jupyter-2.7 vs. ipython

[Nathan Brazil]

In my experience, “jupyter notebook” is the correct startup command.  Here is what I do, using Python 2.7:
Install pyenv (https://github.com/pyenv/pyenv)
pyenv install 2.7.14
sudo port install py27-virtualenv
mkdir jupyter
cd jupyter
pyenv virtualenv 2.7.14 jupyter
echo "jupyter" > .python-version
pip install jupyter
jupyter notebook
