Hey @mateus-melo0217! 👋 I'm here to help you with any bugs, questions, or contributions you have regarding LangChain. I'm not a human, but I can still assist you while you wait for a human maintainer. Let's squash this bug together!

To successfully import LangChain packages on MacOS Sonoma 14.5, you need to ensure that all necessary packages are installed. Here are the steps:

1. Open your terminal.
2. Run the following commands to install the required packages:

pip install langchain
pip install langchain-community
pip install langchain-openai

After installing these packages, you should be able to import them in your Python script:

from langchain.chains import GraphCypherQAChain
from langchain_community.graphs import MemgraphGraph
from langchain_openai import ChatOpenAI

Make sure you have the correct versions of dependencies for langchain_community.graphs and langchain_openai:

For langchain_community.graphs:

• python = ">=3.8.1,<4.0"
• langchain-core = "^0.2.10"
• langchain = "^0.2.6"
• SQLAlchemy = ">=1.4,<3"
• requests = "^2"
• PyYAML = ">=5.3"
• aiohttp = "^3.8.3"
• tenacity = "^8.1.0,!=8.4.0"
• dataclasses-json = ">= 0.5.7, < 0.7"
• langsmith = "^0.1.0"
• numpy = [
  { version = "^1", python = "<3.12" },
  { version = "^1.26.0", python = ">=3.12" },
  ]

For langchain_openai:

• python = ">=3.8.1,<4.0"
• langchain-core = ">=0.2.2,<0.3"
• openai = "^1.32.0"
• tiktoken = ">=0.7,<1" ^[1][2].

This should resolve the import issues on MacOS Sonoma 14.5.
