pydstool

SciPy's solvers cannot handle events which are nearby, most return codes aren't documented, you cannot run the wrapped solvers in stepping control mode, you cannot give it a linear solver routine, etc. So it wraps established solvers but still only gives the very basic solving feature of it, and most of the details that made the methods famous are not actually available from SciPy's interface. And it wasn't Python 3 for pydstool. It's SciPy 1.0.0. Some of the recent maintenance for this stuff has actually come from the Julia devs though: https://github.com/robclewley/pydstool/pull/132

SciPy solvers are mostly interfaces to existing established solvers, and I’ve not had any problems with them. We’ve also used PyDSTool without problem, and it appears to support Python 3, https://github.com/robclewley/pydstool/blob/master/README.rs... If you think these are poorly maintained you should see XPPAUT, a tool still quite widely used.
