Getting Started

Python Installation

Windows Installation

• For windows, the easiest thing to do is to install a distribution of python, and not just the raw python installation.

• One of the most popular distributions of Python is Anaconda (https://www.anaconda.com/download/)

• Download the 3.6 version (because more future compatibility)

  • For our purposes, we don't care as long as version is greater that 2.7

• Follow Installation instructions

  • Add it to your path, as that would make life so much easier.
  • Do it during the installation
  • or if you know what you're doing, set it later. [Not Recommended]

Linux Installation

• Assuming that you're an expert
  • sudo apt-get install python3.6
  • sudo apt-get install jupyter-notebook python-scipy python-spyder

Environment Setup

Anaconda (Windows)

• Open up Anaconda Navigator
• If it asks you to make a virtual environment, do that with the default settings
• Open up an anaconda prompt
• install the required packages conda install seaborn scikit-learn matplotlib *// [Optional]// if you like a scientific IDE - conda install spyder

Linux

• if you do not have a virtual-env : sudo pip install matplotlib seaborn scikit-learn scipy numpy notebook

• if you do have a virtual env, skip the sudo

• Cheers! You're ready to go! Open up spyder or notebook
