Hullo List,
I have a fairly small expression (~500 variables). When I create a
Relation with it, Python informs me that Sympy has exceeded the max
recursion depth. Is there an intentional limit to expression sizes in
Sympy?
Please find attached a mini-script that highlights the issue I'm
encountering. You should be able to just run it:
$ python recreate_sympy_recursion_issue.py
Thanks,
Kevin
