tools를 langchain의 tools수 있다고 하셨는데, 자꾸 type 오류가 발생하는데요

코드는 다음과 같습니다.

from langchain.agents import Tool

from langchain_community.tools.tavily_search import TavilySearchResults

tavily = TavilySearchResults()

tavily = Tool(

    name="tavily search",

    func = tavily.invoke,

    description="Web search tool"

)

from crewai import Agent

asd = Agent(

    role='a',

    goal="a",

    backstory="a",

    tools=[tavily]

)

여기서,
