Fix DuplicateModelException

✅ Solution

The DuplicateModelException in InvokeAI arises when attempting to save different models or model variants to the same destination file path, often during starter model installation or custom model import processes. To resolve this, ensure each model is assigned a unique name and that the destination paths specified for saving models (filenames) are distinct, preventing write conflicts and allowing successful model storage. Double check for name clashes in your models.yaml file, renaming as needed.
