# Qwen2.5
## 论文
无
## 模型结构
Qwen2.5是阿里云开源的最新一代大型语言模型，标志着Qwen系列在性能和功能上的又一次飞跃。本次更新着重提升了模型的多语言处理能力，支持超过29种语言，包括中文、英文、法文、西班牙文、葡萄牙文、德文等。所有规模的模型现在都能支持高达128K tokens的上下文长度，并能生成最长8K tokens的内容。预训练数据集也从7T tokens扩展到了18T tokens，显著提升了模型的知识储备。此外，Qwen2.5还增强了对系统提示的适应性，提升了角色扮演和聊天机器人的背景设置能力。模型系列包括从0.5B到72B不同参数规模的版本，以满足不同应用场景的需求 。

## 算法原理
和Qwen一样，Qwen2.5仍然是一个decoder-only的transformer模型，使用SwiGLU激活函数、RoPE、多头注意力机制等。

## 环境配置
### Docker（方法一）
提供[光源](https://www.sourcefind.cn/#/image/dcu/custom)拉取推理的docker镜像：
```
docker pull image.sourcefind.cn:5000/dcu/admin/base/pytorch:2.1.0-ubuntu20.04-dtk24.04.2-py3.10
# <Image ID>用上面拉取docker镜像的ID替换
# <Host Path>主机端路径
# <Container Path>容器映射路径
docker run -it --name qwen2.5_vllm --privileged --shm-size=64G --device=/dev/kfd --device=/dev/dri/ --cap-add=SYS_PTRACE --security-opt seccomp=unconfined --ulimit memlock=-1:-1 --ipc=host --network host --group-add video -v /opt/hyhal:/opt/hyhal -v <Host Path>:<Container Path> <Image ID> /bin/bash
```
`Tips：若在K100/Z100L上使用，使用定制镜像docker pull image.sourcefind.cn:5000/dcu/admin/base/custom:vllm0.5.0-dtk24.04.1-ubuntu20.04-py310-zk-v1,K100/Z100L不支持awq量化`
### Dockerfile（方法二）
```
# <Host Path>主机端路径
# <Container Path>容器映射路径
docker build -t qwen2.5:latest .
docker run -it --name qwen2.5_vllm --privileged --shm-size=64G --device=/dev/kfd --device=/dev/dri/ --cap-add=SYS_PTRACE --security-opt seccomp=unconfined --ulimit memlock=-1:-1 --ipc=host --network host --group-add video -v /opt/hyhal:/opt/hyhal:ro -v <Host Path>:<Container Path> qwen2.5:latest /bin/bash
```
### Anaconda（方法三）
```
conda create -n qwen2.5_vllm python=3.10
```

### 离线批量推理
```bash
python examples/offline_inference.py
```
其中，`prompts`为提示词；`temperature`为控制采样随机性的值，值越小模型生成越确定，值变高模型生成更随机，0表示贪婪采样，默认为1；`max_tokens=16`为生成长度，默认为1；
`model`为模型路径；`tensor_parallel_size=1`为使用卡数，默认为1；`dtype="float16"`为推理数据类型，如果模型权重是bfloat16,需要修改为float16推理,`quantization="gptq"`为使用gptq量化进行推理,需下载以上GPTQ模型。`quantization="awq"`为使用awq量化进行推理,需下载以上AWQ模型。
### 离线批量推理性能测试
1、指定输入输出
```bash
python benchmarks/benchmark_throughput.py --num-prompts 1 --input-len 32 --output-len 128 --model Qwen/Qwen2.5-7B-instruct -tp 1 --trust-remote-code --enforce-eager --dtype float16
```
其中 `--num-prompts`是batch数，`--input-len`是输入seqlen，`--output-len`是输出token长度，`--model`为模型路径，`-tp`为使用卡数，`dtype="float16"`为推理数据类型，如果模型权重是bfloat16,需要修改为float16推理。若指定 `--output-len 1`即为首字延迟。`-q gptq`为使用gptq量化模型进行推理。
2、使用数据集
下载数据集：
```bash
wget https://huggingface.co/datasets/anon8231489123/ShareGPT_Vicuna_unfiltered/resolve/main/ShareGPT_V3_unfiltered_cleaned_split.json
```
```bash
python benchmarks/benchmark_throughput.py --num-prompts 1 --model Qwen/Qwen2.5-7B-instruct --dataset ShareGPT_V3_unfiltered_cleaned_split.json -tp 1 --trust-remote-code --enforce-eager --dtype float16
```
其中 `--num-prompts`是batch数，`--model`为模型路径，`--dataset`为使用的数据集，`-tp`为使用卡数，`dtype="float16"`为推理数据类型，如果模型权重是bfloat16,需要修改为float16推理。`-q gptq`为使用gptq量化模型进行推理。
### OpenAI api服务推理性能测试
1.启动服务：
```bash
python -m vllm.entrypoints.openai.api_server --model Qwen/Qwen2.5-7B-instruct --enforce-eager --dtype float16 --trust-remote-code
```
2.启动客户端
```
python benchmarks/benchmark_serving.py --model Qwen/Qwen2.5-7B-instruct --dataset ShareGPT_V3_unfiltered_cleaned_split.json --num-prompts 1 --trust-remote-code
```
参数同使用数据集，离线批量推理性能测试，具体参考[benchmarks/benchmark_serving.py](/codes/modelzoo/qwen1.5_vllm/-/blob/master/benchmarks/benchmark_serving.py)
### OpenAI兼容服务
启动服务：
```bash
python -m vllm.entrypoints.openai.api_server --model Qwen/Qwen2.5-7B-instruct --enforce-eager --dtype float16 --trust-remote-code
```
这里 `--model`为加载模型路径，`--dtype`为数据类型：float16，默认情况使用tokenizer中的预定义聊天模板，`--chat-template`可以添加新模板覆盖默认模板,`-q gptq`为使用gptq量化模型进行推理,`-q awqq`为使用awq量化模型进行推理。
列出模型型号：
```bash
curl http://localhost:8000/v1/models
```
### OpenAI Completions API和vllm结合使用
```bash
curl http://localhost:8000/v1/completions \
-H "Content-Type: application/json" \
-d '{
"model": "Qwen/Qwen2.5-7B-instruct",
"prompt": "What is deep learning?",
"max_tokens": 7,
"temperature": 0
}'
```
或者使用[examples/openai_completion_client.py](examples/openai_completion_client.py)
### OpenAI Chat API和vllm结合使用
```bash
curl http://localhost:8000/v1/chat/completions \
-H "Content-Type: application/json" \
-d '{
"model": "Qwen/Qwen2.5-7B-instruct",
"messages": [
{"role": "system", "content": "What is deep learning?"},
{"role": "user", "content": "What is deep learning?"}
]
}'
```
或者使用[examples/openai_chatcompletion_client.py](examples/openai_chatcompletion_client.py)
### **gradio和vllm结合使用**
1.安装gradio
```
pip install gradio
```
2.安装必要文件
2.1 启动gradio服务，根据提示操作
```
python gradio_openai_chatbot_webserver.py --model "Qwen/Qwen2.5-7B-instruct" --model-url http://localhost:8000/v1 --temp 0.8 --stop-token-ids ""
```
2.2 更改文件权限
打开提示下载文件目录，输入以下命令给予权限
```
chmod +x frpc_linux_amd64_v0.*
```
3.启动OpenAI兼容服务
```
python -m vllm.entrypoints.openai.api_server --model Qwen/Qwen2.5-7B-instruct --enforce-eager --dtype float16 --trust-remote-code --port 8000
```
4.启动gradio服务
```
python gradio_openai_chatbot_webserver.py --model "Qwen/Qwen2.5-7B-instruct" --model-url http://localhost:8000/v1 --temp 0.8 --stop-token-ids ""
```
5.使用对话服务
在浏览器中输入本地 URL，可以使用 Gradio 提供的对话服务。

Prompt: 'What is deep learning?', Generated text: ' Deep learning is a subset of machine learning that involves the use of neural networks to model and solve complex problems. Neural networks are a network of interconnected nodes or " neurons" that are designed to recognize patterns in data, learn from examples, and make predictions or decisions.\nThe term "deep" in deep learning refers to the use of multiple layers or hidden layers in these neural networks. Each layer processes the input data in a different way, extracting increasingly abstract features as the data passes through.'
