Spaces
Spaces describe valid actions (F forces) and observations (cart pole angle θ). This concept of observations will be covered in detail in the next subsection. Every environment has two spaces attached:
- Action space: This is characterized by a set of state variables under the env.action_space object. This space defines the possible actions an agent is allowed to take. For the case of the cart pole, there is only one variable: to apply a lateral force, F.
- Observation space: This describes the physical state of the agent, that is, the angular position of the cart pole, θ. Operationally, it is a set of state variables under the env.observation_space object.
Let's now describe the concept of observations in order to get a full understanding ...
