from abc import ABC, abstractmethod
This class is a base class that determines whether or not an action is legal in certain environment.
See the definition of :func:`BaseRules.__call__` for more information.
Basically, this is an empty class with an overload of the __call__ operator that should return ``True`` or ``False``
depending on the legality of the action.
In :class:`grid2op.Environment`, only action of the users are checked for legality.
def __call__(self, action, env):
As opposed to "ambiguous action", "illegal action" are not illegal per se.
They are legal or not on a certain environment. For example, disconnecting
a powerline that has been cut off for maintenance is illegal. Saying to action to both disconnect a
powerline and assign it to bus 2 on it's origin end is ambiguous, and not tolerated in Grid2Op.
The action of which the legality is tested.
The environment on which the action is performed.
Whether the action is legal or not
The cause of the illegal part of the action (should be a grid2op exception)
[docs] def can_use_simulate(self, nb_simulate_call_step, nb_simulate_call_episode, param):
This function can be overriden.
It is expected to return either SimulateUsedTooMuchThisStep or SimulateUsedTooMuchThisEpisode if the number of calls to `obs.simulate`
is too high in total or for the given step
