What did you try to do? I am running Ubuntu 12.04, with several versions of Python installed including 2.7 and 3.3. I have the following packages installed: ipython, ipython-notebook, ipython3, and ipython3-notebook. When I am developing most of these notebooks, I run 'ipython3 notebook'. When I need to make a cell using Python 2.7, I close the ipython3 server and run 'ipython notebook'. Am I missing something?
