+## 📰 Chapter 5 Deepspeed-Chat SFT 实践 📰
+
+### 🐼 环境安装
+
+```bash
+pip install deepspeed>=0.9.0
+
+pip install -r requirements.txt
+pip install -e .
+```
+
+### 🐼 数据预处理
+
+在数据处理代码文件`dschat/utils/data/raw_datasets.py`及`dschat/utils/data/data_utils.py`(新版代码路径与教材中有所不同)中增加对新增数据的处理。
+
+### 🐼 自定义模型
+虽然 Deepspeed-Chat 内置了在各项评估上都表现良好的 Llama-2 7B 模型，但是由于模型在 预训练中并没有在足够的中文数据上训练，因此其中文能力并不强。当需要使用支持中文的预训练 模型，或者更换其他模型时，就需要对 Deepspeed-Chat 进行相应的更改来适配其他自定义的模型。对`training/step1_supervised_finetuning/main.py`进行修改来导入相应的模型并在`training/step1_supervised_finetuning/training_scripts`修改对应训练脚本。
+
+
+### 🐼 模型训练
+  ```bash
+ # 在路径 training/step1_supervised_finetuning 下运行, 示例中在一台 8 卡 Nvidia A100 机器下进行训练 
+ CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 bash training/step1_supervised_finetuning/training_scripts/baichuan/run_baichuan_7b.sh
+   ```
