The Agent class provides a convenient interface for the most important Rasa functionality.

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/1.10.18/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 messages.

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.

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 the 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: [`Agent`](https://legacy-docs-v1.rasa.com/1.10.18/api/agent/#rasa.core.agent.Agent)

_async_ `load_data`( _training_resource_, _remove_duplicates=True_, _unique_last_num_states=None_, _augmentation_factor=50_, _tracker_limit=None_, _use_story_concatenation=True_, _debug_plots=False_, _exclusion_percentage=None_)

Load training data from a resource.

Return type: `List`[ `DialogueStateTracker`](https://legacy-docs-v1.rasa.com/1.10.18/api/tracker/#rasa.core.trackers.DialogueStateTracker)

_async_ `log_message`( _message_, _message_preprocessor=None_, _**kwargs_)
