🎯 Access the System

Gradio UI (Currently Running)

URL: http://localhost:7860

The Gradio interface is already running in your cascade terminal!

Features:

• 🔍 Single vehicle diagnostics
• 📊 Vehicle overview with anomaly list
• 📋 Full diagnostic reports
• 📈 Interactive visualizations

---

🔧 Running Different Components

1. Gradio UI (Interactive Dashboard)

# If not already running:
python src/ui/gradio_app.py

# Or use the quick start script:
./run_ui.sh

2. FastAPI Backend (REST API)

# Start the API server:
uvicorn src.api.main:app --host 0.0.0.0 --port 8000 --reload

# Or use the quick start script:
./run_api.sh

API Endpoints:

• http://localhost:8000 - Root
• http://localhost:8000/docs - Interactive API documentation
• http://localhost:8000/health - Health check
• http://localhost:8000/vehicles - List vehicles
• http://localhost:8000/diagnose - Run diagnostic

3. Python Script (Direct)

# Run the demo script:
python demo.py

# Or test the orchestrator:
python src/orchestrator.py

4. Docker (Production Deployment)

# Build and run with Docker Compose:
docker-compose up --build

# Access:
# - API: http://localhost:8000
# - UI: http://localhost:7860

📝 Quick Examples

Example 1: Using Gradio UI

1. Open http://localhost:7860 in your browser
2. Go to "Single Vehicle Diagnostic" tab
3. Select a vehicle ID from the dropdown
4. Set number of readings (e.g., 200)
5. Click "Run Diagnostic"
6. View results, visualizations, and full report

Example 2: Using Python API

from src.orchestrator import VehicleDiagnosticOrchestrator

# Initialize
orchestrator = VehicleDiagnosticOrchestrator()

# Run diagnostic
result = orchestrator.diagnose_vehicle(vehicle_id=32, n_readings=200)

# Access results
if result['success']:
    print(result['report']['natural_language_summary'])
    print(f"Anomaly Score: {result['anomaly_result']['overall_score']}")

Example 3: Using REST API

# Health check
curl http://localhost:8000/health

# List vehicles
curl http://localhost:8000/vehicles

# Run diagnostic
curl -X POST http://localhost:8000/diagnose \
  -H "Content-Type: application/json" \
  -d '{"vehicle_id": 32, "n_readings": 200}'

# Get full report
curl http://localhost:8000/report/32

📊 Sample Vehicles to Try

Based on the test data, here are some interesting vehicles:

Vehicles with Anomalies:

• Vehicle 32: High anomaly rate (~75%), cooling system issues
• Vehicle 8: Medium anomaly rate, multiple sensor issues
• Vehicle 15: Low anomaly rate, tire pressure issues

Healthy Vehicles:

• Vehicle 1: No anomalies detected
• Vehicle 2: Clean sensor readings
• Vehicle 5: Normal operation

🔍 Troubleshooting

Issue: Gradio UI not loading

Solution: Check if the UI is already running in another terminal. Only one instance can run on port 7860.

Issue: Model not found error

Solution: Train the model first:

python src/models/train_anomaly_detector.py

Issue: Data not found error

Solution: Generate and preprocess data:

python src/utils/download_data.py
python src/utils/data_preprocessing.py

Issue: Import errors

Solution: Make sure vda conda environment is activated:

conda activate vda

Issue: Port already in use

Solution: Change the port or stop the existing process:

# For Gradio (default 7860):
python src/ui/gradio_app.py  # Will auto-select next available port

# For FastAPI (default 8000):
uvicorn src.api.main:app --port 8001

🎯 Next Steps

1. Explore the Gradio UI - Try diagnosing different vehicles
2. Test the API - Use the FastAPI docs at /docs
3. Run the demo - Execute python demo.py
4. Customize - Modify agents for your use case
5. Deploy - Use Docker for production deployment
