add more kernels to python 3 jupyter notebooks with anaconda

this assumes you have installed Python 3 via Anaconda distribution.

Make Python 2 kernel available to Jupyter Notebook

  1. open a terminal and create a new python 2 environment: conda create -n py27 python=2.7
  2. activate the environment: linux source activate py27 or windows activate py27
  3. install the kernel in the env: conda install notebook ipykernel
  4. install the kernel for outside the env: ipython kernel install --user
  5. close the env: source deactivate
