llama-index packs panel_chatbot integration

🦙 Panel ChatBot Pack

Build a chatbot to talk to your Github repository.

Powered by LlamaIndex, OpenAI ChatGPT and HoloViz Panel.

💁‍♀️ Explanation

This template

• Downloads and indexes a Github repository using the llama_index GithubRepositoryReader. The default repository is holoviz/panel.
• Creates a VectorStoreIndex powered chat engine that will retrieve context from that data to respond to each user query.
• Creates a Panel ChatInterface UI that will stream each answer from the chat engine.

🖥️ CLI Usage

You can download llamapacks directly using llamaindex-cli, which comes installed with the llama-index Python package:

pip install llama-index
llamaindex-cli download-llamapack PanelChatPack --download-dir ./panel_chat_pack

You can then inspect the files in the panel_chat_pack folder and use them as a template for your own project!

To run the app directly, use in your terminal:

export OPENAI_API_KEY="sk-..."
export GITHUB_TOKEN='...'
panel serve ./panel_chat_pack/base.py

As an alternative to panel serve, you can run

python ./panel_chat_pack/base.py

📈 Potential Improvements

• Improved Multi-user support
  • Loading queue: Users should not be able to download the same repository at the same time.
• Service Context
  • Enable users to define the service context including model, temperature etc.
• Better loading experience
  • Let the chat assistant show (more fine-grained) status messages. And provide more status changes
• Focus on the streaming text
  • The streaming text is not always in focus. I believe its a matter of adjusting the auto_scroll_limit limit.
• Fix minor CSS issues
  • See the CSS_FIXES_TO_BE_UPSTREAMED_TO_PANEL variable in the code
• Repo Manager
  • Support using multiple repos. For example the full HoloViz suite
