[Python] CREW AI tool not using ChatGroq

Here is my tools.py file

import os
from dotenv import load_dotenv
from langchain_groq import ChatGroq
from crewai_tools import PDFSearchTool, SerperDevTool

load_dotenv()

# Initialize the ChatGroq model
llm = ChatGroq(
model="llama-3.1-70b-versatile",
temperature=0.7,
groq_api_key=os.getenv('GROQ_API_KEY'),
verbose=True
)


os.environ['SERPER_API_KEY'] = os.getenv('SERPER_API_KEY')

# Initialize the tool allowing for any PDF content search if the path is provided during execution
pdf_tool = PDFSearchTool()

# Initialize the tool for internet searching capabilities
serper_tool = SerperDevTool()


also I have added

llm = ChatGroq(
model="llama-3.1-70b-versatile",
temperature=0.7,
groq_api_key=os.getenv('GROQ_API_KEY'),
verbose=True
)


in my agents.py also and mentioned in every Agent.

But when I run

python crew.py


the error comes:

UserWarning: Valid config keys have changed in V2:

Please help me

I know about the document from crewai that I should try this way

tool = PDFSearchTool(
config=dict(
llm=dict(
provider="ollama", # or google, openai, anthropic, llama2, ...
config=dict(
model="llama2",
# temperature=0.5,
# top_p=1,
# stream=true,
),
),
embedder=dict(
provider="google", # or openai, ollama, ...
config=dict(
model="models/embedding-001",
task_type="retrieval_document",
# title="Embeddings",
),
),
)
)


But how to use ChatGroq with it.
