服务器：800TA2
芯片：910B3
模型：Qwen2.5-14B-Instruct
数据集：魔搭自定义数据集，alpaca格式

1. 使用docker安装

1.1 配置docker

配置docker镜像源：

sudo vi /etc/docker/daemon.json

填入：

{"registry-mirrors": ["https://2t697950.mirror.aliyuncs.com","https://docker.1ms.run","https://docker.xuanyuan.me"]
}

安装 docker-compose

sudo curl -L https://github.com/docker/compose/releases/download/v2.33.0/docker-compose-linux-aarch64 -o /usr/local/bin/docker-compose
chmod 777 /usr/local/bin/docker-compose
docker-compose -v

1. 2 拉取 LLaMA-Factory

# 以下环境都基于路径  /home/aicc1
mkdir  /home/aicc1
cd  /home/aicc1
git clone https://github.com/hiyouga/LLaMA-Factory.git
cd LLaMA-Factory/docker/docker-npu

1.3 修改配置

请保证docker镜像源已配置完毕。
修改Dockerfile 、 docker-compose.yml，中挂载的设备数量、python镜像源。
默认只挂载了一个卡，下面的配置通过添加devices挂载了8张卡。

挂载了目录 /home/aicc1，用于与宿主机数据交互。具体请修改为你自己的文件路径

docker-compose.yml：

2. 下载模型

ps：请修改为你要训练的模型

# 进入容器
docker exec -it llamafactory bash
# 下载模型
pip install modelscope
modelscope download --model Qwen/Qwen2.5-14B-Instruct --local_dir /home/aicc1/Qwen2.5-14B-Instruct/

3. 准备训练数据

3.1 下载数据集

使用魔搭上一个医疗的数据，大小：580M，格式：Alpaca。
数据处理或格式要求请查看官方文档：
传送门

ps：如果认为数据集太大（训练时间会加长），可以下载后删除大部分，保留几百条数据去测试

# 在宿主机上 （容器中没有下载wget）
cd /home/aicc1/LLaMA-Factory/data
wget https://modelscope.cn/datasets/swift/Alpaca-CoT/resolve/master/Chinese-medical/chinesemedical.json

3.2 自定义数据集配置

如果使用自定义数据集，需要配置LLaMA-Factory

vim /home/aicc1/LLaMA-Factory/data/dataset_info.json

在其中添加：

"my_dataset": {"file_name": "chinesemedical.json","columns": {"prompt": "instruction","query": "input","response": "output"}
},

4. 训练

4.1 训练配置

mkdir /home/aicc1/LLaMA-Factory/qwen_config
cd /home/aicc1/LLaMA-Factory/qwen_config
tourch qwen2_5_lora_sft_ds.yaml

qwen2_5_lora_sft_ds.yaml 配置：

该配置采用文档中qwen1.5的训练配置。传送门

请注意一些关键参数：
model_name_or_path：下载的模型路径
dataset：数据集
num_train_epochs：训练轮次

本篇用到的数据集为 LLaMA-Factory 自带的 identity 和 自定义的my_dataset，对 identity 数据集进行如下全局替换即可实现定制指令：
{{name}} 替换为 Ascend-helper
{{author}} 替换为 Ascend

执行下方命令替换：

sed -i 's/{{name}}/Ascend-helper/g; s/{{author}}/Ascend/g' /home/aicc1/LLaMA-Factorydata/identity.json

4.2 启动训练

cd /home/aicc1/LLaMA-Factory
ASCEND_RT_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 torchrun --nproc_per_node 8 \--nnodes 1 \--node_rank 0 \--master_addr 127.0.0.1 \--master_port 7007 \src/train.py qwen_config/qwen2_5_lora_sft_ds.yaml

训练开始：

训练中间：

训练结束：

输出关于训练、评估的指标信息

结果保存在saves文件夹下

Loss下降的感觉还不错：

4.3 训练效果测试

指定原始模型路径、训练后lora路径。

llamafactory-cli chat --model_name_or_path /home/aicc1/Qwen2.5-14B-Instruct \--adapter_name_or_path /home/aicc1/LLaMA-Factory/saves/Qwen2.5-14B/lora/sft \--template qwen \--finetuning_type lora

询问identity数据集内容，返回成功。如图所示：

5. 合并权重
