Building a Chat GPT with Racks

Welcome to this video where we will explore how to build a Chat GPT using Racks from the Lama index. If You're new here, this is the third video in a series on creating GPTS. In the first video, we covered how to Create GPTs from OpenAI, and in the Second video, we explored Open GPTs from Langan.

In this video, we will dive into Racks, a powerful tool inspired by the OpenAI GPTs, and learn how to create a chatbot using natural language. We will walk you through the step-by-step process of cloning the repository, dealing with any issues you may encounter, and building the chatbot using the RAG pipeline.

Let's get started!

Introduction

In this video, we will explore how to build a Chat GPT using Racks from the Lama index. Racks is an excellent tool that allows you to create a chatbot using natural language and your own data. Through the use of the Builder agent, you can automate the heavy lifting required to develop your chatbot. The resulting RAG (Retrieval-Augmented Generation) pipeline enables you to create a powerful chatbot using information provided in natural language.

Cloning the Repository

The first step to getting started with Racks is to clone the GitHub repository into your own account. By forking the repository, you can make changes and contribute to the project if you wish. Once you have completed this step, you can open the repository in GitHub Cod Space or clone it locally to your machine.

Understanding the GitHub Repository

Before diving into the project, it's helpful to have a high-level understanding of the GitHub repository. Take a moment to Read the Readme file to familiarize yourself with the project's purpose and functionality. The Readme provides an overview of Racks and demonstrates a small demo of its capabilities. It explains that Racks is an exemplar app that creates a RAG pipeline using natural language. The Builder agent handles the heavy lifting required to generate the pipeline, allowing you to provide information using natural language.

Installation and Setup

To set up Racks, you will need to create a virtual environment and install the necessary dependencies using Poetry. Poetry is a Python dependency management tool that simplifies the installation process. By following the installation and setup instructions provided in the repository's Readme file, you can ensure that you have the correct environment and dependencies in place for running Racks.

Creating the Virtual Environment

In order to isolate the dependencies for Racks, it is recommended to create a virtual environment. By following the instructions in the repository's Readme file, you can create and activate the virtual environment using a Python version of 3.8 or higher. This ensures that Racks and its dependencies are installed within the virtual environment and do not interfere with your system's other Python configurations.

Installing Poetry

Next, you will need to install Poetry, a dependency management tool, within your virtual environment. By running the provided command, you can install Poetry and ensure that it is successfully installed by running the version command. Poetry will allow you to manage your project's dependencies and ensure a smooth installation process.

Creating the Streamlit App

Once you have set up your virtual environment and installed Poetry, you can proceed to create the Streamlit app. Streamlit is the framework used to provide the user interface for interacting with the chatbot. By launching the Streamlit app, you can begin the process of building your chatbot using Racks.

Configuring the RAG Pipeline Parameters

To configure the RAG pipeline parameters, you can refer to the Streamlit app's homepage. Here, you will find options to customize the chatbot's behavior, such as the top-k value, chunk size, and the selected language model. You can experiment with different settings to achieve the desired result. Additionally, there is an "Update Agent" button that allows you to update the agent's configuration if necessary.

Updating the Agent

Once you have configured the RAG pipeline parameters, you can update the agent to Apply the changes. By clicking the "Update Agent" button, you ensure that the agent's settings Align with your specified configuration. This step is crucial for the agent to generate accurate responses Based on the provided information.

Interacting with the Chatbot

After configuring the RAG pipeline and updating the agent, you can begin interacting with your chatbot. The Streamlit app provides a user-friendly interface where you can ask questions and receive responses from the chatbot. Experiment with different queries to test your chatbot's capabilities and evaluate its performance.

Including Summarization and Web Search

To enhance the functionality of your chatbot, you can include summarization and web search capabilities. By enabling summarization, the chatbot can provide condensed summaries of documents or Texts. Additionally, web search enables the chatbot to retrieve information from the internet, expanding its knowledge beyond the provided data. Configuring these features allows your chatbot to deliver more comprehensive and informative responses.

Troubleshooting and Limitations

While using Racks, you might encounter certain limitations or face issues. It is important to troubleshoot any problems that arise. Refer to the documentation and explore the open-source community for potential solutions. Keep in mind that Racks is an evolving project, so improvements and updates may be released to address known limitations and enhance its capabilities.

Conclusion

Racks from the Lama index offers a powerful framework for building chat GPTs using natural language. By following the steps outlined in this video, you can successfully set up Racks, create a chatbot, and Interact with it through the Streamlit app. Experiment with different parameters, customize the RAG pipeline, and explore the possibilities of the chatbot's capabilities. Have fun and enjoy building your Own Chat GPT with Racks!
