Keras implementation of a DQN agent for solving OpenAI's Flappy Bird environment

To install the environment, PLE and PyGame:

On OSX:

brew install sdl sdl_ttf sdl_image sdl_mixer portmidi  # brew or use equivalent means
conda install -c tlatorre pygame=1.9.2 # using Anaconda

On Ubuntu 14.04:

apt-get install -y python-pygame

More configurations and installation details on: http://www.pygame.org/wiki/GettingStarted#Pygame%20Installation

git clone https://github.com/ntasfi/PyGame-Learning-Environment.git
cd PyGame-Learning-Environment/
pip install -e .

and finally in order to use PLE as an OpenAI gym environment

pip install gym_ple

Given that the agent is implemented using Keras, having it installed may proove useful, to do so:

sudo pip install keras

As a backend for Keras I highly recommend gpu-enabled tensorflow

To train the agent simply run

python flappy_bird.py
