🌐 Deployment

To deploy on Streamlit Community Cloud:

1. Create a new repository on GitHub
2. Add all project files
3. Go to Streamlit Community Cloud
4. Click "New app" and connect your repository
5. Set deployment branch to main
6. Set main file path to car_app.py
7. Click "Deploy!"

🔧 Customization

• Image: Replace car_image.jpg with your own image (recommended size: 1200x600px)
• Model: Replace final_model_XGBoost.pkl with your retrained model
• Styling: Modify CSS in the st.markdown() sections
• Features: Update COMPANY_MAPPING and encoding dictionaries as needed

🚨 Troubleshooting

Common errors and solutions:

1. Missing Model File:

   • Ensure final_model_XGBoost.pkl exists in project root
   • Verify model loading code matches training environment

2. Library Version Conflicts:

pip install --force-reinstall xgboost==1.7.3  # Use specific version

3. Image Not Loading:

   • Check image path and file permissions
   • Verify image format (JPEG/PNG)

4. Prediction Errors:

   • Confirm input values match training data ranges
   • Verify all dropdown selections have valid mappings
