Fix gradio error when run demo.

[zhanluxianshen]

before is:

pydantic.errors.PydanticSchemaGenerationError: 
Unable to generate pydantic-core schema for <class 'starlette.requests.Request'>. 
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

After upgrade pip's requirments
its ok.

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.
