# GATE Motion Analysis - Gradio Deployment

## ✅ Error Fixes Applied

This deployment addresses the following errors that were encountered:

### 1. Browser Feature Policy Warnings (Fixed)
- **Error**: `Unrecognized feature: 'ambient-light-sensor'`, `'battery'`, etc.
- **Fix**: Added `analytics_enabled=False` to disable Google Analytics tracking that causes these warnings

### 2. Font Loading Issues (Fixed)
- **Error**: `ui-sans-serif-Regular.woff2:1 Failed to load resource: 404`
- **Fix**: Set `favicon_path=None` and removed custom font dependencies

### 3. API Errors (Fixed)
- **Error**: `Submit function encountered an error: Error: No API found`
- **Fix**: 
  - Simplified interface with proper Gradio component setup
  - Disabled API documentation (`show_api=False`)
  - Added proper error handling and fallback configurations

### 4. JavaScript Errors (Fixed)
- **Error**: `MutationObserver: parameter 1 is not of type 'Node'`
- **Fix**: Removed complex dependencies and iframe conflicts

## 🚀 Quick Start

### Local Development
```bash
cd gradio_deployment
pip install -r requirements.txt
python app.py
```

### HuggingFace Spaces Deployment
1. Upload all files in `gradio_deployment/` folder to your Space
2. Set the following environment variables (optional):
   - `DEBUG_MODE=true` for verbose logging
   - `USE_GPU=true` if GPU is available

## 📋 Features

- **Image Analysis**: Upload exercise photos for form analysis
- **Video Analysis**: Upload exercise videos (processes first frame)
- **Multiple Exercises**: Support for squats, push-ups, lunges, bicep curls, deadlifts
- **Real-time Feedback**: Instant form scoring and recommendations
- **System Monitoring**: Built-in system status and debugging tools

## 🛠️ Configuration

The deployment is configured via `config.py`:

- **Performance**: Limited to 4 threads and 10 concurrent users
- **File Limits**: Maximum 50MB upload size
- **Security**: CORS enabled, SSL verification disabled for development
- **UI Theme**: Soft theme with custom CSS styling

## 📱 Usage

1. **Select Analysis Type**: Choose between Image or Video analysis
2. **Upload File**: Drag and drop or click to upload exercise media
3. **Select Exercise**: Choose the exercise type from dropdown
4. **View Results**: See analyzed image with confidence score and feedback

## 🔧 Technical Details

### Dependencies
- **Gradio 4.0+**: Web interface framework
- **OpenCV**: Image/video processing (headless version for deployment)
- **NumPy**: Numerical computations
- **Pillow**: Image handling

### Architecture
- **Simplified Design**: Removed complex ML dependencies for stability
- **Error Resilience**: Comprehensive error handling and fallbacks
- **Resource Management**: Memory and thread limits for shared environments

## 🐛 Troubleshooting

### Common Issues

1. **Import Errors**
   - All complex dependencies removed
   - Self-contained deployment with minimal requirements

2. **API Connection Issues**
   - Added fallback launch configuration
   - Disabled problematic features (share, API docs)

3. **Performance Issues**
   - Enabled queuing system
   - Limited concurrent users and threads

### Debug Mode
Enable debug mode by setting `DEBUG_MODE=true` environment variable for detailed logging.

## 📝 Notes

- This is a **demonstration version** focused on deployment stability
- For full ML functionality, additional models and dependencies would be required
- The current version provides mock analysis results to ensure interface functionality
- All reported browser and API errors have been addressed

## 🔄 Changelog

### Version 2.0.0
- ✅ Fixed all reported Gradio deployment errors
- ✅ Simplified dependencies and removed complex imports
- ✅ Added comprehensive error handling
- ✅ Optimized for HuggingFace Spaces deployment
- ✅ Improved UI with proper CSS and theming

## Quick Deployment

### Option 1: Gradio Deploy (Recommended)

```bash
# From this directory
gradio deploy

# Follow the prompts to deploy to Hugging Face Spaces
```

### Option 2: Local Testing

```bash
# Install dependencies
pip install -r requirements.txt

# Run locally
python app.py
```

## Performance Optimisations

- **GPU Memory Management**: Configured for shared GPU environments
- **Model Selection**: Uses lightweight fallback models for faster inference
- **Streaming Settings**: Optimised for 30 FPS real-time analysis
- **Thread Limiting**: Prevents resource exhaustion on shared hardware

## Features

- Real-time pose detection with skeleton overlay
- Motion similarity analysis using BPE (Body Part Embedding)
- British English interface without emoji distractions
- GPU acceleration for YOLOv8 pose detection
- Fallback to MediaPipe for CPU environments

## Deployment Requirements

- **GPU**: CUDA-compatible GPU with 4GB+ VRAM recommended
- **CPU**: 4+ cores for fallback mode
- **RAM**: 8GB+ system memory
- **Python**: 3.8+ with pip

## Configuration

The app automatically detects available hardware and optimises accordingly:

- **GPU Available**: Uses YOLOv8 for high-performance pose detection
- **CPU Only**: Falls back to MediaPipe for stable operation

## Troubleshooting

1. **GPU Memory Issues**: Reduce batch size or use CPU fallback
2. **Import Errors**: Ensure all dependencies are installed
3. **Performance Issues**: Check CUDA installation and GPU memory

## Security

- API endpoints disabled for public deployment
- File access restricted to safe directories
- No authentication required for demo purposes

## GPU Requirements

- **Minimum**: 4GB VRAM
- **Recommended**: 8GB+ VRAM (RTX 3070 or better)
- **Optimal**: 16GB+ VRAM (RTX 4080/4090)

## Browser Compatibility

- Chrome 88+ (recommended)
- Firefox 85+
- Safari 14+
- Edge 88+

## Deployment Notes

When deploying to Hugging Face Spaces:
1. Select GPU (T4 or better) for optimal performance
2. Enable persistence for model caching
3. Set timeout to 30+ minutes for complex analyses
