This includes training, handling messages, loading a dialogue model, getting the next action, and handling a channel. `create_processor`( _preprocessor=None_) Instantiates a processor based on the set state of the agent. Return type: `MessageProcessor` _async_`execute_action`( _sender_id_, _action_, _output_channel_, _policy_, _confidence_) Handle a single message. Return type: [`DialogueStateTracker`](https://legacy-docs-v1.rasa.com/1.7.3/api/tracker/#rasa.core.trackers.DialogueStateTracker) `handle_channels`( _channels_, _http_port=5005_, _route='/webhooks/'_, _cors=None_) Start a webserver attaching the input channels and handling msgs. Return type: `Sanic` _async_`handle_message`( _message_, _message_preprocessor=None_, _**kwargs_) Handle a single message. Return type: `Optional`[`List`[`Dict`[`str`, `Any`]]` _async_`handle_text`( _text_message_, _message_preprocessor=None_, _output_channel=None_, _sender_id='default_) Handle a single message. If a message preprocessor is passed, the message will be passed to that function first and the return value is then used as the input for the dialogue engine. Return type: `Optional`[`List`[`Dict`[`str`, `Any`]]` `is_core_ready`() Check if all necessary components and policies are ready to use the agent. Return type: `bool` `is_ready`() Check if all necessary components are instantiated to use agent. Return type: `bool` _classmethod_`load`( _model_path_, _interpreter=None_, _generator=None_, _tracker_store=None_, _lock_store=None_, _action_endpoint=None_, _model_server=None_, _remote_storage=None_, _path_to_model_archive=None_) Load a persisted model from the passed path.

Return type: `List`[`DialogueStateTracker`](https://legacy-docs-v1.rasa.com/1.7.3/api/tracker/#rasa.core.trackers.DialogueStateTracker) _async_`log_message`( _message_, _message_preprocessor=None_, _**kwargs_) Append a message to a dialogue - does not predict actions. Return type: [`DialogueStateTracker`](https://legacy-docs-v1.rasa.com/1.7.3/api/tracker/#rasa.core.trackers.DialogueStateTracker) _async_`parse_message_using_nlu_interpreter`( _message_data_, _tracker=None_) Handles message text and intent payload input messages. Return type: `Dict`[`str`, `Any`] `persist`( _model_path_) Persists this agent into a directory for later loading and usage. Return type: `None` _async_`predict_next`( _sender_id_, _**kwargs_) Handle a single message. Return type: `Optional`[`Dict`[`str`, `Any`]] `toggle_memoization`( _activate_) Toggles the memoization on and off. Return type: `None` `train`( _training_trackers_, _**kwargs_) Train the policies / policy ensemble using dialogue data from file. Return type: `None` _async_`trigger_intent`( _intent_name_, _entities_, _output_channel_, _tracker_) Trigger a user intent, e.g. triggered by an external event. Return type: `None`
