How to build a Streamlit UI for Local PDF RAG [Ollama models]

In this tutorial, we'll take our local Ollama PDF RAG (Retrieval Augmented Generation) pipeline to the next level by adding a sleek Streamlit UI! 🚀

We'll build on our previous PDF RAG project and create an interactive web application that allows users to upload a PDF, ask questions, and get accurate, context-aware answers. Here's what we'll cover:

✅ Quick recap of our previous RAG pipeline using Ollama and LangChain
✅ Implementing PDF upload functionality with visual feedback
✅ Creating an interactive Q&A interface with real-time responses
✅ Displaying PDF content alongside the Q&A interface
✅ Polishing the UI with error handling and user-friendly features

By the end of this tutorial, you'll have a user-friendly PDF Q&A application that combines the strength of RAG with the interactivity of Streamlit! 🎈

Nice video! Could you please let me know which python version you use in your code mentioned in your video?

It's giving me the below error on running the streamlit app:

ConnectError: [WinError 10061] No connection could be made because the target machine actively refused it

Please look into it

Awesome. i have one question here, how to handle pdf file content like two columns in same page?

[dhatric]

Every time I close, I have to upload the pdf again and it creates chunks and embeddings from scratch even if it is the same pdf.
And it always says no question in the prompt. But generated queries is working.I am using Llama3

[UrveshkumarKoshti]

Did you create the Python Virtual enviornment to create and run this code?

[michelecarbonella]

How many documents is it possible upload if I change this argument accept_multiple_files=False to True?

[bhagavanprasad]

I am getting error saying "Question: (None specified"

Based on the provided context, I will answer the question.
Question: (None specified)
Since there is no specific question, I will assume that the goal is to summarize Bhagavan Prasad's work experience and skills.

Am I doing any mistake?
