Later, we'll run our IL algorithm on a revisited version of a famous game called Flappy Bird (https://en.wikipedia.org/wiki/Flappy_Bird). In this section, we'll give you all the commands needed to install it.

But before installing the environment of the game, we need to take care of a few additional libraries:

• In Ubuntu, the procedure is as follows:

$ sudo apt-get install git python3-dev python3-numpy libsdl-image1.2-dev libsdl-mixer1.2-dev libsdl-ttf2.0-dev libsmpeg-dev libsdl1.2-dev libportmidi-dev libswscale-dev libavformat-dev libavcodec-dev libfreetype6-dev
$ sudo pip install pygame

• If you are a Mac user, you can install the libraries with the following commands:

$ brew install sdl sdl_ttf sdl_image sdl_mixer portmidi 
$ pip install -c https://conda.binstar.org/quasiben pygame

• Then, for both Ubuntu and Mac users, the procedure is the following:

1. First, you have to clone PLE. The cloning is done with the following line of code:

git clone https://github.com/ntasfi/PyGame-Learning-Environment

PLE is a set of environments that also includes Flappy Bird. Thus, by installing PLE, you'll obtain Flappy Bird. 

2. Then, you have to enter the PyGame-Learning-Environment folder:

cd PyGame-Learning-Environment

3. And finally, run the installation with the following command:

sudo pip install -e .

Now, you should be able to use Flappy Bird.
