1. Install either [email protected] or [email protected] on the operating system of your choice.
2. Set up a Python virtual environment and activate it:

   $ python3 -m venv venv
   $ source venv/bin/activate

3. You will be using the following packages to develop the demo described in this chapter:
   • pandas: Helps with data preprocessing and handling
   • numpy: Handles numerical data
   • openai: For the embedding model and invoking the LLM
   • pymongo: For the MongoDB Atlas vector store and full-text search
   • s3fs: Allows loading data directly from an S3 bucket
   • langchain_mongodb: Enables vector search in MongoDB Atlas using a LangChain wrapper
   • langchain: Used to build a RAG application
   • langchain-openai: Enables you to interact with OpenAI chat models
   • boto3: Enables you to interact with AWS...
