"""
For Gradio Spaces deployment:

1. Set environment variables in Space settings:
   - OPENAI_API_KEY: Your OpenAI API key
   - QDRANT_URL: URL to your cloud Qdrant instance
   - QDRANT_API_KEY: API key for cloud Qdrant (if required)

2. Consider using Qdrant Cloud or self-hosted Qdrant instance
   since Gradio Spaces don't support Docker containers

3. The app will show warning messages if components fail to initialize
   but will still launch for configuration troubleshooting
