If you're trying to train your own Personal Edit Style and it fails, double check the following things:
Reduce the Number of Images:
Attempt training with fewer images. We recommend using less than 16,000 images. If issues persist, try an even smaller batch, such as 3000.
Catalog Storage:
If your catalog is stored on a network drive (NAS), it must first be copied onto your computer or an external drive.
If you're using a cloud based storage system such as iCloud or OneDrive, ensure that you have all the files related to your catalog downloaded to your computer.
Allowing Permissions for Narrative:
Ensure you have allowed all permissions for Narrative, you can do this by going to System Settings -> Privacy and Security -> Files and Folders:
Update Narrative:
Ensure that Narrative is up to date, you can do this by clicking 'Narrative Select' in the menu bar, then 'Check for Updates'.
