I want to know the observation specification CartPole-v0in OpenAI Gym ( https://gym.openai.com/ ).
For example, in the following code output observation. One observation is similar to [-0.061586 -0.75893141 0.05793238 1.15547541]I want to know what the numbers mean. And I want any way to find out the specification of others Environments, such as MountainCar-v0, MsPacman-v0etc.
I tried to read https://github.com/openai/gym , but I don't know that. Could you tell me how to find out the specifications?
import gym
env = gym.make('CartPole-v0')
for i_episode in range(20):
observation = env.reset()
for t in range(100):
env.render()
print(observation)
action = env.action_space.sample()
observation, reward, done, info = env.step(action)
if done:
print("Episode finished after {} timesteps".format(t+1))
break
(from https://gym.openai.com/docs )
