Confusion about how to pass in state to the client

[freddyaboulton]

Describe the bug

When trying to use this whisper space via the client, I got an error when supplying a value for the state in my call to predict.

I instantiated the client like this

import gradio_client as grc
client = grc.Client("abidlabs/whisper-large-v2")

view_api() told me I had to pass in a state component

Client.predict() Usage Info
---------------------------
Named API endpoints: 1

 - predict(microphone, state, api_name="/predict") -> (output_0, state)
    Parameters:
     - [Audio] microphone: str (filepath or URL to file)
     - [State] state: Any ()
    Returns:
     - [Textbox] output_0: str (string value)
     - [State] state: Any ()

But then that lead to an error

client.predict("/Users/freddy/sources/gradio/demo/same-person-or-different/samples/heath_ledger.mp3",
                         " ",
                        api_name="/predict")

    596             if self.client.serialize:

--> 725         assert len(data) == len(
    726             self.serializers
    727         ), f"Expected {len(self.serializers)} arguments, got {len(data)}"

AssertionError: Expected 2 arguments, got 3

removing the second argument (the state) fixes the error

If the state is not expected to be passed in - then maybe we should remove it from the view_api?

Is there an existing issue for this?

Also the state is omitted from the output as well
