📌 Key Model Loading Strategy

The app uses an intelligent fallback chain for maximum reliability:

1. Models/effBb3/best_phase2.keras     ← PRIMARY (ACTIVE)
   ↓
2. Models/effBb3/skin_disease_model.keras
   ↓
3. Models/effBb3/best_phase1.keras
   ↓
4. Legacy output folder backups        ← FALLBACK

✨ Auto-skips incompatible models (mixed_float16 issues)

🐛 Troubleshooting

Common Issues & Solutions

Issue: "Model not found" error

Solution: Ensure all model files exist in Models/effBb3/ directory. Run:

ls Models/effBb3/

Issue: Port 5000 already in use

Solution: Change the port in app.py or kill the process:

# macOS/Linux
lsof -i :5000 | grep LISTEN | awk '{print $2}' | xargs kill

# Windows
netstat -ano | findstr :5000
taskkill /PID <PID> /F

Issue: Camera permission denied

Solution: Check browser camera permissions:

1. Click the camera icon in address bar
2. Select "Allow" for camera access
3. Refresh the page

Issue: Slow predictions on CPU

Solution: Install GPU drivers or upgrade hardware. CPU inference takes 200-500ms depending on specs.

Issue: Out of Memory error

Solution: Close other applications or reduce batch size. GPU memory issues? Check CUDA availability:

python -c "import tensorflow as tf; print(tf.config.list_physical_devices('GPU'))"

Issue: Image upload fails

Solution: Check file format (JPEG, PNG, WebP, BMP) and size (<16MB). Verify permissions:

chmod 755 uploads/  # Linux/macOS

❓ FAQ

Frequently Asked Questions

Q: Can this replace a dermatologist? A: Absolutely not. This is an educational tool only. Always consult healthcare professionals for medical decisions.

Q: What diseases can it detect? A: 30 common skin conditions. Check data/disease_info.json for the complete list.

Q: How accurate is the model? A: Typical accuracy is 85-92% on test data, but real-world accuracy varies. Always verify with medical professionals.

Q: Can I use my own model? A: Yes! Replace files in Models/effBb3/ with your .keras or .h5 files. Update preprocessing in app.py if needed.

Q: How do I deploy this? A: Use Docker:

docker build -t skin-disease-detector .
docker run -p 5000:5000 skin-disease-detector

Or deploy to cloud (AWS, Azure, GCP, Heroku).

Q: Can I use this commercially? A: No. MIT license permits personal/educational use only. Contact author for commercial licensing.

Q: How do I improve accuracy? A: Retrain with more diverse data. See training notebooks for implementation details.

Q: Is the model open source? A: Model weights are included. Training code is in notebooks. Architecture details are in docstrings.

Q: Why does prediction take so long? A: Check system specs. GPU inference: 50-100ms. CPU: 200-500ms. SSD is much faster than HDD.
