# sglang 使用说明
|
||||
|
||||
## 简介
|
||||
SGLang 是一个用于大语言模型(LLM)和多模态视觉语言模型(VLM)的快速推理与服务框架。它通过后端运行时与前端语言的协同设计,与模型的交互更加高效、可控。

## 编译环境准备
|
||||
|
||||
下载光源的镜像,启动 docker:
|
||||
|
||||
```bash
|
||||
docker pull image.sourcefind.cn:5000/dcu/admin/base/vllm:0.9.2-ubuntu22.04-dtk25.04.1-rc5-rocblas101839-0811-das1.6-py3.10-20250812-beta
|
||||
|
||||
# <Image ID> 用上面拉取的 docker 镜像 ID 替换
|
||||
# <Host Path> 主机端路径
|
||||
# <Container Path> 容器映射路径
|
||||
docker run -it --name mydocker --shm-size=1024G -v /opt/hyhal:/opt/hyhal:ro --device=/dev/kfd --device=/dev/dri/ --cap-add=SYS_PTRACE <Image ID> /bin/bash
|
||||
```
|
||||
|
||||
> **注意:**
|
||||
> 1. `docker run -v /opt/hyhal:/opt/hyhal` 这个参数不能少。
|
||||
> 2. 若使用 `pip install` 下载较慢,可添加国内源,例如:
|
||||
> `-i https://pypi.tuna.tsinghua.edu.cn/simple/`
|
||||
