Hi there, some update in my progress. I've managed to run the sympy-live in my appengine, so it's clear that not only sympify work in GAE, but the full sympy.
But I don't know how to made the imports in order to make sympy work in my app, which in local works fine. Are there any dependences that I'm missing? Thanks!
