     This method can be used with a customizable decoding function as long as it
     follows the signature of `DecodeFnCallable`. In order to provide a unified

     beam size is a concept unique to beam search. Conceptually, it corresponds
     to the number of sequences returned by the beam search.  Therefore, the
     generic argument `num_decodes` corresponds to the beam size if
