description: 接入 bge-rerank 重排模型
---
## 不同模型推荐配置
推荐配置如下:
| 模型名 | 内存 | 显存 | 硬盘空间 | 启动命令 |
|------|---------|---------|----------|--------------------------|
| bge-reranker-base | >=4GB | >=4GB | >=8GB | python app.py |
| bge-reranker-large | >=8GB | >=8GB | >=8GB | python app.py |
| bge-reranker-v2-m3 | >=8GB | >=8GB | >=8GB | python app.py |
## 源码部署
### 1. 安装环境
- Python 3.9, 3.10
- CUDA 11.7
- 科学上网环境
### 2. 下载代码
3 个模型代码分别为:
1. [https://github.com/labring/FastGPT/tree/main/plugins/model/rerank-bge/bge-reranker-base](https://github.com/labring/FastGPT/tree/main/plugins/model/rerank-bge/bge-reranker-base)
2. [https://github.com/labring/FastGPT/tree/main/plugins/model/rerank-bge/bge-reranker-large](https://github.com/labring/FastGPT/tree/main/plugins/model/rerank-bge/bge-reranker-large)
3. [https://github.com/labring/FastGPT/tree/main/plugins/model/rerank-bge/bge-reranker-v2-m3](https://github.com/labring/FastGPT/tree/main/plugins/model/rerank-bge/bge-reranker-v2-m3)
### 3. 安装依赖
```sh
pip install -r requirements.txt
```
### 4. 下载模型
3个模型的 huggingface 仓库地址如下:
1. [https://huggingface.co/BAAI/bge-reranker-base](https://huggingface.co/BAAI/bge-reranker-base)
2. [https://huggingface.co/BAAI/bge-reranker-large](https://huggingface.co/BAAI/bge-reranker-large)
3. [https://huggingface.co/BAAI/bge-reranker-v2-m3](https://huggingface.co/BAAI/bge-reranker-v2-m3)
在对应代码目录下 clone 模型。目录结构:
```
bge-reranker-base/
app.py
Dockerfile
requirements.txt
```
### 5. 运行代码
```bash
python app.py
```
启动成功后应该会显示如下地址:

> 这里的 `http://0.0.0.0:6006` 就是连接地址。
## docker 部署
**镜像名分别为:**
1. registry.cn-hangzhou.aliyuncs.com/fastgpt/bge-rerank-base:v0.1 (4 GB+)
2. registry.cn-hangzhou.aliyuncs.com/fastgpt/bge-rerank-large:v0.1 (5 GB+)
3. registry.cn-hangzhou.aliyuncs.com/fastgpt/bge-rerank-v2-m3:v0.1 (5 GB+)
**端口**
6006
**环境变量**
```
ACCESS_TOKEN=访问安全凭证请求时Authorization: Bearer ${ACCESS_TOKEN}
```
**运行命令示例**
```sh
# auth token 为mytoken
docker run -d --name reranker -p 6006:6006 -e ACCESS_TOKEN=mytoken --gpus all registry.cn-hangzhou.aliyuncs.com/fastgpt/bge-rerank-base:v0.1
```
**docker-compose.yml示例**
```
version: "3"
services:
reranker:
image: registry.cn-hangzhou.aliyuncs.com/fastgpt/bge-rerank-base:v0.1
container_name: reranker
# GPU运行环境如果宿主机未安装将deploy配置隐藏即可
deploy:
resources:
reservations:
devices:
- driver: nvidia
count: all
capabilities: [gpu]
ports:
- 6006:6006
environment:
- ACCESS_TOKEN=mytoken
```
## 接入 FastGPT
1. 打开 FastGPT 模型配置,新增一个重排模型。
2. 填写模型配置表单:模型 ID 为`bge-reranker-base`,地址填写`{{host}}/v1/rerank`host 为你部署的域名/IP:Port。

## QA
### 403报错
FastGPT中自定义请求 Token 和环境变量的 ACCESS_TOKEN 不一致。
### Docker 运行提示 `Bus error (core dumped)`
尝试增加 `docker-compose.yml` 配置项 `shm_size` ,以增加容器中的共享内存目录大小。
```
...
services:
reranker:
...
container_name: reranker
shm_size: '2gb'
...
```
