Getting several python kernels into JuPyter/IPython notebook using Anaconda

To get Jupyter notebooks to use several different Python kernels using Anaconda, so the following from the commandline:

$ conda create -n py27 anaconda python=2.7 
$ source activate py27 
$ conda install notebook ipykernel
$ ipython kernel install

In the first line, the -n py27 sets the name of the new environment we create to py27. This is a handy name for a Python 2.7 environment. anaconda denotes the packages we want installed. The anaconda package contains all the scientific packages you'd expect (numpy, scipy, matplolib, sklearn, etc.) python=2.7 tells conda to create the environment with python version 2.7

The second line switches you to the new virtual environment.

Third and fourth line installs the kernel into IPython notebook.
