#4226 PDF-to-ChromaDB with Tkinter GUI #4226 Provide a Python application to read a PDF and convert it to text, chunk and index the text chunks, and save it in a ChromaDB database Building a local RAG (Retrieval-Augmented Generation) pipeline is a great way to handle your documents. To get this running, we'll use LangChain for the orchestration, PyPDF for parsing, and ChromaDB as our vector warehouse. 🛠️ Prerequisites You'll need to install a few libraries. I recommend using a virtual environment: pip install langchain langchain-community langchain-chroma pypdf sentence-transformers 🐍 The Python Application This script handles the entire pipeline: loading the PDF, breaking it into manageable pieces, and storing it in a persistent database. import os from langchain_community.document_loaders import PyPDFLoader from langchain_text_splitters import RecursiveCharacterTextSplitter from langchain_community.embeddings import HuggingFaceEmbeddings from langchain_chroma i...
