Cloned¶

Description¶

Data obtained by training an imitation policy on the demonstrations from expert and human, then running the policy, and mixing data at a 50-50 ratio with the demonstrations. This dataset is provided by D4RL. The environment used to collect the dataset is AdroitHandRelocate-v1.

Environment Specs¶

The following table rows correspond to (in addition to the action and observation space) the Gymnasium environment specifications used to generate the dataset. To read more about what each parameter means you can have a look at the Gymnasium documentation https://gymnasium.farama.org/api/registry/#gymnasium.envs.registration.EnvSpec

This environment can be recovered from the Minari dataset as follows:

import minari

dataset = minari.load_dataset('D4RL/relocate/cloned-v2')
env  = dataset.recover_environment()


ID	AdroitHandRelocate-v1
Observation Space	`Box(-inf, inf, (39,), float64)`
Action Space	`Box(-1.0, 1.0, (30,), float32)`
entry_point	`gymnasium_robotics.envs.adroit_hand.adroit_relocate:AdroitHandRelocateEnv`
max_episode_steps	200
reward_threshold	None
nondeterministic	`False`
order_enforce	`True`
disable_env_checker	`False`
kwargs	`{'reward_type': 'dense'}`
additional_wrappers	`()`
vector_entry_point	`None`

Evaluation Environment Specs¶

This dataset doesn’t contain an eval_env_spec attribute which means that the specs of the environment used for evaluation are the same as the specs of the environment used for creating the dataset. The following calls will return the same environment:

import minari

dataset = minari.load_dataset('D4RL/relocate/cloned-v2')
env  = dataset.recover_environment()
eval_env = dataset.recover_environment(eval_env=True)

assert env.spec == eval_env.spec
