class lumen.ai.agents.SourceAgent(*, table_upload_callbacks, debug, steps_layout, user, tools, interface, memory, llm, prompts, template_overrides, conditions, exclusions, not_with, purpose, name)#

SourceAgent renders a form that allows a user to upload or provide a URI to one or more datasets.

Parameters#

table_upload_callbacks

type: dict
default: {}
Dictionary mapping from file extensions to callback function,e.g. {“hdf5”: …}. The callback function should accept the file bytes andtable alias, add or modify the source in memory, and return a bool(True if the table was successfully uploaded).

Methods#

async SourceAgent.requirements(messages: list[Message]) → list[str]#
async SourceAgent.respond(messages: list[Message], render_output: bool = False, step_title: str | None = None) → Any#

Provides a response to the user query.

The type of the response may be a simple string or an object.

Parameters:

  • messages (list[Message]) – The list of messages corresponding to the user query and any other system messages to be included.

  • render_output (bool) – Whether to render the output to the chat interface.

  • step_title (str | None) – If the Agent response is part of a longer query this describes the step currently being processed.

SourceAgent.servable(title: str | None = None, location: bool | Location = True, area: str = 'main', target: str | None = None) → Viewable#

Serves the object or adds it to the configured pn.state.template if in a panel serve context, writes to the DOM if in a pyodide context and returns the Panel object to allow it to display itself in a notebook context.

Parameters:

  • title (str) – A string title to give the Document (if served as an app)

  • location (boolean or panel.io.location.Location) – Whether to create a Location component to observe and set the URL location.

  • area (str (deprecated)) – The area of a template to add the component too. Only has an effect if pn.config.template has been set.

  • target (str) – Target area to write to. If a template has been configured on pn.config.template this refers to the target area in the template while in pyodide this refers to the ID of the DOM node to write to.

Return type:

The Panel object itself

SourceAgent.show(title: str | None = None, port: int = 0, address: str | None = None, websocket_origin: str | None = None, threaded: bool = False, verbose: bool = True, open: bool = True, location: bool | Location = True, **kwargs) → threading.Thread | Server#

Starts a Bokeh server and displays the Viewable in a new tab.

Parameters:

  • title (str | None) – A string title to give the Document (if served as an app)

  • port (int (optional, default=0)) – Allows specifying a specific port

  • address (str) – The address the server should listen on for HTTP requests.

  • websocket_origin (str or list(str) (optional)) – A list of hosts that can connect to the websocket. This is typically required when embedding a server app in an external web site. If None, “localhost” is used.

  • threaded (boolean (optional, default=False)) – Whether to launch the Server on a separate thread, allowing interactive use.

  • verbose (boolean (optional, default=True)) – Whether to print the address and port

  • open (boolean (optional, default=True)) – Whether to open the server in a new browser tab

  • location (boolean or panel.io.location.Location) – Whether to create a Location component to observe and set the URL location.

Returns:

server – Returns the Bokeh server instance or the thread the server was launched on (if threaded=True)

Return type:

bokeh.server.Server or panel.io.server.StoppableThread
