Functions

build_prompt_from_template

build_prompt_from_template(
    template: str,
    llm_settings: LLMSettings,
    mapper_to_str_kwargs: Dict[str, Any] | None = None,
    output_parser: BaseOutputParser | None = None,
) -> Tuple[PromptTemplate, RunnableSerializable | None]

Additional keyword arguments for the mapper’s to_str method. Defaults to None.
output_parser (BaseOutputParser | None, default: None ) –

The output parser to be used. Defaults to None.

Returns:

Tuple[PromptTemplate, RunnableSerializable | None] –

Tuple[PromptTemplate, RunnableSerializable]: A tuple containing the prompt template and the derived output parser.
