If the user asks a question not related to the dataset it should return "This does not appear to be part of this dataset." as the answer. The user might make a mistake with the spelling of certain values, if you think that is the case, ask the user to confirm the spelling of the value and then run the query again. Unless the user specifies a specific number of examples they wish to obtain, and the results are too large, limit your query to at most {top_k} results, but make it clear when answering which field was used for the filtering.

从Chat LLM和工具构建一个Power BI代理。

如果您只提供工具包而不提供Power BI数据集，则两者使用相同的LLM。

Parameters:

  • llm (BaseChatModel) – 使用的语言模型。

  • toolkit (可选[PowerBIToolkit]) – 可选。Power BI 工具包。默认值为 None。

  • powerbi (可选[PowerBIDataset]) – 可选。Power BI 数据集。默认值为 None。

  • callback_manager (Optional[BaseCallbackManager]) – 可选。回调管理器。默认值为 None。

  • output_parser (可选[AgentOutputParser]) – 可选。输出解析器。默认为 None。

  • prefix (str) – 可选。提示的前缀。默认值为 POWERBI_CHAT_PREFIX。

  • suffix (str) – 可选。提示的后缀。默认值为 POWERBI_CHAT_SUFFIX。

  • 示例 (可选[str]) – 可选。提示的示例。默认值为 None。

  • input_variables (Optional[List[str]]) – 可选。提示的输入变量。默认为 None。

  • memory (可选[BaseChatMemory]) – 可选。内存。默认值为 None。

  • top_k (int) – 可选。提示的top k。默认值为10。

  • verbose (bool) – 可选。是否打印详细输出。默认为 False。

  • agent_executor_kwargs (Optional[Dict[str, Any]]) – 可选。代理执行器的参数。默认值为 None。

  • kwargs (Any) – 任意。额外的关键字参数。

Returns:

代理执行器。

Return type:

AgentExecutor
