🕸️ GraphRAG Local

Welcome to GraphRAG Local with Index/Prompt-Tuning and Querying/Chat UIs! This project is an adaptation of Microsoft's GraphRAG, tailored to support local models and featuring a comprehensive interactive user interface ecosystem.

📄 Research Paper

For more details on the original GraphRAG implementation, please refer to the GraphRAG paper.

🌟 Features

• API-Centric Architecture: A robust FastAPI-based server (api.py) serving as the core of the GraphRAG operations.
• Dedicated Indexing and Prompt Tuning UI: A separate Gradio-based interface (index_app.py) for managing indexing and prompt tuning processes.
• Local Model Support: Leverage local models for LLM and embeddings, including compatibility with Ollama and OpenAI-compatible APIs.
• Cost-Effective: Eliminate dependency on costly cloud-based models by using your own local models.
• Interactive UI: User-friendly interface for managing data, running queries, and visualizing results (main app).
• Real-time Graph Visualization: Visualize your knowledge graph in 2D or 3D using Plotly (main app).
• File Management: Upload, view, edit, and delete input files directly from the UI.
• Settings Management: Easily update and manage your GraphRAG settings through the UI.
• Output Exploration: Browse and view indexing outputs and artifacts.
• Logging: Real-time logging for better debugging and monitoring.
• Flexible Querying: Support for global, local, and direct chat queries with customizable parameters (main app).
• Customizable Visualization: Adjust graph layout, node sizes, colors, and more to suit your preferences (main app).

🗺️ Roadmap

Important Note: The GraphRAG Local UI ecosystem is currently undergoing a major transition. While the main app remains functional, I am actively developing separate applications for Indexing/Prompt Tuning and Querying/Chat, all built around a robust central API. Users should expect some changes and potential instability during this transition period.

While it is currently functional, it has only been primarily tested on a Mac Studio M2.

My vision for the GraphRAG Local UI ecosystem is to become the ultimate set of tools for working with GraphRAG and local LLMs, incorporating as many cool features and knowledge graph tools as possible. I am continuously working on improvements and new features.

Recent Updates

• New API-centric architecture (api.py)
• Dedicated Indexing and Prompt Tuning UI (index_app.py)
• Improved file management and output exploration
• Background task handling for long-running operations
• Enhanced configuration options through environment variables and YAML files
• Web search capabilities

Upcoming Features

• Dedicated Querying/Chat UI that interacts with the API
• Dockerfile for easier deployment
• Experimental: Mixture of Agents for Indexing/Query of knowledge graph
• Support for more file formats (CSV, PDF, etc.)
• Advanced graph analysis tools
• Integration with popular knowledge management tools
• Collaborative features for team-based knowledge graph building

I am committed to making the GraphRAG Local UI ecosystem the most comprehensive and user-friendly toolset for working with knowledge graphs and LLMs. Your feedback and suggestions are much needed in shaping the future of this project.

Feel free to open an Issue if you run into an error, and I will try to address it as soon as possible to minimize any downtime you might experience.

📦 Installation and Setup

Follow these steps to set up and run the GraphRAG Local UI ecosystem:

1. Create and activate a new conda environment:

   conda create -n graphrag-local -y
   conda activate graphrag-local

2. Install the required packages:

   First install the GraphRAG dir from this repo (has changes not present in the Microsoft repo):

   pip install -e ./graphrag

   Then install the rest of the dependencies:

   pip install -r requirements.txt
   

3. Launch the API server:

   python api.py --host 0.0.0.0 --port 8012 --reload

4. If using Ollama for embeddings, launch the embedding proxy:

   python embedding_proxy.py --port 11435 --host http://localhost:11434

   Note: For detailed instructions on using Ollama embeddings with GraphRAG, refer to the EMBEDDING_PROXY_README.md file.

5. Launch the Indexing and Prompt Tuning UI (Uses the API):

   gradio index_app.py

OR

6. Launch the main interactive UI (Legacy app that does not use the API):

   gradio app.py

   or

   python app.py

7. Access the UIs:

   • Indexing and Prompt Tuning UI: Open your web browser and navigate to http://localhost:7861
   • Main UI (legacy): Open your web browser and navigate to http://localhost:7860

🖥️ GraphRAG Application Ecosystem

The GraphRAG Local UI ecosystem consists of three main components, each serving a specific purpose in the knowledge graph creation and querying process:

1. Core API (api.py)

The api.py file serves as the backbone of the GraphRAG system, providing a robust FastAPI-based server that handles all core operations.

Key features:

• Manages indexing and prompt tuning processes
• Handles various query types (local, global, and direct chat)
• Integrates with local LLM and embedding models
• Provides endpoints for file management and system configuration

Usage:

python api.py --host 0.0.0.0 --port 8012 --reload

Note: If using Ollama for embeddings, make sure to run the embedding proxy (embedding_proxy.py) alongside api.py. Refer to the EMBEDDING_PROXY_README.md for detailed instructions.

2. Indexing and Prompt Tuning UI (index_app.py)

Workflow Integration

1. Start the Core API (api.py) to enable backend functionality.
2. If using Ollama for embeddings, start the embedding proxy (embedding_proxy.py).
3. Use the Indexing and Prompt Tuning UI (index_app.py) to prepare your data and fine-tune the system.
4. (Optional) Use the Main Interactive UI (app.py) for visualization and legacy features.

This modular approach allows for greater flexibility and easier maintenance of the GraphRAG system. As development continues, the functionality of app.py will be gradually integrated into new, specialized interfaces that interact with the core API.

2. Indexing and Prompt Tuning UI (index_app.py)

The index_app.py file provides a user-friendly Gradio interface for managing the indexing and prompt tuning processes.

Key features:

• Configure and run indexing tasks
• Set up and execute prompt tuning
• Manage input files and explore output data
• Adjust LLM and embedding settings

Usage:

python index_app.py

Access the UI at http://localhost:7861

3. Main Interactive UI (Legacy App) (app.py)

The app.py file is the pre-existing main application, which is being phased out but still provides useful functionality.

Key features:

• Visualize knowledge graphs in 2D or 3D
• Run queries and view results
• Manage GraphRAG settings
• Explore indexed data

Usage:

python app.py

or

gradio app.py

Access the UI at http://localhost:7860

Workflow Integration

1. Start the Core API (api.py) to enable backend functionality.
2. Use the Indexing and Prompt Tuning UI (index_app.py) to prepare your data and fine-tune the system.
3. (Optional) Use the Main Interactive UI (app.py) for visualization and legacy features.

This modular approach allows for greater flexibility and easier maintenance of the GraphRAG system. As development continues, the functionality of app.py will be gradually integrated into new, specialized interfaces that interact with the core API.

Troubleshooting

• If you encounter any issues with the new API or Indexing UI, please check the console logs for detailed error messages.
• For the main app, if you can't run gradio app.py, try running pip install --upgrade gradio and then exit out and start a new terminal. It should then load and launch properly as a Gradio app.
• On Windows, if you run into an encoding/UTF error, you can change it to the correct format in the YAML Settings menu.

For any issues or feature requests, please open an issue on the GitHub repository. Happy knowledge graphing!
