        Note that this should only be used in the `__call__` method of the processors with special
        arguments. Special arguments are arguments that aren't `text`, `images`, `audio`, nor `videos`
        but also aren't passed to the tokenizer, image processor, etc. Examples of such processors are:
            - `CLIPSegProcessor`

        Also note that passing by position to the processor call is now deprecated and will be disallowed
        in future versions. We only have this for backward compatibility.

            Suppose that the processor class has `optional_call_args = ["arg_name_1", "arg_name_2"]`.

            processor("What is common in these images?", images, arg_value_1, arg_value_2)
            ```

            Then, this method will return:
