请问一下运行retrieval_function_call的时候报错是什么原因

[Huanghongli]

pydantic.errors.PydanticSchemaGenerationError: Unable to generate pydantic-core schema for <class 'pandas.core.frame.DataFrame'>. Set arbitrary_types_allowed=True in the model_config to ignore this error or implement __get_pydantic_core_schema__ on your type to fully support it.

If you got this error by calling handler() within __get_pydantic_core_schema__ then you likely need to call handler.generate_schema(<some type>) since we do not call __get_pydantic_core_schema__ on <some type> otherwise to avoid infinite recursion.

在配置完环境之后运行demo报出如上错误
