新特性

1、DB-GPT 社区和 libro 社区共同发布 AWELNotebook 功能

libro：灵活定制、轻松集成的 Notebook 产品方案。

社区地址：https://github.com/difizen/libro

使用教程：

1.进入AWEL工作流，进入all_in_one_entranceworkflow

2.新建Notebook

3.编写awel算子并执行

import asyncio
from dbgpt.core.awel import DAG, MapOperator
with DAG("awel_hello_world") as dag:task = MapOperator(map_function=lambda x: print(f"Hello, {x}!"))
await task.call(call_data="world")

支持三元组图谱与文档结构图谱混合分析，通过并行知识抽取提升知识图谱图谱索引构建性能。

DB-GPT GraphRAG与微软GraphRAG在文档抽取token消耗，Global/Local检索性能的对比。

	DB-GPT	GraphRAG (Microsoft)
Doc Tokens	42631	42631
Triplets Graph	nodes: 666; edges: 1066	nodes: 644; edges: 1048
Doc Structure Graph	nodes: 123; edges: 1095	不支持
Prompt Tokens	361054	744990
Completion Tokens	41315	227230
Total Tokens	402369	972220
Global Search	10s	40s
Local Search	15s	15s

注意: 沙箱环境依赖 Lyric 的支持，

Lyric: A Rust-powered secure runtime for AI-Agent.

Lyric地址https://github.com/lyric-project/lyric

安装依赖：

pipinstall-e".[code]"

Lyric使用示例：

import asynciofrom lyric import DefaultLyricDriver
python_code = """def add(a, b):return a + bresult = add(1, 2)print(result)"""
js_code = """console.log('Hello from JavaScript!');"""
async def main():lcd = DefaultLyricDriver(host="localhost", log_level="ERROR")lcd.start()
# Load workers(default: Python, JavaScript)await lcd.lyric.load_default_workers()
# Execute Python codepy_res = await lcd.exec(python_code, "python")print(py_res)
# Execute JavaScript codejs_res = await lcd.exec(js_code, "javascript")print(js_res)
# Stop the driverlcd.stop()
asyncio.run(main())
