Installation

To get started with this project, follow these steps:

1. Clone the repository:

   git clone https://github.com/dev-arctik/LangGraph_Learning.git
   cd LangGraph_Learning

2. Install Poetry (if not already installed):

   # On macOS and Linux
   curl -sSL https://install.python-poetry.org | python3 -
   
   # On Windows (PowerShell)
   (Invoke-WebRequest -Uri https://install.python-poetry.org -UseBasicParsing).Content | python -

3. Install dependencies using Poetry:

   poetry install

4. Activate the Poetry virtual environment:

   poetry shell

Setup

To run the code effectively, create a .env file in the root directory to store your API keys and configuration settings. This is necessary for using the various APIs involved in the project.

You can use the provided .env.example file as a template:

cp .env.example .env

Then edit the .env file with your actual API keys.

You will get the langsmith api (optional) on langsmith Website

The .env file should contain the following variables:

# OpenAI
OPENAI_API_KEY="your_openai_api_key_here"

# LangSmith
LANGCHAIN_TRACING_V2=true
LANGCHAIN_ENDPOINT="https://api.smith.langchain.com"
LANGCHAIN_API_KEY="your_langchain_api_key_here"
LANGCHAIN_PROJECT="your_project_name_here"

# Tavily
TAVILY_API_KEY="your_tavily_api_key_here"

Replace 'your_openai_api_key_here' with your actual OpenAI API key.

Note: If you choose to use a different LLM (Language Learning Model), refer to the LangChain documentation and adjust the code as needed.

Usage

You can run individual files with the following command:

poetry run python [file_name.py]

Alternatively, if you have activated the Poetry shell:

python [file_name.py]
