Great resources in the replies. If you want an environment to run code in w/o much setup, try our free service:
it has Py2, Py3, R, F#, anaconda, TF, CNTK, etc. pre-installed.
There are some ML tutorials on it already + you can use the "load from github" feature to load, run, edit, ... many of the great tutorials already on github.
Other similar environments include colab by google and cocalc.
