与微调的block_size参数有关,2048已够长了。如果需要更长的回答,可传入历史多轮对话

但是,用decode超过2048就会乱生成,没检测到结束符就会一直生成,直接内存就爆了。
有达到最大长度自动停止的配置吗?

您说的传入历史是指将上一步没生成完的输出当做输入再送一遍吗?

有可能没有结束符,这个也没什么好办法,将上次输入、输出放到history入参里,本次提示词用“继续”,这个例子是用Llama-2-7b-chat微调,效果一般。后来我在原始模型上微调过一次,效果比这个好一些。https://github.com/git-cloner/Llama2-chinese

个人理解,history的长度也算在2048内,他只是拼接到当前的输入前面了。如果上一步超了,下一步也生成不出来吧
