Project description
MAP2GPT
description
This project is a versatile and powerful search tool that leverages state-of-the-art natural language processing models to provide relevant and contextually rich results. The primary goal of this project is to build a semantic search engine for textual content from various sources such as PDF files and Wikipedia pages.
The project utilizes the GPT-3.5-turbo model for generating responses and French Semantic model to create embeddings of textual data. Users can build an index of embeddings from a PDF file or a Wikipedia page, explore the index interactively, and deploy the search functionality on Telegram. The search results are presented as the top k relevant chunks of information, which are then used as context to generate an informative response from the GPT-3.5-turbo model.
The project is implemented in Python, and it employs several open-source libraries such as Click, OpenAI, Wikipedia, PyTorch, Tiktoken, and Rich. The code is organized into modular functions and classes, making it easy to understand, maintain, and extend. The main script provides a command-line interface for users to interact with the project's functionalities.

Installation
To install the necessary dependencies, run the following command:
python -m venv env
source env/bin/activate
pip install --upgrade pip
pip install map2gpt
Supported Transformer Models
This project supports a variety of transformer models, including models from the Hugging Face Model Hub and sentence-transformers. Below are some examples: - Hugging Face Model: 'Sahajtomar/french_semantic' - Sentence-Transformers Model: 'paraphrase-MiniLM-L6-v2', 'all-mpnet-base-v2', etc...
Please ensure that the model you choose is compatible with the project requirements and adjust the --transformer_model_name
option accordingly.

Module usage
# build index from wikipedia page url
from map2gpt import GPTRunner
runner = GPTRunner(
device='cpu',
