To resolve the Pydantic deprecation issue when running Langflow version 1.0.15 on macOS Sonoma Version 14.6.1 with Python 3.12, you can filter out the deprecation warnings by adding the following line to your code:

import warnings
from pydantic import PydanticDeprecatedSince20

warnings.filterwarnings("ignore", category=PydanticDeprecatedSince20)

This line is already present in the provided main.py file of Langflow:

# Ignore Pydantic deprecation warnings from Langchain
warnings.filterwarnings("ignore", category=PydanticDeprecatedSince20)

Ensure that this line is executed before any Pydantic-related code runs. This will suppress the deprecation warnings and allow your application to run without displaying these warnings [1][2].

Additionally, Langflow's pyproject.toml specifies the compatible Python versions and dependencies. According to the pyproject.toml file, Langflow supports Python versions >=3.10,<3.12 and uses Pydantic version ^2.5.0. Since you are using Python 3.12, you might encounter compatibility issues. Downgrading your Python version to a supported version (e.g., Python 3.11) could help resolve these issues [3].

same problem in my MacBook (macOS sonoma 14.6.1 + Python 3.12.5 + langflow 1.0.15 or 1.0.14) but it worked on another MacBook (macOS sonoma 14.6 + Python 3.12.5 + langflow 1.0.14)

Hi @bruno-growthsales and @yorkew-east8 ,

I'm trying to reproduce the issue on my machine by installing Langflow 1.0.5 in a virtual environment, but it seems to be working fine for me.

Regarding the Pydantic warnings, these are just deprecation warnings about features that will be removed in the future and shouldn't affect the execution of the flows.

Therefore, I believe the issue might be related to something else. Could you provide more details or share a flow where you're experiencing this problem?

hi, @italojohnny, you can see the installation and execution in this video in less than 5 min.

hi, @bruno-growthsales , Despite the slowness, which is extremely annoying, there are no errors shown in your video, so I can't deduce the problem... Would you mind running the same test using the command: langflow run --log-level debug?

Hello @italojohnny, here is the problem following the same process as in the video.

@italojohnny I update to 1.0.16 and retried today, problem still exist: building never end. ( macOS 14.6.1(M2) + Python 3.12.5 + LangFlow 1.0.16 )

btw, I fixed 2 problems to get there:

  1. pip access timeout ./venv/lib/python3.12/site-packages/langflow/main.py Ln321 I add a timeout to reduce errors when get file from pip
  2. an ValueError: invalid literal for int() with base 10: '' in "/custom_component/update" ./venv/lib/python3.12/site-packages/langflow/api/v1/endpoints.py Ln597

here is final logs: 

$ langflow run --log-level=debug

Hello @bruno-growthsales and @yorkew-east8 . I deeply regret not being able to resolve your issue so far... This issue has lost cohesion. It started with problems related to Pydantic messages and has now diverged into different paths for each of you.

@bruno-growthsales , the last log you showed points to the following error: UnicodeEncodeError: 'ascii' codec can't encode characters in position 1013-1081.

@yorkew-east8 , the last log you showed points to the following warnning: RuntimeWarning: Enable tracemalloc to get the object allocation traceback.

I suspect that you may be dealing with some difficult-to-reproduce performance bugs, which we are very interested in discovering and resolving to improve the reliability of our code. Therefore...

To maintain my sanity and keep things a bit more organized for future reference, would you mind if I close this current issue and you both open new individual issues with as much evidence as you can provide? Preferably using version 1.0.16 (if you do not intend to use Postgres).

@yorkew-east8 I solve the issue, using mini conda and Chrome browser on my Mac OS M1. Follow this steps of install https://conda.io/projects/conda/en/latest/user-guide/install/macos.html I hope it helps you!
