CSV URL Knowledge Base

The CSVUrlKnowledgeBase reads CSVs from urls, converts them into vector embeddings and loads them to a vector database.

​Usage

We are using a local PgVector database for this example. Make sure it’s running

knowledge_base.py

from bitca.knowledge.pdf import PDFUrlKnowledgeBase
from bitca.vectordb.pgvector import PgVector

knowledge_base = CSVUrlKnowledgeBase(
    urls=["csv_url"],
    # Table name: ai.csv_documents
    vector_db=PgVector(
        table_name="csv_documents",
        db_url="postgresql+psycopg://ai:ai@localhost:5532/ai",
    ),
)

Then use the knowledge_base with an Agent:

agent.py

from bitca.agent import Agent
from knowledge_base import knowledge_base

agent = Agent(
    knowledge=knowledge_base,
    search_knowledge=True,
)
agent.knowledge.load(recreate=False)

agent.print_response("Ask me about something from the knowledge base")
