# 昇腾910架构基于mindformers推理Qwen-7B-Chat模型
|
|
|
|
|
|
|
|
|
|
|
|
## 环境要求
|
|
|
|
|
|
|
|
|
|
|
|
- 硬件：Ascend 910A/B
|
|
|
|
|
|
|
|
|
|
|
|
## 运行步骤
|
|
|
|
|
|
|
|
|
|
|
|
首先参考Qwen README下载官方模型到`/path/to/Qwen-7B-Chat`。
|
|
|
|
|
|
|
|
|
|
|
|
### 下载并启动镜像
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
docker pull qwenllm/qwen-mindspore:latest
|
|
|
|
|
|
|
|
|
|
|
|
cd /path/to/Qwen/ascend-support
|
|
|
|
|
|
|
|
|
|
|
|
# 下载模型到此处
|
|
|
|
|
|
CHECKPOINT_PATH=/path/to/Qwen-7B-Chat
|
|
|
|
|
|
|
|
|
|
|
|
cd ascend-support
|
|
|
|
|
|
|
|
|
|
|
|
# 启动docker容器
|
|
|
|
|
|
bash docker_qwen.sh -c ${CHECKPOINT_PATH}
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
### 执行权重转换
|
|
|
|
|
|
|
|
|
|
|
|
在容器内执行下面的命令，将Qwen模型转换为适配`mindformers`的格式：
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
python3 /data/qwen/mindformers/research/qwen/convert_weight.py
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
转换后模型的输出位置为`${CHECKPOINT_PATH}/qwen-7b-chat.ckpt`。
|
|
|
|
|
|
|
|
|
|
|
|
### 执行推理
|
|
|
|
|
|
|
|
|
|
|
|
在容器内执行下面的命令，进行推理：
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
cd /data/qwen/mindformers/research/qwen
|
|
|
|
|
|
export PYTHONPATH=/data/qwen/mindformers:$PYTHONPATH
|
|
|
|
|
|
python3 infer_qwen.py
|
|
|
|
|
|
```
|
