一、GraphRAG安装
1.创建一个新项目
建议使用Python3.11环境
2.安装GraphRAG
python
pip install graphrag
3.初始化
python
mkdir -p ./ragtest/input
curl https://raw.githubusercontent.com/win4r/mytest/main/book.txt > ./ragtest/input/book.txt
python3 -m graphrag.index --init --root ./ragtest
4.配置相关文件
将API_KEY改成chatgpt4的api
5.执行并构建索引
python
python3 -m graphrag.index --root ./ragtest
二、Chainlit安装
1.安装Chainlit包
python
pip3 install chainlit
python
import chainlit as cl
import subprocess
import shlex
@cl.on_chat_start
def start():
cl.user_session.set("history", [])
@cl.on_message
async def main(message: cl.Message):
history = cl.user_session.get("history")
# 从 Message 对象中提取文本内容
query = message.content
# 构建命令
cmd = [
"python3", "-m", "graphrag.query",
"--root", "./ragtest",
"--method", "local",
]
# 安全地添加查询到命令中
cmd.append(shlex.quote(query))
# 运行命令并捕获输出
try:
result = subprocess.run(cmd, capture_output=True, text=True, check=True)
output = result.stdout
# 提取 "SUCCESS: Local Search Response:" 之后的内容
response = output.split("SUCCESS: Local Search Response:", 1)[-1].strip()
history.append((query, response))
cl.user_session.set("history", history)
await cl.Message(content=response).send()
except subprocess.CalledProcessError as e:
error_message = f"An error occurred: {e.stderr}"
await cl.Message(content=error_message).send()
if __name__ == "__main__":
cl.run()
3.运行
python
chainlit run app.py
