class Trajectory(obs, true_obs, action, reward, terminated, truncated, info)

Bases: object

Class representing a trajectory \((S_0, A_0, R_0, S_1, ..., S_n)\) in an environment.

__init__(obs, true_obs, action, reward, terminated, truncated, info)

Methods

__init__(obs, true_obs, action, reward, ...)

Attributes

done	Return whether the episode has ended (either terminated or truncated).
obs	The observations \((S_0, S_1, ..., S_n)\) in the trajectory.
true_obs	The true observations \((\hat{S}_0, \hat{S}_1, ..., \hat{S}_n)\) in the trajectory.
action	The actions \((A_0, A_1, ..., A_{n-1})\) taken in the trajectory.
reward	The rewards \((R_0, R_1, ..., R_{n-1})\) received in the trajectory.
terminated	Whether the episode terminated at each timestep in the trajectory.
truncated	Whether the episode was truncated at each timestep in the trajectory.
info	Additional information about the trajectory.

action: Any

The actions \((A_0, A_1, ..., A_{n-1})\) taken in the trajectory.

property done: Array

Return whether the episode has ended (either terminated or truncated).

info: dict[str, Any]

Additional information about the trajectory.

obs: Any

The observations \((S_0, S_1, ..., S_n)\) in the trajectory.

reward: Array

The rewards \((R_0, R_1, ..., R_{n-1})\) received in the trajectory.

terminated: Array

Whether the episode terminated at each timestep in the trajectory.

true_obs: Any

The true observations \((\hat{S}_0, \hat{S}_1, ..., \hat{S}_n)\) in the trajectory. These may differ from obs in environments that allow truncation.

truncated: Array

Whether the episode was truncated at each timestep in the trajectory.
