We don't have such a program. Maybe we should reach out to NumFOCUS to see if any other projects have done similar things that we can emulate. > > Best regards, > Kevin > > Issues I've Encountered: > > I'm using parse_latex() to convert LaTEX into SymPy, but it looks like > some relational expressions still convert to "True" (e.g. "2+2=4" or > "2^3=8").

Regarding who to contact, I'm not sure. I would open an issue about this. If you want to CC people you can look at who has contributed to the latex parsing module recently. > > I'm having trouble with domains and solveset().

The issue tracker lets us keep track of the issue so we don't forget it.
