I don’t thinks it’s possible : the checkpoints are output models, and such can be accessed from the task, but from the model class I can get only the url of the last version (as I expected from using update weights, as it does sound like it replaces the old weights with the new ones). Also, even if I could get the urls of the old checkpoints, how can I delete them from the file server? StorageManager doesn’t seem to have any method to delete remote files
