Description:
Hello, I encountered an error while using the langgraph-codeact library related to weak references in the Command class. The error occurs during the execution and seems to be linked to how the Command object is handled. Below are the details:

Steps to Reproduce:

  1. Set up the environment with the langgraph-codeact library.
  2. Run a typical process involving the Command objects.
  3. Run using stream and put stream_mode to messages (run: examples/math_example.py)

Expected Behavior:
The process should execute without errors and handle the Command objects correctly.

Observed Behavior:
The execution get the following error, but dont fails or stop the workflow:

Error in StreamMessagesHandler.on_chain_end callback: TypeError("descriptor '__weakref__' for 'Command' objects doesn't apply to a 'Command' object")

Investigation and Cause:
I believe the issue is caused by the Command class not supporting weak references, or something like that.

Environment Details:

  • Python Version: 3.10.12
  • langgraph-codeact Version: 0.1.0
  • Operating System: wsl Ubuntu 22.04.5 LTS
  • Langchain-ollama.
  • Model: "qwen2.5:3b" localy.

The stacktrace:

First, thank you for answering me; it is very important to me.

The code

It is basically the example: Exemple

I just changed the input prompt to: 'calc the area and perimeter of circle with x cm of diameter, where x: 10x+26x=72'

import builtins
import contextlib
import io
import math
from typing import Any


from langgraph.checkpoint.memory import MemorySaver
from llm.llm import LLM_manager
from langgraph_codeact import create_codeact


def eval(code: str, _locals: dict[str, Any]) -> tuple[str, dict[str, Any]]:
    # Store original keys before execution
    original_keys = set(_locals.keys())

    try:
        with contextlib.redirect_stdout(io.StringIO()) as f:
            exec(code, {**builtins.__dict__, **math.__dict__}, _locals)
        result = f.getvalue()
        if not result:
            result = "<code ran, no output printed to stdout>"
    except Exception as e:
        result = f"Error during execution: {repr(e)}"

    # Determine new variables created during execution
    new_keys = set(_locals.keys()) - original_keys
    new_vars = {key: _locals[key] for key in new_keys}
    return result, new_vars

tools = [
    add,
    multiply,
    divide,
    subtract,
    exponentiation,
    sin,
    cos,
    radians,
    sqrt,
    ceil,
]

# get model
model = LLM_manager().set_ollama_model("qwen2.5:3b").model

code_act = create_codeact(model, tools, eval)
agent = code_act.compile()

if __name__ == "__main__":
    messages = [
        {
            "role": "user",
            "content": "calc the area and perimeter of circle with x cm of diameter, where x: 10x+26x=72",
        }
    ]
    all = None
    for typ, chunk in agent.stream(
        {"messages": messages},
        stream_mode=["values", "messages"],
        config={"configurable": {"thread_id": 1}},
    ):
        if typ == "messages":
            print(chunk[0].content, end="")
        elif typ == "values":
            print("\n\n---answer---\n\n", chunk)
            all = chunk

This is the output:

As I mentioned, it does not interrupt the process. It is simply thrown this error message, and my curiosity brought me here.

---answer---

{'messages': [HumanMessage(content='calc the area and perimeter of circle with x cm of diameter, where x: 10x+26x=72', additional_kwargs={}, response_metadata={}, id='196c2478-150f-4cd6-b357-0ec2413aca7a')]}
To solve this problem, we need to first find the value of (x) from the equation (10x + 26x = 72). After finding (x), which represents the diameter of the circle, we can calculate both the area and perimeter (circumference) of the circle.

Let's start by solving for (x).

  • The given equation is (10x + 26x = 72).
  • Combine like terms: (36x = 72).
  • Solve for (x): (x = \frac{72}{36}).

Once we have the value of (x), which is the diameter, we can calculate the radius ((r)) as half of the diameter. Then use these values to find both the area and perimeter (circumference) of the circle.

Let's perform these calculations.

  • Radius (r = \frac{x}{2}).
  • Area (A = \pi r^2).
  • Perimeter/Circumference (P = 2\pi r).

Now, let's write the Python code to compute these values.

from math import pi

# Solve for x from the equation 10x + 26x = 72
x = 72 / 36

# Calculate radius and area/circumference of circle with diameter x
radius = x / 2
area = pi * radius**2
perimeter = 2 * pi * radius

(x, radius, area, perimeter)

from math import pi

Solve for x from the equation 10x + 26x = 72

x = 72 / 36

Calculate radius and area/circumference of circle with diameter x

radius = x / 2
area = pi * radius**2
perimeter = 2 * pi * radius

(x, radius, area, perimeter)

We have determined that (x = 2). Now we can calculate the area and circumference of a circle with a diameter of (2) cm.

Given:

  • Diameter ((d)) = (2) cm.
  • Radius ((r)) = (\frac{d}{2} = \frac{2}{2} = 1) cm.

Using these values, we can calculate the area and circumference:

  • Area ((A)) of a circle is given by (A = \pi r^2).
  • Circumference ((P)) of a circle is given by (P = 2\pi r).

Let's compute these.

# Given values
diameter = x  # Diameter in cm, calculated as 2

# Radius calculation from diameter
radius = diameter / 2

# Calculate area and circumference using the radius
area = pi * radius**2
perimeter = 2 * pi * radius

(radius, area, perimeter)

Given values

diameter = x # Diameter in cm, calculated as 2

Radius calculation from diameter

radius = diameter / 2

Calculate area and circumference using the radius

area = pi * radius**2
perimeter = 2 * pi * radius

(radius, area, perimeter)

The calculations for a circle with a diameter of (2) cm yield:

  • Radius ((r)) = (1) cm.
  • Area ((A)) = (\pi \times 1^2 = \pi) square centimeters.
  • Circumference ((P)) = (2\pi \times 1 = 2\pi) centimeters.

So, the area of the circle is (\pi) square centimeters and the circumference is (2\pi) centimeters.
