Copying my comment from the Software Carpentry Github thread here:

We don't have an automated conversion tool for notebooks ourselves - we
don't curate enough notebooks ourselves to really need one. However, it
should be feasible to write something that loads a notebook, runs 2to3 on
each of the code cells, and saves it again. I'm happy to help build that.
It's not entirely trivial, though:

   - Some changes should only be done once per notebook, e.g. adding from
   __future__ imports.
   - IPython special syntax, e.g. %magics might break the parser 2to3 is
