sinergym.utils.wrappers.NormalizeObservation

class sinergym.utils.wrappers.NormalizeObservation(*args: Any, **kwargs: Any)

__init__(env: Any, ranges: Dict[str, Sequence[Any]])

Observations normalized to range [0, 1].

Parameters:

env (Any) – Original Sinergym environment.
ranges (Dict[str, Sequence[Any]]) – Observation variables ranges to apply normalization (rely on environment).

Methods

`__init__`(env, ranges)	Observations normalized to range [0, 1].
`get_unwrapped_obs`()	Get last environment observation without normalization.
`observation`(obs)	Applies normalization to observation.

get_unwrapped_obs() → ndarray | None

Get last environment observation without normalization.

Returns:: Last original observation. If it is the first observation, this value is None.
Return type:: Optional[np.ndarray]

observation(obs: ndarray) → ndarray

Applies normalization to observation.
