import asyncio
from agno.knowledge.knowledge import Knowledge
from agno.vectordb.pgvector import PgVector

knowledge = Knowledge(

# Add from local file to the knowledge base

        metadata={"user_tag": "Engineering Candidates"},
        skip_if_exists=True,  # True by default
    )

# Add from local file to the knowledge base, but don't skip if it already exists
asyncio.run(
    knowledge.add_content_async(
        name="CV",
        path="cookbook/knowledge/testing_resources/cv_1.pdf",
