[开发中]支持调用LangChain Community 中的Tool实现

[MrChengmo]

用户示例代码

import appbuilder
from appbuilder import LangChainToolWrapper
from langchain_community.tools import ShellTool


# 使用LangChain的ShellTool插件
component = LangChainToolWrapper(langchain_tool = ShellTool())
query = appbuilder.Message("echo 'hello world' && time")

answer = component.run(query)
print(answer.content)

结果输出

➜  appbuilder python3 -u langchain_wrapper.py
