I have been trying to identify the range of each feature in MuJoCo's Half Cheetah environment. The only relevant piece of information I can find is the xml file. Does anyone know where can I locate the max and min of each feature in the state feature vector?

The observation_space is set in this file when this line is called (for HalfCheetah env)

To check the observation_space of any environment:

import gym
env = gym.make('CartPole-v0') # change the env name here
print('Max of observation_space:',env.observation_space.high)
print('Min of observation_space:',env.observation_space.low)

Output:

Max of observation_space: [4.8000002e+00 3.4028235e+38 4.1887903e-01 3.4028235e+38]
Min of observation_space: [-4.8000002e+00 -3.4028235e+38 -4.1887903e-01 -3.4028235e+38]

  • The observation space is different from state space. For instance, in mujoco humanoid, the dimension of state space is 17. However, the dimension of the observation space reaches 376. – Teddy Jul 18 '19 at 13:21
