The environment for the self-driving car

The environment for the self-driving car is CarRacing-v0 from the OpenAI Gym. The states presented to the agent from this OpenAI environment are images from the front of the simulated car in CarRacing-v0. The environment also returns a reward based on the action taken by the agent at a given state. We penalize the reward if the car treads on grass and also normalize the reward to be in the range of (-1,1) for stable training. The detailed code for the environment is as below
