🗺️ 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

Upcoming Features

• Dedicated Querying/Chat UI that interacts with the API
• Dockerfile for easier deployment
• Launch your own GraphRAG API server for use in external applications
• Experimental: Mixture of Agents for Indexing/Query of knowledge graph
• Support for more file formats (CSV, PDF, etc.)
• Web search/Scraping capabilities
• 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.

🚀 Getting Started with GraphRAG Local

GraphRAG is designed for flexibility, allowing you to quickly create and initialize your own indexing directory. Follow these steps to set up your environment:

1. Create the Indexing Directory

This repo comes with a pre-made Indexing folder but you may want to make your own, so here are the steps. First, create the required directory structure for your input data and indexing results:

mkdir -p ./indexing/input

This directory will store:

• Input .txt files for indexing
• Output results
• Prompts for Prompt Tuning

2. Add Sample Data (Optional)

If you want to start with sample data, copy it to your new input directory:

cp input/* ./indexing/input

You can also add your own .txt files to this directory for indexing.

3. Initialize the Indexing Folder

Run the following command to initialize the ./indexing folder with the required files:

python -m graphrag.index --init --root ./indexing

4. Configure Settings

Move the pre-configured settings.yaml file to your indexing directory:

mv settings.yaml ./indexing

This file contains the main configuration, pre-set for use with local models.

5. Customization

You can customize your setup by modifying the following environment variables:

• ROOT_DIR: Points to your main indexing directory
• INPUT_DIR: Specifies the location of your input files

🖥️ 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!
