 First step: installing python, jupyter, etc.

   I have several python versions on hardmaple, from apple, anaconda, and homebrew.
   I continue to need to tweak python versions and installation setups - a pain.
   For this project I'm using the one in /usr/local/opt/python3, python 3.6.5

   (It used to be that the regular python didn't come with numpy etc and
   that pip or whichever package manager hit errors when installing all that.
   So for a time I was using conda as my default. Now it seems that virtualenv
   and pip and the regular tools - which ones are "standard" seems to be somewhat
   controversial, see for example
   https://towardsdatascience.com/which-python-package-manager-should-you-use-d0fd0789a250
   - will install the numerical pstuff.)

 $ cd /usr/local/opt/python3
 $ ./pip3 install --upgrade pip
 $ ./pip3 install virtualenv
 $ which virtualenv
 /usr/local/bin/virtualenv
 $ virtualenv --version
 $ virtualenv --help (installed with /usr/local/opt/python/bin/python3.6)

 $ cd ~/sugar/academics/term/2018-09-fall/
 $ virtualenv env
 $ . env/bin/activate      # activate virutual python
 (env) $ which pip
 /Users/mahoney/sugar/academics/term/2018-09-fall/machine_learning/env/bin/pip
 (env) $ which python
 /Users/mahoney/sugar/academics/term/2018-09-fall/machine_learning/env/bin/python
 Python 3.6.5

 (env) $ pip install jupyter matplotlib numpy panda scipy scikit-learn
 ...

 Note that after this, "python", "python3", "python3.6" are all the same:

 $ ls -al ./env/bin/py*

 lrwxr-xr-x  1 mahoney  staff      9 Jun  1 17:04 ./env/bin/python -> python3.6
 -rwxr-xr-x  1 mahoney  staff   2387 Jun  1 17:04 ./env/bin/python-config
 lrwxr-xr-x  1 mahoney  staff      9 Jun  1 17:04 ./env/bin/python3 -> python3.6
 -rwxr-xr-x  1 mahoney  staff  13068 Jun  1 17:04 ./env/bin/python3.6

 $ pip --version
 pip 10.0.1 ... (python 3.6)

 $ pip3 --version
 pip 10.0.1 ... (python 3.6)

 Also "pip" and "pip3" are the same

 The "Hands-on with Machine Learning ..." code and examples are
 in a github repo which I've clone here :

 $ git clone https://github.com/ageron/handson-ml.git

And then to launch the notebooks :

 $ jupyter notebook &
