Interestingly, this is still not working for me:

from griptape.drivers import OllamaPromptDriver
from griptape.structures import Agent
from griptape.tools import CalculatorTool

agent = Agent(
    stream=True,
    prompt_driver=OllamaPromptDriver(model="llama3.2"),
    tools=[CalculatorTool()],
)
agent.run("What is (192 + 12) ^ 4")
