Methods

aevaluate_agent_trajectory(*, prediction, ...)

Asynchronously evaluate a trajectory.

evaluate_agent_trajectory(*, prediction, ...)

Evaluate a trajectory.
async aevaluate_agent_trajectory(*, prediction: str, agent_trajectory: Sequence[Tuple[AgentAction, str]], input: str, reference: str | None = None, **kwargs: Any) → dict[source]#

  • input (str) – The input to the agent.

  • reference (Optional[str]) – The reference answer.

  • kwargs (Any)

Returns:

The evaluation result.

Return type:

dict
