sinergym.utils.wrappers.DatetimeWrapper

class sinergym.utils.wrappers.DatetimeWrapper(env: Env)

Wrapper to transform datetime variables into a more useful representation: - ‘day_of_month’ is replaced with ‘is_weekend’ (1 if weekend, 0 otherwise). - ‘hour’ is replaced with its sine and cosine encoding. - ‘month’ is replaced with its sine and cosine encoding. The observation space is updated automatically.

__init__(env: Env)

Constructor for the observation wrapper.

Parameters:

env – Environment to be wrapped.

Methods

__init__(env)	Constructor for the observation wrapper.
class_name()	Returns the class name of the wrapper.
close()	Closes the wrapper and env.
get_wrapper_attr(name)	Gets an attribute from the wrapper and lower environments if name doesn't exist in this object.
has_wrapper_attr(name)	Checks if the given attribute is within the wrapper or its environment.
observation(obs)	Transforms the observation to replace time variables with encoded representations.
render()	Uses the render() of the env that can be overwritten to change the returned data.
reset(*[, seed, options])	Modifies the env after calling reset(), returning a modified observation using self.observation().
set_wrapper_attr(name, value, *[, force])	Sets an attribute on this wrapper or lower environment if name is already defined.
step(action)	Modifies the env after calling step() using self.observation() on the returned observations.
wrapper_spec(**kwargs)	Generates a WrapperSpec for the wrappers.

Attributes

action_space	Return the Env action_space unless overwritten then the wrapper action_space is used.
logger
metadata	Returns the Env metadata.
np_random	Returns the Env np_random attribute.
np_random_seed	Returns the base environment's np_random_seed.
observation_space	Return the Env observation_space unless overwritten then the wrapper observation_space is used.
render_mode	Returns the Env render_mode.
spec	Returns the Env spec attribute with the WrapperSpec if the wrapper inherits from EzPickle.
unwrapped	Returns the base environment of the wrapper.

logger = <Logger WRAPPER DatetimeWrapper (INFO)>
