Gemini 2.0 with GoogleSearch and CodeExecution

[markusvonstaden]

Hi there,

In the past I have used the OpenAI Assistants API, but I want to give Gemini a try.
So I tried this basic code:

from google import genai
from google.genai.types import GenerateContentConfig, Tool, GoogleSearch, ToolCodeExecution

client = genai.Client(vertexai=True, project=MY-PROJECT-ID, location="us-central1")

search_tool = Tool(google_search=GoogleSearch())
code_execution_tool = Tool(code_execution=ToolCodeExecution())

config = GenerateContentConfig(
tools=[search_tool, code_execution_tool],
)

chat_session = client.chats.create(model="gemini-2.0-flash-001", config=config)

while True:
    user_input = input("User: ")
    if user_input == "exit":
    break
    response = chat_session.send_message(user_input)
    print("Model:", response.text)

 But this does not work, I get the Error

{'error': {'code': 400, 'message': 'At most one tool is supported.', 'status': 'INVALID_ARGUMENT'}}

 Instead creating one tool with both enabled results in

tool = Tool(google_search=GoogleSearch(), code_execution=ToolCodeExecution())

{'error': {'code': 400, 'message': 'Request contains an invalid argument.', 'status': 'INVALID_ARGUMENT'}}

Is there any way to enable both? I did not find anything in the documentation or GitHub Repo.

Any help would be appreciated
