When does this happen?

IF Loading a custom model from a second local save location fails with ValueError due to incomplete 'auto_map' entries in config.json.

How others solved it

THEN Upgrade transformers to a version containing PR #37716 (e.g., >=4.45.x? but check changelog) which saves the code alongside the model instead of remote references. Alternatively, manually add the missing repo prefix (e.g., 'repo_id--') to the 'AutoConfig' value in the config's auto_map. A workaround is to add '_auto_class' to config, but the PR fix is recommended.

# After saving model to temp_dir1 and loading, saving to temp_dir2 and loading fails.
# Fix: ensure config.json auto_map has full prefix, e.g.,
# "AutoConfig": "Alibaba-NLP/new-impl--configuration.NewConfig"
