The easiest way is to first install python only CNTK (instructions). There are seven discrete actions here that correspond to different directions in which the quadrotor can move in (six directions + one hovering action). Fundamentally, reinforcement learning (RL) is an approach to machine learning in which a software agent interacts with its environment, receives rewards, and chooses actions that will maximize those rewards. In most cases, existing path planning algorithms highly depend on the environment. For this purpose, AirSim also exposes APIs to retrieve data and control vehicles in a platform independent way.
