This recipe shows how to use personalized memories and summaries in an agent.
Steps:
1. Run: `./cookbook/scripts/run_pgvector.sh` to start a postgres container with pgvector
2. Run: `uv pip install ollama sqlalchemy 'psycopg[binary]' pgvector` to install the dependencies
3. Run: `python cookbook/92_models/ollama/memory.py` to run the agent
