I am running IPython notebook on an ubuntu vm. Everything works great so far, except I'm unable to do interactive matplotlib plots.
The error I get is: TclError: no display name and no $DISPLAY environment variable
And I'm just trying to follow these super basic tutorials.

Any tips? I've done some research but nothing seems applicable to running iPython from an ubuntu machine. I know I'm overlooking something obvious.
After speaking with ThomasK about this, it seems I need to run %matplotlib nbaggs following %matplotlib inline from within iPython to get the interactivity from within my VM.
However, interactivity only came available in the latest release of matplotlib (1.4.x) and so I needed to upgrade from 1.3.x.
After running sudo pip install matplotlib --upgrade I got the following error in my .pip_log.
Any advice?

IPython has a cell magic, %%capture , which captures the stdout/stderr of a cell. With this magic you can discard these streams or store them in a variable. from __future__ import print_function import sys. By default, %%capture discards these streams. This is a simple way to suppress unwanted output.
Jupyter doesn't load or doesn't work in the browserTry disabling any browser extensions and/or any Jupyter extensions you have installed. Some internet security software can interfere with Jupyter. If you have security software, try turning it off temporarily, and look in the settings for a more long-term solution.
It is your expection that needs to be adapted. The Jupyter Notebook only shows what the last statement of a cell evaluates to. If you define a function, this does not evaluate to anything that could be displayed. So you can't see anything in the upper cell.
Jupyter Notebook can print the output of each cell just below the cell. When you have a lot of output you can reduce the amount of space it takes up by clicking on the left side panel of the output. This will turn the output into a scrolling window.
