支持的训练方法(这里的Pre-Training指的是增量预训练)
LlamaFactory基于PEFT和TRL进行二次封装,从而可以快速开始SFT和RLHF微调。同时,引入GaLore和Unsloth等方案,能降低训练显存占用。
•各种模型: LLaMA, LLaVA, Mistral, Mixtral-MoE, Qwen, Yi, Gemma, Baichuan, ChatGLM, Phi, etc.
•集成训练方法: (Continuous) pre-training, (multimodal) supervised fine-tuning, reward modeling, PPO, DPO and ORPO.
•Scalable resources: 32-bit full-tuning, 16-bit freeze-tuning, 16-bit LoRA and 2/4/8-bit QLoRA via AQLM/AWQ/GPTQ/LLM.int8.
•Advanced algorithms: GaLore, BAdam, DoRA, LongLoRA, LLaMA Pro, Mixture-of-Depths, LoRA+, LoftQ and Agent tuning.
•实用tricks: FlashAttention-2, Unsloth, RoPE scaling, NEFTune and rsLoRA.
•实验监控

估计的不一定准,取决于输入输出长度、batch_size。建议使用accelerate估计。
•examples目录下,存放各种预置的例子
•src目录的llm-tuner是项目源码
•data目录下,存放各种预置的数据集,以及数据集配置文件dataset_info.json
可以在 src/llmtuner/data/template.py 中添加自己的对话模板。
为了确保和LLM SFT时一致,确保对话模板格式很关键。
关于数据集文件的格式,请参考data/README_zh.md[92]的内容。你可以使用 HuggingFace / ModelScope 上的数据集或加载本地数据集。
使用自定义数据集时,请更新data/dataset_info.json[93]文件,进行数据集名称、数据集字段以及数据集路径的配置。

目前,最新版本绝大多数examples已改成yaml配置文件,而不是shell命令用parser读取参数了.
当然,本质上就是把训练参数传到train.py中

src/train.pyexamples/lora_multi_gpu/llama3_lora_sft.yaml之前一个训练日志:
配置了几个数据集,进行单机多卡 llama3_8b_instruct进行中文数据集sft训练
llama3_8b_instruct进行增量预训练还是中文数据SFT都不过是倒腾数据集和配置脚本的事情,当然这只是踏出训练的第一步。
毕竟搞出一个baseline和能训练好还是两码事(需要自己调参摸索,更需要学习开源的经验)。
LlamaFactory适合快速进行全参数、LoRA等高效微调,适合增量预训练、指令微调和强化学习微调。
它具备可视化界面,同时集成了多种比较前沿的训练Trick,用的人多。
但是呢,由于集成地太好,隐藏了很多细节,一方面不利于学习和定制化。另一方面,在使用的时候,也需要详细了解参数配置。
LlamaFactory适合快速上手,毕竟它已经集成好的框架将分散的包组合到一起,能够省时省力,但用好需花一点精力。
