I am using a `Seq2SeqTrainer` for evaluating a translation task. I found that the `Seq2SeqTrainingArguments` accept the `generation_num_beams` argument and several other arguments for generation. Meanwhile, it has the `generation_config` argument, which can config the `num_beams` too. So I wonder what are the difference between these arguments, will one setting in `Seq2SeqTrainingArguments` override the counterpart setting in `generation_config`?
