Very happy to explore your Dataviews Tutorial. Imagining really, really new to, well everything, python, linux, topographica, but a burning desire to get one's head around topographica and its many worthy parts some things can go wrong for the uninitiated (like myself, and soon my students...).
My first issues were with modules not found (dataviews), and fixed through appending sys.path for dataviews and param.
That said, in the section - SheetViews, the default backend selected is backend_tkagg.py, which leads to TclError: couldn't connect to display ":0". The sinusoid data is printed but not visualized. Putting %matplotlib inline, in a cell prior to plotting means all your work can be seen by us nubes.
Thanks for your documenting efforts.

Hi

If the IPython extension is working properly, you shouldn't be needing matplotlib inline. My first recommendation (as you are using Topographica) is to launch the notebooks with:

topographica -n

This should help get everything configured for you properly. If that doesn't work, try:

from dataviews import ipython

And see if there is a traceback - if there is, please post here so we can find the problem!
