PPTX Reader

The PPTX Reader allows you to read and extract text content from PowerPoint (.pptx) files, converting them into vector embeddings for your knowledge base.

Code

pptx_reader.py

from agno.agent import Agent
from agno.knowledge.knowledge import Knowledge
from agno.knowledge.reader.pptx_reader import PPTXReader
from agno.vectordb.pgvector import PgVector

db_url = "postgresql+psycopg://ai:ai@localhost:5532/ai"

# Create a knowledge base with the PPTX documents
knowledge = Knowledge(
    # Table name: ai.pptx_documents
    vector_db=PgVector(
        table_name="pptx_documents",
        db_url=db_url,
    ),
)
# Load the knowledge
knowledge.add_content(
    path="data/pptx_files",
    reader=PPTXReader(),
)

# Create an agent with the knowledge
agent = Agent(
    knowledge=knowledge,
    search_knowledge=True,
)

# Ask the agent about the knowledge
agent.print_response("What can you tell me about the content in these PowerPoint presentations?", markdown=True)

Usage

1. Create a virtual environment

   Open the Terminal and create a python virtual environment.

2. Install libraries

   pip install -U python-pptx sqlalchemy psycopg pgvector agno
   
3. Run PgVector

   docker run -d \
     -e POSTGRES_DB=ai \
     -e POSTGRES_USER=ai \
     -e POSTGRES_PASSWORD=ai \
     -e PGDATA=/var/lib/postgresql/data/pgdata \
     -v pgvolume:/var/lib/postgresql/data \
     -p 5532:5432 \
     --name pgvector \
     agno/pgvector:16
   
4. Run Agent
