IPython is an interactive Python environment. Coupled with the "notebook" module, it provides a rich web interface.


Where is it

IPython notebook is available on the cluster in 2 environments : the custom build and CVMFS.

  • To load from the custom build [deprecated] :
source /software/sources/latestEnvironment.source
  • To load from CVMFS :

See IceCube Software Cluster#CVMFS

Launch a notebook

first, connect to the cluster. Set the correct environment and launch a notebook to which you will later connect to from your laptop:

ipython notebook --no-browser --pylab inline


When launching the notebook, the system will create a dedicated server for you. It will be running on a specific port chosen by the notebook itself. The launcher reports this port in the following way:

The IPython Notebook is running at: http://127.0.0.1:8888/

The port number you need it the number coming after the colon (:).

Now, open a new terminal on your laptop and create a tunnel to the machine where you instantiated the notebook. Fill in the correct port number in the following command:

ssh -L PORT_NUMBER:localhost:PORT_NUMBER uixx.iihe.ac.be

The tunnelled notebook is available in your browser by opening the url : http://localhost:PORT_NUMBER
