If Sage is installed on your computer, then in a terminal, run

this will lauch the Python that comes with Sage, and it will know where sage is. Then you can

If Sage is installed on your computer, then in a terminal, you can run IPython by typing:

$ sage -ipython

This will lauch the Python that comes with Sage, and it will know where Sage is. Then you can

%load_ext sage

To get the IPython notebook, type the following in a terminal:

$ sage -ipython notebook

You might get an import error complaining about the version of pyzmq:

ImportError: IPython.html requires pyzmq >= 2.1.11

To address that, you will need to install pyzmq, see which I did by just typing:

$ sage -i zeromq
$ sage -i pyzmq

$ sage -ipython notebook

Thank you for your question, I'm happy that I got this webpage by Jose Guzman for instructions.

[EDITED: my initial answer was about plain addressed IPython but failed to address the specific question about IPython notebook]not the IPython notebook.]

To address that, you will need to install pyzmq, which I did by just typing:

$ sage -i zeromq
$ sage -i pyzmq

and you can then I was able to successfully launch the IPython notebook by typing:

$ sage -ipython notebook

Once you have launched the IPython notebook in this way, you can

%load_ext sage

Thank you for your question, I'm happy that I got this working!

Sage in IPython and IPython notebook

You can use Sage inside IPython and IPython notebook by loading the Sage extension, which will also load the Sage preparser and let you use Sage commands in IPython or IPython notebook just as you would in Sage itself.

For this, just in the IPython provided with Sage (so it knows where Sage is), type

%load_ext sage

in To run the IPython provided with Sage, so it knows where Sage is. To run that particular IPython type in a terminal, typeterminal

$ sage -ipython

or, if you want the IPython notebook,

$ sage -ipython notebook

Note that for Sage versions older than 6.2.beta8, instead of %load_ext sage you should type

 %load_ext sage.misc.sage_extension

Dependencies of the Sage extension

The dependencies are the Tornado web framework, as well as ZeroMQ and its Python bindings Python bindingsPyZMQ PyZMQ..

If ZeroMQ and PyZMQ are not installed, you will get an import error like

ImportError: IPython.html requires pyzmq >= 2.1.11

If ZeroMQ and PyZMQ are installed, but Tornado is not installed, you will get an attribute error like

start_ipython()
File "/sage-6.2-i686-Linux/local/lib/python2.7/site-packages/numpy/lib/polynomial.py", line 11, in <module> import numpy.core.numeric as NX.
AttributeError: 'module' object has no attribute 'core'.

Recent versions of Sage ship Tornado, and upcoming versions will ship ZeroMQ and PyZMQ.

Installing Tornado

Tornado is included in Sage from 6.2.beta5 on. It if you have an older Sage, the simplest is to upgrade to the current version! At this day (2014-07-12), Sage 6.2 and Sage 6.3.beta5 are available.

For Why not get the latest release (Sage 6.2) or development release (Sage 6.3.beta5).

Or, for an older Sage, install Tornado as explained on the Tornado installation page. Under Linux, you could:can:

$ sudo apt-get install uuid-dev
$ sage -sh
$ easy_install-2.7 tornado

Installing zeromq and pyzmq

These will be shipped with Sage 6.3 when it is released.

Until then, just type this in a terminal (requires web access, and assumes sage points to your Sage):

$ sage -i zeromq
$ sage -i pyzmq

should also work.]
