When I make the above change in utils.rllib.py file, following errors pop up next time I try to run the pre-trained model.

(RolloutWorker pid=18989) In order to fix this problem, do the following:
(RolloutWorker pid=18989)
(RolloutWorker pid=18989) 1) Run pip install gymnasium on your command line.
(RolloutWorker pid=18989) 2) Change all your import statements in your code from
(RolloutWorker pid=18989) import gym -> import gymnasium as gym OR
(RolloutWorker pid=18989) from gym.space import Discrete -> from gymnasium.spaces import Discrete
(RolloutWorker pid=18989)
(RolloutWorker pid=18989) For your custom (single agent) gym.Env classes:
(RolloutWorker pid=18989) 3.1) Either wrap your old Env class via the provided from gymnasium.wrappers import (RolloutWorker pid=18989) EnvCompatibility wrapper class.
(RolloutWorker pid=18989) 3.2) Alternatively to 3.1:
(RolloutWorker pid=18989) - Change your reset() method to have the call signature 'def reset(self, *,
(RolloutWorker pid=18989) seed=None, options=None)'
(RolloutWorker pid=18989) - Return an additional info dict (empty dict should be fine) from your reset()
(RolloutWorker pid=18989) method.
(RolloutWorker pid=18989) - Return an additional truncated flag from your step() method (between done and
(RolloutWorker pid=18989) info). This flag should indicate, whether the episode was terminated prematurely
(RolloutWorker pid=18989) due to some time constraint or other kind of horizon setting.
(RolloutWorker pid=18989)
(RolloutWorker pid=18989) For your custom RLlib MultiAgentEnv classes:
(RolloutWorker pid=18989) 4.1) Either wrap your old MultiAgentEnv via the provided
(RolloutWorker pid=18989) from ray.rllib.env.wrappers.multi_agent_env_compatibility import (RolloutWorker pid=18989) MultiAgentEnvCompatibility wrapper class.
(RolloutWorker pid=18989) 4.2) Alternatively to 4.1:
(RolloutWorker pid=18989) - Change your reset() method to have the call signature
(RolloutWorker pid=18989) 'def reset(self, *, seed=None, options=None)'
(RolloutWorker pid=18989) - Return an additional per-agent info dict (empty dict should be fine) from your
(RolloutWorker pid=18989) reset() method.
(RolloutWorker pid=18989) - Rename dones into terminateds and only set this to True, if the episode is really
(RolloutWorker pid=18989) done (as opposed to has been terminated prematurely due to some horizon/time-limit
(RolloutWorker pid=18989) setting).
(RolloutWorker pid=18989) - Return an additional truncateds per-agent dictionary flag from your step()
(RolloutWorker pid=18989) method, including the __all__ key (100% analogous to your dones/terminateds
(RolloutWorker pid=18989) per-agent dict).
(RolloutWorker pid=18989) Return this new truncateds dict between dones/terminateds and infos. This
(RolloutWorker pid=18989) flag should indicate, whether the episode (for some agent or all agents) was
(RolloutWorker pid=18989) terminated prematurely due to some time constraint or other kind of horizon setting.

  • Return an additional info dict (empty dict should be fine) from your reset()
    method.
  • Return an additional truncated flag from your step() method (between done and

    due to some time constraint or other kind of horizon setting.

    Return this new truncateds dict between dones/terminateds and infos. This
