RecurrsionError for pydeps on sympy #33
Description
Hi, I was trying to give pydeps a try on a project which has sympy as a dependency and hit an error: RecursionError: maximum recursion depth exceeded while calling a Python object. I don't know if this is a bug in pydeps or sympy, but figured I'd report it here in case its something pydeps can handle. The error occurs with the default args, and with --show-cycles.
If there's any more debug info I can provide, let me know. Thanks!
