Description

新增predict函数

• 重写_override_hp()，这样不再虚假加上TrainingArguments等类似前缀，比如同时有prompt模型和微调模型的话，override_hp就要定义一个"TrainingArguments.max_steps": 5 和 "PromptTuningArguments.max_steps"
• 新增predict函数，修改evaluate函数，与trainer对齐
• prompttrainer evaluate函数未与trainer对齐，重写了get_eval_dataloader
  -将数据预处理函数单独抽出来

@LemonNoel review一下prompt的修改有什么问题

[LemonNoel]

同一程序中多次调用 evaluate 可能有问题，需要验证一下 do_eval=True 的情况。

[lugimzzz]

实际验证加检查trainer内部代码，没有问题。目前prompt trainer暂时不支持eval_dataset为字典（也即传入多个eval_dataset）的场景，所以暂时不影响代码，如果之后支持eval_dataset为字典，需要同步修改get_eval_dataloader的逻辑。
