If possible, please consider moving away from the use of Epydoc. Epydoc is
basically unmaintained upstream. Also, it is only supported for Python 2,
so it will reach its end of life along with Python 2 sometime in 2020.
I will continue to maintain the Epydoc packages in Debian as long as I can,
acting as de facto upstream. However, once Python 2 is unsupported in
Debian, I'm not sure that we'll have too many options to keep it alive.
Migrating it to Python 3 is a fairly large job that I don't have the time or
the expertise to take on right now.
For my own Python code, I have recently converted to Sphinx using the
Napolean plugin. At [1], I can offer you a hack-ish script to convert
common Epydoc markup to Google-style docstrings. It's not perfect, but it
would get you much of the way toward working code.
