+# 增量预训练教程
+
+# 增量预训练简介
+增量预训练旨在提升模型在特定领域或任务的能力。
+
+
+# 预训练流程
+- Step1 处理数据
+- Step2 配置config（全量、Lora、Qlora）
+- Step3 启动训练（单卡、多卡、是否使用deepspeed）
+- Step4 模型合成
+- Step5 模型测试
+- Step6 模型上传
+
+# EmoLLM增量预训练教程
+基于微调中的数据集[datasets](../../datasets)修改而来
+
+- Step1 修改`ft2pt.py`中的文件路径
+这里以[output2.json](../../datasets/processed/output2.json)为例，运行脚本生成[pt.json](../../datasets/pt/pt.json)
+
+- Step2 [config](./internlm2_chat_1_8b_qlora_e3_pt.py)
+注意：本config采用了**变长注意力 (Variable Length Attention)**
+需要安装flash_attn
+`MAX_JOBS=4 pip install flash-attn --no-build-isolation`
+
+
+- Step3 训练：
+```
+# On a single GPU
+xtuner train internlm2_chat_1_8b_qlora_e3_pt.py --deepspeed deepspeed_zero2
+# On multiple GPUs
+(DIST) NPROC_PER_NODE=${GPU_NUM} xtuner train internlm2_chat_1_8b_qlora_e3_pt.py --deepspeed deepspeed_zero2
+(SLURM) srun ${SRUN_ARGS} xtuner train internlm2_chat_1_8b_qlora_e3_pt.py --launcher slurm --deepspeed deepspeed_zero2
+```
+
+- 其余流程请参考[微调教程](../../xtuner_config/README.md)
