ray.rllib.env.multi_agent_episode.MultiAgentEpisode.is_done

property MultiAgentEpisode.is_done

Whether the episode is actually done (terminated or truncated).

A done episode cannot be continued via self.add_env_step() or being concatenated on its right-side with another episode chunk or being succeeded via self.cut().

Note that in a multi-agent environment this does not necessarily correspond to single agents having terminated or being truncated.

self.is_terminated should be True, if all agents are terminated and self.is_truncated should be True, if all agents are truncated. If only one or more (but not all!) agents are terminated/truncated the `MultiAgentEpisode.is_terminated/is_truncated should be False. This information about single agent’s terminated/truncated states can always be retrieved from the SingleAgentEpisode`s inside the 'MultiAgentEpisode one.

If all agents are either terminated or truncated, but in a mixed fashion, i.e. some are terminated and others are truncated: This is currently undefined and could potentially be a problem (if a user really implemented such a multi-agent env that behaves this way).

Returns:

Boolean defining if an episode has either terminated or truncated.
