This project is part of the Udacity Reinforcement learning nano degree course . The objective for this project is to train an RL agent to navigate through a rectangular field with yellow and blue bananas, the aim of the agent is to pick only yellow (ripe) bananas while avoiding blue (unripe ) bananas.
A reward of +1 is provided for collecting a yellow banana, and a reward of -1 is provided for collecting a blue banana. Thus, the goal of your agent is to collect as many yellow bananas as possible while avoiding blue bananas.
The state space has 37 dimensions and contains the agent's velocity, along with ray-based perception of objects around agent's forward direction. Given this information, the agent has to learn how to best select actions. Four discrete actions are available, corresponding to:
0- move forward.1- move backward.2- turn left.3- turn right.
The task is episodic, and in order to solve the environment, your agent must get an average score of +13 over 100 consecutive episodes.

Download the environment from one of the links below. You need only select the environment that matches your operating system:
- Linux: click here
- Mac OSX: click here
- Windows (32-bit): click here
- Windows (64-bit): click here
(For Windows users) Check out this link if you need help with determining if your computer is running a 32-bit version or 64-bit version of the Windows operating system.
(For AWS) If you'd like to train the agent on AWS (and have not enabled a virtual screen), then please use this link to obtain the environment.

Place the file in the DRLND GitHub repository, in the
p1_navigation/folder, and unzip (or decompress) the file.
You can get started using the DQN code for the 'LunarLander-v2' solutions from the Udacity repository
After the instalation of the unity environments from the steps above , you should have python 3.6 and above and pytorch and other necessary dependancies installed
