Run the deployment preparation script: + + **For Windows:** + ``` + prepare_deployment.bat + ``` + + **For Linux/Mac:** + ``` + chmod +x prepare_deployment.sh + ./prepare_deployment.sh + ``` + +2. Build the Docker container: + ``` + docker build -t marine-pollution-api . + ``` + +3. Run the container: + ``` + docker run -p 7860:7860 marine-pollution-api + ``` + +### Option 2: Manual Deployment + +1. Clean up unnecessary files: + - Remove all test files (`test_*.py`, `test_files/`, `test_output/`, etc.) + - Remove smaller YOLO models (keep only `yolov8x.pt`) + - Remove development utilities (`debug_*.py`, etc.) + +2. Use the production Dockerfile: + ``` + cp Dockerfile.prod Dockerfile + cp .dockerignore.prod .dockerignore + ``` + +3. Build and run the Docker container as described in Option 1. + +## Important Notes + +1. **YOLOv8x Model**: The system now exclusively uses YOLOv8x (the largest/most accurate model) for marine pollution detection. The model file will be downloaded automatically on the first run if it doesn't exist. + +2. **Image Annotation**: The output images now have more subtle scene annotations in small text to improve readability. + +3. **Deployment Size**: The Docker image is optimized to include only necessary files for production use. + +4. **First Run**: The first time the system runs, it will download the YOLOv8x model (approximately 136MB). Subsequent runs will use the downloaded model. + +5. **Requirements**: Make sure the deployment environment has sufficient memory and processing power to run YOLOv8x effectively. + +## Troubleshooting + +1. **Model Download Issues**: If the model download fails, check your internet connection. If you want to manually provide the YOLOv8x model, place the file in the root directory of the project. + +2. **Performance Optimization**: For better performance on low-resource environments, consider adding memory management optimizations or serving the model with ONNX Runtime. + +3. **Errors**: Check the logs for detailed error messages.
