Tutorial Overview

This tutorial guides you through the process of building a powerful and interactive Streamlit application that integrates LangChain and the Google Gemini API. The application functions as a smart AI assistant capable of real-time interactions, including:

  • Web searching
  • Wikipedia content retrieval
  • Mathematical calculations
  • Memory storage for key details
  • Conversation history management

This setup allows developers, researchers, and AI enthusiasts to create a multi-agent system directly from their browsers with minimal code and maximum flexibility.

Installation and Setup

To get started, install the necessary Python and Node.js packages:

!pip install -q streamlit langchain langchain-google-genai langchain-community
!pip install -q pyngrok python-dotenv wikipedia duckduckgo-search
!npm install -g localtunnel

Environment Configuration

Set up your environment by configuring the Google Gemini API key and ngrok authentication token:

GOOGLE_API_KEY = "Use Your API Key Here" 
NGROK_AUTH_TOKEN = "Use Your Auth Token Here" 
os.environ["GOOGLE_API_KEY"] = GOOGLE_API_KEY

Creating Tools for the AI Agent

Define a class to equip the AI agent with specialized capabilities, including:

  • A calculator for safe mathematical expression evaluation.
  • Memory tools to save and recall information across interactions.
  • A date and time tool to fetch the current date and time.

These tools enable the Streamlit AI agent to respond contextually and intelligently.

Building the Multi-Agent System

The core of the application is the MultiAgentSystem class, which integrates the Gemini Pro model using LangChain and initializes essential tools. It includes:

  • Web searching capabilities via DuckDuckGo and Wikipedia.
  • Memory management for user preferences and context.
  • A chat method for processing user input and generating intelligent responses.

Creating the Streamlit Application

The application features an interactive web interface, allowing users to:

  • Input API keys and configure agent capabilities.
  • Engage in real-time chat with the AI assistant.
  • Access a memory store for previously saved information.

Example queries help users understand the capabilities of the AI assistant.

Ngrok Setup for Public Access

To expose the Streamlit app to the internet, set up ngrok authentication and provide instructions for obtaining an ngrok token:

def setup_ngrok_auth(auth_token):
   """Setup ngrok authentication"""
   try:
       from pyngrok import ngrok, conf
       conf.get_default().auth_token = auth_token
       return True
   except ImportError:
       return False

Deployment

The application can be deployed in a local environment or Google Colab, allowing for easy access and sharing. The deployment process includes:

  • Starting the Streamlit server in the background.
  • Creating a public URL with ngrok for external access.
  • Providing alternative tunneling options if ngrok fails.

Conclusion

By following this tutorial, you will have a fully functional AI agent running within a Streamlit interface, capable of responding to queries, remembering user inputs, and sharing its services publicly. This setup serves as a foundation for developing advanced AI applications tailored to various business needs.
