Information Retrieval from Multiple PDF 💁💬 with PaLM2

Overview

The Information Retrieval from Multiple PDF app is a Streamlit-based application that allows users to upload and interact with multiple PDF files. Using PaLM2, LangChain, and FAISS, the app enables users to ask questions about the content of the PDFs and receive accurate, contextually relevant responses.

How to Run?

STEPS:

1. Clone the Repository

   Project repo: https://github.com/Amartya-007/PDF-Reader-App

   git clone https://github.com/Amartya-007/PDF-Reader-App.git
   cd PDF-Reader-App

2. Create a Conda Environment

   After opening the repository, create and activate a Conda environment:

   conda create -n llmapp python=3.8 -y
   conda activate llmapp

3. Install the Requirements

   Install the necessary Python packages:

   pip install -r requirements.txt

4. Set Up Environment Variables

   Create a .env file in the root directory and add your Google API key. You can generate an API key by following the instructions at Google PaLM API Setup:

   GOOGLE_API_KEY= "xxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

5. Run the App

   Finally, run the Streamlit application:

   streamlit run app.py

6. Open the App

   Open your web browser and navigate to:

   http://localhost:8501

Usage

1. Upload PDF Files

   • Use the sidebar to upload one or more PDF files.
   • Click the "Submit" button to process the files.

2. Ask Questions

   • Once the PDFs are processed, enter your question in the text input box.
   • The app will provide answers based on the content of the uploaded PDFs.

3. View Chat History

   • The chat history displays the questions you’ve asked and the app’s responses, simulating a conversation interface.
