Ipython provides both a command line and browser based (notebook) interfaces. The development is quite fast, so the distribution provided packages tend to lag behind enough it makes sense to setup a python environment which incorporates the latest updates.

building an Ipython notebook environment

Login to a corn and make yourself an Ipython environment in glusterfs

mkdir -p /farmshare/user_data/$USER/ipythontest
cd /farmshare/user_data/$USER/ipythontest
virtualenv --system-site-packages devbranch
devbranch/bin/pip install --upgrade ipython
cp -p /farmshare/software/examples/ipython/audio.ipynb .

To run Ipython notebook environment, first start it up:

devbranch/bin/ipython notebook --pylab=inline --no-browser

You should see output similar to following:

2013-12-03 21:39:50.435 [NotebookApp] Created profile dir: u'/afs/ir.stanford.edu/users/b/i/bishopj/.config/ipython/profile_default'

2013-12-03 21:39:50.599 [NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).

Setup an ssh tunnel from your desktop system to the same corn system you ran the notebook on in previous step. In my case port 8888 and corn02.

ssh -L 8888:localhost:8888 corn02

You should see Notebooks1.png

Now click on Cluster and startup your cluster Notebooks2.png

Click back on the Notebook tab and you should see an audio notebook. click on this. Notebooks1.png

Now you can load up a notebook and "play" Notebooka1.png
