Setup Guide

Pre-requisites: git, python 2.7.X, virtualenv, pip (7.1.X recommended)

  • If you're using Ubuntu, here are all the packages you'll need before you can proceed
  $ sudo apt-get install python2.7 python-dev build-essential curl libatlas-base-dev gfortran
  $ sudo apt-get install libfreetype6-dev libpng-dev libjpeg-dev
  • Clone the repo from GitHub

    $ git clone https://github.com/rouseguy/intro2deeplearning.git
    $ cd intro2deeplearning
    
  • Create python virtual environment

    $ virtualenv env
    $ source env/bin/activate
    
  • Install requirements using pip

    $ pip install -r requirements.txt
    

    Use

    requirements_linux.txt
    instead of
    requirements.txt
    if you're on linux
  • When the requirements are being downloaded / installed, Fetch the datasets simultaneously

    $ sh download_data.sh
    
  • Run check_env.py script to test the dependencies

    $ python check_env.py
    

    Output should look like this

    [ OK ] scipy version 0.15.1
    [ OK ] PIL version 1.1.7
    [ OK ] keras
    [ OK ] IPython version 4.0.0
    [ OK ] theano version 0.7.0
    [ OK ] numpy version 1.9.2
    [ OK ] pandas version 0.16.2
    [ OK ] gensim version 0.10.3
    [ OK ] sklearn version 0.16.1
    

    This means you have all the dependencies installed and you're ready to start.

  • Run the notebook

    $ cd notebooks
    $ ipython notebook
    

    This opens your default browser which displays the list of notebooks in the current directory.

    Open 1. Introduction to Artificial Neural Networks.ipynb. Now, run the first cell with imports in the notebook (shift + enter). If you have all the dependencies installed, this should run without any errors.

Note: We only support Ubuntu Linux (Tested) & OSX environments. We strongly recommend Windows users to have a VM running Linux, and then install these requirements on that VM.
