 :info:build IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS
 ISSUE!
 :info:build Importing the numpy c-extensions failed.
 :info:build - Try uninstalling and reinstalling numpy.
 :info:build - If you have already done that, then:
 :info:build   1. Check that you expected to use Python3.7 from
 "/opt/local/Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7",
 :info:build      and that you have no directories in your PATH or
 PYTHONPATH that can
 :info:build      interfere with the Python and numpy version "1.17.3"
 you're trying to use.
 :info:build   2. If (1) looks fine, you can open a new issue at
 :info:build      https://github.com/numpy/numpy/issues.  Please include
 details on:
 :info:build      - how you installed Python
 :info:build      - how you installed numpy
 :info:build      - your operating system
 :info:build      - whether or not you have multiple versions of Python
 installed
 :info:build      - if you built from source, your compiler versions and
 ideally a build log
 :info:build - If you're working with a numpy git repository, try `git
 clean -xdf`
 :info:build   (removes all files not under version control) and rebuild
 numpy.
 :info:build Note: this error has many possible causes, so please don't
 comment on
 :info:build an existing issue about this - open a new one instead.
 :info:build Original error was:
 dlopen(/opt/local/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7

 I am seeing this on Mojave and Xcode 11.2.
