1.目的

利用SiliconCloud提供的免费Intern2.5-7B-Chat的API部署MindSearch。

2.过程

2.1 在GitHub上打开codespace主页

我们首先在GitHub上打开codespace，选择blank template。

然后打开一个Web端的vscode，将MindSearch进行clone

mkdir -p /workspaces/mindsearch
cd /workspaces/mindsearch
git clone https://github.com/InternLM/MindSearch.git
cd MindSearch && git checkout b832275 && cd ..

2.2 安装依赖

# 创建环境
conda create -n mindsearch python=3.10 -y
# 激活环境
conda activate mindsearch
# 安装依赖
pip install -r /workspaces/mindsearch/MindSearch/requirements.txt

2.3 获取SiliconFlow的Key

网址： https://cloud.siliconflow.cn/account/ak

2.4 启动后台MindSearch

SiliconFlow的key相关配置已经集成在了MindSearch中，直接python -m mindsearch.app 启动即可

export SILICON_API_KEY=第二步中复制的密钥
conda activate mindsearch
cd /workspaces/mindsearch/MindSearch
# -m：启动mindsearch模块下的app模块下的main方法
python -m mindsearch.app --lang cn --model_format internlm_silicon --search_engine DuckDuckGoSearch

2.5 启动MindSearch的前端

conda activate mindsearch
cd /workspaces/mindsearch/MindSearch
python frontend/mindsearch_gradio.py

2.6部署到hugging face

打开 https://huggingface.co/spaces ，然后创建自己的空间Space，选择完Gradio采用空模板后。在Settings中创建一个新的Secret并添加SiliconFlow的免费API Key。最后创建一个新目录，将原来MindSearch下的文件放在新目录下，并以app.py作为程序入口。

# 创建新目录
mkdir -p /root/mindsearch/mindsearch_deploy
# 准备复制文件
cd /root/mindsearch
cp -r /root/mindsearch/MindSearch/mindsearch /root/mindsearch/mindsearch_deploy
cp /root/mindsearch/MindSearch/requirements.txt /root/mindsearch/mindsearch_deploy
# 创建 app.py 作为程序入口
touch /root/mindsearch/mindsearch_deploy/app.py

app.py内容如下：

import json
import os

import gradio as gr
import requests
from lagent.schema import AgentStatusCode

os.system("python -m mindsearch.app --lang cn --model_format internlm_silicon &")
