 # Installation

 The code in the tutorial has been written using Python 3; many of the dependencies may not be available for Python 2.7.
 
 We **strongly recommend** using the conda Python distribution. You can install either [miniconda](https://conda.io/miniconda.html) (much smaller, only essential packages) or the full [anaconda distribution](https://www.continuum.io/downloads) (very extensive, but very, very large).
