As you say, there appears to be no sense of urgency in the Trilinos community
to make the upgrade. Unfortunate to say the least.
“…need to be on Python 3 for some reason”: I am evangelizing about Python to
students, postdocs, and senior colleagues, but I cannot in good conscience
recommend Py2, because of its looming obsolescence (Py3 is now seven years old!)
Running ‘2to3’ on the source code and building from there: this is expert-level
stuff, from the perspective of your typical geoscientist, and not feasible
except for the very dedicated. It’s a huge barrier to that key step in getting
people interested: playing with demos before investing big efforts to get to
know the tool.
Vaguely related: one of the big scientific Python holdouts against Py3
migration, VTK, is inching closer to making the jump, which means MayaVi will
follow shortly. So the last missing essential viz tools will soon be
Py3-capable. See thread here=
