Example #3

def load_ipython_extension(ipython):

        rc.set('progress', 'progress_bar', '.'.join(
            (__name__, IPython2ProgressBar.__name__)))

Example #4

At the moment this only activates the improved progress bar.

Use ``%load_ext nengo.ipynb`` in an IPython notebook to load the extension.

Note
----

This IPython extension cannot be unloaded.
