v1.10.3

  • [BREAKING] env.chronics_hander.set_max_iter(xxx) is now a private function. Use
    env.set_max_iter(xxx) or even better env.reset(options={"max step": xxx}).
    Indeed, env.chronics_hander.set_max_iter() will likely have
    no effect at all on your environment.
  • [BREAKING] for all the Handler (eg CSVForecastHandler) the method set_max_iter is
    now private (for the same reason as the env.chronics_handler). We do not recommend to
    use it (will likely have no effect). Prefer using env.set_max_iter instead.
  • [BREAKING] now the runner.run() method only accept kwargs argument
    (because it should always have been like this)
  • [BREAKING] to improve pickle support and multi processing capabilities, the attribute
    gym_env.observation_space._init_env and gym_env.observation_space.initial_obs_space
    have been deleted (for the Dict space only, for the other spaces like the Box they
    were not present in the first place)
  • [BREAKING] in the GymEnv class now by default the underlying grid2op environment has no
    forecast anymore in an attempt to make this wrapper faster AND more easily pickle-able. You can
    retrieve the old behaviour by passing gym_env = GymEnv(grid2op_env, with_forecast=True)
  • [FIXED] a bug in the MultiFolder and MultifolderWithCache leading to the wrong
    computation of max_iter on some corner cases
  • [FIXED] the function cleanup_action_space() did not work correctly when the "chronics_hander"
    was not initialized for some classes
  • [FIXED] the _observationClass attribute of the "observation env" (used for simulate and forecasted env)
    is now an Observation and not an Action.
  • [FIXED] a bug when deep copying an "observation environment" (it changes its class)
  • [FIXED] issue on seed and MultifolderWithCache which caused
    #616
  • [FIXED] another issue with the seeding of MultifolderWithCache: the seed was not used
    correctly on the cache data when calling chronics_handler.reset multiple times without
    any changes
  • [FIXED] Backend now properly raise EnvError (grid2op exception) instead of previously
    EnvironmentError (python default exception)
  • [FIXED] a bug in PandaPowerBackend (missing attribute) causing directly
    #617
  • [FIXED] a bug in Environment: the thermal limit were used when loading the environment
    even before the "time series" are applied (and before the user defined thermal limits were set)
    which could lead to disconnected powerlines even before the initial step (t=0, when time
    series are loaded)
  • [FIXED] an issue with the "max_iter" for FromNPY time series generator
  • [FIXED] a bug in MultiMixEnvironment : a multi-mix could be created even if the underlying
    powergrids (for each mix) where not the same.
  • [FIXED] a bug in generate_classes (experimental_read_from_local_dir) with alert data.
  • [FIXED] a bug in the Runner when using multi processing on macos and windows OS: some non default
    parameters where not propagated in the "child" process (bug in runner._ger_params)
  • [ADDED] possibility to skip some step when calling env.reset(..., options={"init ts": ...})
  • [ADDED] possibility to limit the duration of an episode with env.reset(..., options={"max step": ...})
  • [ADDED] possibility to specify the "reset_options" used in env.reset when
    using the runner with runner.run(..., reset_options=xxx)
  • [ADDED] the argument mp_context when building the runner to help pass a multiprocessing context in the
    grid2op Runner
  • [ADDED] the time series are now able to regenerate their "random" part
    even when "cached" thanks to the addition of the regenerate_with_new_seed of the
    GridValue class (in public API)
  • [ADDED] MultifolderWithCache now supports FromHandlers time series generator
  • [IMPROVED] more consistency in the way the classes are initialized at the creation of an environment
  • [IMPROVED] more consistency when an environment is copied (some attributes of the copied env were
    deep copied incorrectly)
  • [IMPROVED] Doc about the runner
  • [IMPROVED] the documentation on the time series folder.
  • [IMPROVED] now the "maintenance from json" (eg the JSONMaintenanceHandler or the
    GridStateFromFileWithForecastsWithMaintenance) can be customized with the day
    of the week where the maintenance happens (key maintenance_day_of_week)
  • [IMPROVED] in case of "MultiMixEnvironment" there is now only class generated for
    all the underlying mixes (instead of having one class per mixes)
  • [IMPROVED] the EpisodeData have now explicitely a mode where they can be shared accross
    processes (using fork at least), see ep_data.make_serializable
  • [IMPROVED] chronix2grid tests are now done independantly on the CI
