Problem importing installed module

[Ian W. Scott]

When I try to import pytz at the top of my db.py model I'm getting the following error:

    No module named 'applications.paideia.modules.pytz'

"paideia" is the name of the application. I'm running python 3.7 and double-checked that pytz is accessible from the py3.7 interactive prompt. It is. So I don't understand why it's not being found.

This problem may be related to the fact that I'm using a brand-new apache/mod_wsgi setup. I don't know whether something in my apache configuration could be causing a problem. The welcome and admin apps work fine, though. It's only when I import a non-standard-library module.

But just in case, here's my server config:

(2.18.5-stable+timestamp.2019.04.08.04.22.03, Running on Apache/2.4.39 (Unix) mod_wsgi/4.6.7 Python/3.7, Python 3.7.4)
