Something about agent.python_executor and additional_authorized_imports

[baixianger]

I have a question about a code snippet from the smolagents web browser automation example:

from smolagents import CodeAgent
from smolagents.agents import ActionStep

# Create the agent
agent = CodeAgent(
    tools=[go_back, close_popups, search_item_ctrl_f],
    model=model,
    additional_authorized_imports=["helium"],
    step_callbacks=[save_screenshot],
    max_steps=20,
    verbosity_level=2,
)

# Import helium for the agent
agent.python_executor("from helium import *", agent.state)

In this code, there are two instances where the helium library is referenced:
1. The additional_authorized_imports=["helium"] parameter in the CodeAgent initialization.
2. The agent.python_executor("from helium import *", agent.state) command.

I understand that additional_authorized_imports is used to grant the agent permission to use specific packages in the code it generates. Does this mean that if a tool within the agent requires the helium library, it doesn’t need to be listed here, and this parameter is solely for imports in the agent’s own code?

Additionally, could someone clarify the purpose of the second reference, agent.python_executor("from helium import *", agent.state)? Is this command necessary to explicitly import the helium functions into the agent’s execution environment, allowing it to utilize them during its operations?

Thank you for your assistance in understanding these distinctions.
