ImportError when using duecredit

Hello,

I've got a Git repo (https://github.com/seekrcentral/seekr2.git) that I'd like to add duecredit to, so that I and my users can cite our project and all our dependences.

First, I installed duecredit with pip install duecredit

Then, within seekr2/seekr2/modules/, I've downloaded stub.py wget -q -O due.py https://raw.githubusercontent.com/duecredit/duecredit/master/duecredit/stub.py

Then, since I have a module named common_base.py in that directory, I placed a citation in there:

from .due import due, Doi, BibTeX
due.cite(BibTeX("""
         @article{votapka2022seekr2,
         title={SEEKR2: Versatile multiscale milestoning utilizing the OpenMM molecular dynamics engine},
         author={Votapka, Lane W and Stokely, Andrew M and Ojha, Anupam A and Amaro, Rommie E},
         journal={Journal of chemical information and modeling},
         volume={62},
         number={13},
         pages={3253--3262},
         year={2022},
         publisher={ACS Publications}
         }
         """),
         description="Multiscale molecular kinetics and thermodynamics with milestoning.",
         path="seekr2/modules", cite_module=True)

But when I run, I get the following error and incomplete output:

python -m duecredit common_base.py

My package also imports more than just numpy (matplotlib and scipy), and when I attempt to set: export DUECREDIT_ENABLE=yes I still cannot see my package or the other listed (besides numpy).
