Usage

1

Create a virtual environment

Open the Terminal and create a python virtual environment.

python3 -m venv .venv
source .venv/bin/activate
2

Set your API key

export IBM_WATSONX_API_KEY=xxx
export IBM_WATSONX_PROJECT_ID=xxx
3

Install libraries

pip install -U ibm-watsonx-ai sqlalchemy pgvector psycopg pypdf openai agno
4

Set up PostgreSQL with pgvector

You need a PostgreSQL database with the pgvector extension installed. Adjust the db_url in the code to match your database configuration.

5

Run Agent

python cookbook/models/ibm/watsonx/knowledge.py
6

For subsequent runs

After the first run, comment out the knowledge_base.load(recreate=True) line to avoid reloading the PDF.

This example shows how to integrate a knowledge base with IBM WatsonX. It loads a PDF from a URL, processes it into a vector database (PostgreSQL with pgvector in this case), and then creates an agent that can query this knowledge base.

Note: You need to install several packages (pgvector, pypdf, etc.) and have a PostgreSQL database with the pgvector extension available.
