```
model = GenerativeModel("gemini-pro")
print(model.generate_content(

    tools=[weather_tool],
    tool_config=tool_config,
))
```
Use ToolConfig in chat:
```
model = GenerativeModel(
    "gemini-pro",

    tools=[weather_tool],
    tool_config=tool_config,
)
chat = model.start_chat()
print(chat.send_message("What is the weather like in Boston?"))
print(chat.send_message(
    Part.from_function_response(
        name="get_current_weather",
