# GLM-4V_vllm # GLM-4V
多模态视觉大模型 **GLM-4V-9B** 具备 1120 * 1120 高分辨率下的中英双语多轮对话能力，在中英文综合能力、感知推理、文字识别、图表理解等多方面多模态评测中，GLM-4V-9B 表现出超越 GPT-4-turbo-2024-04-09、Gemini 1.0 Pro、Qwen-VL-Max 和 Claude 3 Opus 的卓越性能。

## 论文
- [GLM: General Language Model Pretraining with Autoregressive Blank Infilling](https://arxiv.org/abs/2103.10360)
## 模型结构
GLM-4-9B 是智谱 AI 推出的最新一代预训练模型 GLM-4 系列中的开源版本。
<div align="center">
<img src="./images/GLM.png"/>
</div>
## 算法原理
在强化文本能力的同时，我们首次推出了基于GLM基座的开源多模态模型GLM-4V-9B。这一模型采用了与CogVLM2相似的架构设计，能够处理高达1120 x 1120分辨率的输入，并通过降采样技术有效减少了token的开销。为了减小部署与计算开销，GLM-4V-9B没有引入额外的视觉专家模块，采用了直接混合文本和图片数据的方式进行训练，在保持文本性能的同时提升多模态能力。

## 环境配置
### Docker（方法一）
[光源](https://www.sourcefind.cn/#/service-details)拉取docker镜像的地址与使用步骤
```
docker pull image.sourcefind.cn:5000/dcu/admin/base/custom:vllm0.9.2-ubuntu22.04-dtk25.04.1-rc5-rocblas104381-0915-das1.6-py3.10-20250916-rc2
# <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
# 若要在主机端和容器端映射端口需要删除--network host参数
docker run -it --name internlm_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
```
### Dockerfile（方法二）
```
# <Host Path>主机端路径
# <Container Path>容器映射路径
docker build -t internlm:latest .
docker run -it --name internlm_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> internlm:latest /bin/bash
```

> vllm serve model_path --trust-remote-code --port 8000 --host 0.0.0.0 --allowed-local-media-path xxxx --hf-overrides '{"architectures": ["GLM4VForCausalLM"]}' --chat-template examples/template_chatml.jinja
### OpenAI Completions API和vllm结合使用
```bash
curl -X POST http://localhost:8000/v1/chat/completions -H "Content-Type: application/json" -d '{
"model": "model_path",
"messages": [
{
"role": "user",
"content": [
{"type": "text", "text": "What is the content of this image？"},
{"type": "image_url", "image_url": {"url": "xxx"}}
]
}
]
}'
```
### **gradio和vllm结合使用**
1.安装gradio
```
pip install gradio
```
2.安装必要文件与端口映射
2.1 启动gradio服务，根据提示操作
```
python gradio_openai_vlm_webserver.py --model "/mnt/data/llm-models/llava/llava-1.5-7b-hf" --model-url http://localhost:8000/v1 --host "0.0.0.0" --port 8001
```
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.*
```
2.3端口映射
```
ssh -L 8000:计算节点IP:8000 -L 8001:计算节点IP:8001 用户名@登录节点 -p 登录节点端口
```
3.启动OpenAI兼容服务
`cd examples`
```
vllm serve /mnt/data/llm-models/llava/llava-1.5-7b-hf --chat-template template_llava.jinja --port 8000 --host"0.0.0.0"
```

```
python gradio_openai_vlm_webserver.py --model "/mnt/data/llm-models/llava/llava-1.5-7b-hf" --model-url http://localhost:8000/v1 --host "0.0.0.0" --port 8001"
```
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。
