Python - numpy: No module named '_ctypes'

Question

I have to run a python 3 script on a centos 7 host. I've installed python3.8 side by side with python2 so it doesn't break yum.

When I'm running the script I need to run I get this error:

Traceback (most recent call last):
  File "A2PTestSuit.py", line 8, in <module>
    import pandas as pd
  File "/usr/local/lib/python3.8/site-packages/pandas/__init__.py", line 16, in <module>
    raise ImportError(
ImportError: Unable to import required dependencies:
numpy: No module named '_ctypes'

If I list the modules I see that pandas and numpy are installed:

python3 -m pip list
Package         Version
--------------- ----------
certifi         2019.11.28
chardet         3.0.4
DateTime        4.3
idna            2.8
numpy           1.18.1
pandas          0.25.3
pip             19.3.1
python-dateutil 2.8.1
pytz            2019.3
requests        2.22.0
setuptools      41.2.0
six             1.13.0
urllib3         1.25.7
zope.interface  4.7.1

How can I get past this error?

Another answer - stackoverflow.com/questions/27022373/… - suggests to yum install libffi-devel — Kacperito

I've tried that, but it looks like it's already installed: Package libffi-devel-3.0.13-18.el7.x86_64 already installed and lates t version Nothing to do I've installed all the other modules using pip. Can I mix pip and yum module installs like that? — bluethundr

You can try updating all of your packages in the command line using pip, or just use try: import ... except ImportError: continue

I fixed it by recompiling with the sudo make -j 8 command. No errors after recompiling with that command.

I've got same issue. Problem was solved after I change default interpreter (which was Python 3.8) in PyCharm
