I am using huggingface transformer API and meta-llama/Llama-2-7b-chat-hf model to generate responses in an A100. I find out that it can generate response when the prompt is short, but it fails to generate a response when the prompt is long. The max_length is 4096 for meta-llama/Llama...

具体来说,首先使用LLAMA 2-Chat中使用的RLHF数据集,并用LLAMA 2-Chat本身生成的自指导(self-instruct)长数据对其进行扩充,预期模型能够通过大量RLHF数据学习到一系列不同的技能,并通过自指导数据将知识转移到长上下文的场景中。 数据生成过程侧重于QA格式的任务:从预训练语料库中的长文档开始,随机选择一个文本块,...
