Importing the numpy c-extensions failed.

Hi!

Thank you for the super interesting package. I successfully installed it on my local Anaconda machine running on a Windows 10 machine. Now I am currently trying to run genewalk on our cluster (Ubuntu, 2.6.32-431.20.3.el6.x86_64).

genewalk --project qki --genes /home/gitpycode/Documents/genes.csv --id_type mgi_id

I already set up the whole installation multiple times using virtual environments and trying different versions of python (3.5.0 and 3.7.0) and always get the same error message:

Traceback (most recent call last):
  File "/home/gitpycode/gwalk1/lib/python3.7/site-packages/numpy/core/__init__.py", line 17, in <module>

During handling of the above exception, another exception occurred:

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 "/home/gitpycode/gwalk1/bin/python3",
     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: PyCapsule_Import could not import module "datetime"

Segmentation fault

Can somebody help me to identify the problem? Thank you for your help!
