Exceptions:

`IncorrectPositionOfStorages`	This is a more precise exception than `EnvError` indicating that there is a mismatch in the number of storage unit at a substation.
`InsufficientData`	This exception is raised where there are not enough data compare to the size of the episode asked.
`InvalidBusStatus`	This is a more precise exception than `AmbiguousAction` indicating that the `grid2op.BaseAction.BaseAction` try to both "set" and "switch" some bus to which an object is connected.
`InvalidCurtailment`	This is a more precise exception than `AmbiguousAction` indicating that the `grid2op.BaseAction.BaseAction` try to apply an invalid curtailment strategy.
`InvalidLineStatus`	This is a more precise exception than `AmbiguousAction` indicating that the
`InvalidNumberOfGenerators`	This is a more precise exception than `AmbiguousAction` indicating that the `grid2op.BaseAction.BaseAction` is ambiguous because an incorrect number of generator tries to be modified.

`MultiEnvException`	General exception raised by `grid2Op.MultiEnv.MultiEnvironment`
`NoForecastAvailable`	This exception is mainly raised by the `grid2op.Observation.BaseObservation`.
`NonFiniteElement`	This is a more precise exception than `AmbiguousAction` indicating that an action / observation non initialized (full of Nan) has been loaded by the "from_vect" method.
`NotEnoughAttentionBudget`	This exception is raised when the player attempted to alert the "human operator" but it has not enough budget to do so.
`NotEnoughGenerators`	This is a more precise exception than `AmbiguousAction` indicating that there is not enough turned off generators to meet the demand.
`OnLines`	This is a more precise exception than `IllegalAction` indicating that the action is illegal due to setting
`OnLoad`	This is a more precise exception than `IllegalAction` indicating that the action is illegal due to setting wrong values to loads.
`OnProduction`	This is a more precise exception than `IllegalAction` indicating that the action is illegal due to setting wrong values to generators.

`SomeGeneratorAboveRampmax`	This is a more precise exception saying that, at the end of the simulation, some generator would have their production vary too much, which is not possible in practice.
`SomeGeneratorBelowPmin`	This is a more precise exception saying that, at the end of the simulation, some generator would have their production below pmin, which is not possible in practice.
`SomeGeneratorBelowRampmin`	This is a more precise exception saying that, at the end of the simulation, some generator would have their production vary too much, which is not possible in practice.
`UnitCommitorRedispachingNotAvailable`	attempt to use redispatching or unit commit method in an environment not set up.
`UnknownEnv`	This exception indicate that a bad argument has been sent to the `grid2op.make()` function.
`UnrecognizedAction`	This is a more precise exception than `AmbiguousAction` indicating that the `grid2op.BaseAction.BaseAction` is ambiguous due to the bad formatting of the action.
`UsedRunnerError`	This exception indicate that runner (object of `grid2op.Runner.Runner`) has already been used.
