Statistical tests depend on `tkinter`

[jsiegle]

I used pip to install zetapy in a Python 3.10 conda environment. When I run:

from zetapy import zetatest

it fails when trying to import zetapy.plot_dependencies because tkinter is not installed. This should either be included as a dependency when installing via pip, or (ideally) the plotting functions should be decoupled from the statistical tests.

Hi Josh,

tkinter is part of the standard Python library so almost all users will have it installed by default already. I assume you're using some custom minimal conda environment that doesn't have tkinter installed already. I tried adding tkinter to the install dependencies but it crashes because it's not installable via pip. I'll look into decoupling the plotting functions from the statistical tests but for now the best I could do is add a warning in the __init__ that tells users who don't have tkinter to install or activate it in their environments.

You're right -- I'm using a conda environment on Code Ocean that doesn't include tkinter. I totally forgot that this library is usually available by default.

To get around the error, I just copied the code I needed and ran it separately from the zetapy package.
