                  Custom logits processors that complement the default logits processors built from arguments and a

                  config an error is thrown. This feature is intended for advanced users.

                 Whether to renormalize the logits after applying all the logits processors or warpers (including the
                 custom ones). It's highly recommended to set this flag to `True` as the search algorithms suppose the
                 score logits are normalized but some logit processors or warpers break the normalization.
