 3. **Add Nested Parameters**  
    If needed, create nested parameters using `CN()`:
    ```python
    cfg.model.next = CN()
    cfg.model.next.default = 1
-```
+   ```
 
 4. **Sync Parameters Across Configs**  
    Ensure the parameters in `cfg_model` align with those in other configs (e.g., `cfg_trafficflow`) to avoid compatibility issues across systems (Windows, Linux, etc.).
