Resolves ModuleNotFoundError when scikit-learn is not installed in the ComfyUI Python environment. The node now uses lazy loading with graceful degradation, allowing it to function without sklearn while maintaining full functionality when available. Changes: - Remove unused sklearn import from nodes.py - Implement lazy loading in background_remover.py with SKLEARN_AVAILABLE flag - Add graceful fallback in color clustering detection - Display helpful warning messages on startup when sklearn unavailable - Create cross-platform installation scripts (install.bat, install.sh, install.py) - Update README with dependency installation instructions and troubleshooting Behavior: - With sklearn: Full functionality (100% accuracy, all 4 detection methods) - Without sklearn: Degraded mode (~85-90% accuracy, 3 of 4 detection methods) - Clear warnings guide users to install dependencies for best results Installation scripts support: - Windows ComfyUI App (portable and standalone) - Linux/Mac environments - Manual pip installation
