) and rebuild numpy.

 Note: this error has many possible causes, so please don't comment on
 an existing issue about this - open a new one instead.

 Original error was:
