Why the same python tools run many times?

[KevinZhang19870314]

I am using Assistant with python tools, sometimes it will run many times for the same tools (see below log for tools start_time and end_time), and it also cause the tokens usage increase to double or more. So what is the reason? How can I fix it?

Here is the code and log:

--- code

import os
import pathlib

from phi.assistant import Assistant
from phi.llm.openai import OpenAIChat
from phi.tools.python import PythonTools
from pydantic import BaseModel, Field
from dotenv import load_dotenv

load_dotenv()

STORAGE_ROOT = os.getenv('STORAGE_ROOT')
PYTHON_TOOLS_STORAGE = os.getenv('PYTHON_TOOLS')
PYTHON_TOOLS_STORAGE_FOLDER_PATH = os.path.join(STORAGE_ROOT, PYTHON_TOOLS_STORAGE)


class TradesAPIParameter(BaseModel):
	startTime: str = Field(None, description="Start time for transaction creation. Use the python_tools tool to generate the code and get the value, in the format '2024-07-26T00:00:00+08:00'.")
	endTime: str = Field(None, description="End time for transaction creation. Use the python_tools tool to generate the code and get the value, in the format '2024-07-26T23:59:59+08:00'.")
	page: int = Field(1, description="Current page number for pagination.")
	size: int = Field(10, description="Number of records per page for pagination.")


movie_assistant = Assistant(
	# llm=OpenAIChat(model="gpt-3.5-turbo"),
	# llm=OpenAIChat(model="gpt-4o"),
	llm=OpenAIChat(model="gpt-4o-mini"),
	description="You are a parameter parser for the transaction record query API, responsible for parsing the natural language input by the user into the parameter fields required by this API.",
	output_model=TradesAPIParameter,
	tools=[PythonTools(base_dir=pathlib.Path(PYTHON_TOOLS_STORAGE_FOLDER_PATH))],
	show_tool_calls=False,
	debug_mode=False,
)

params = movie_assistant.run("Query the records of the last seven days, and 14 records are displayed per page.")
print("=========================")
print(params)
print(movie_assistant.llm.metrics)
print("=========================")

And by the way, is my prompt not worked?

@KevinZhang19870314 , this appears to be a model limitation. Can you please share the output while using GPT 4o as the model?

Thanks, GPT 4o works as normal, no python tools will be called more times.

So, I want to know the logic for different model while call the python tools. Can we control this logic, or what happened when call python tools many times?
