Computes an action for the specified policy on the local Worker.
Note that you can also access the policy object through self.get_policy(policy_id) and call compute_actions() on it directly.
observation – Observation from the environment.
state – RNN hidden state, if any. If state is not None, then all of compute_single_action(…) is returned (computed action, rnn state(s), logits dictionary). Otherwise compute_single_action(…) is returned (computed action).
prev_action – Previous action value, if any.
prev_reward – Previous reward, if any.
info – Env info dict, if any.
policy_id – Policy to query (only applies to multi-agent).
full_fetch – Whether to return extra action fetch results. This is always set to True if RNN state is specified.
explore – Whether to pick an exploitation or exploration action (default: None -> use self.config.explore).
timestep – The current (sampling) time step.
episodes – This provides access to all of the internal episodes’ state, which may be useful for model-based or multi-agent algorithms.
unsquash_actions – Should actions be unsquashed according to the env’s/Policy’s action space? If None, use self.config.normalize_actions.
clip_actions – Should actions be clipped according to the env’s/Policy’s action space? If None, use self.config.clip_actions.
- Keyword Arguments
kwargs – forward compatibility placeholder
The computed action if full_fetch=False, or a tuple consisting of the full output of policy.compute_actions_from_input_dict() if full_fetch=True or we have an RNN-based Policy.
