"""A script running `create_dummy_models.py` with a pre-defined set of arguments.

This file is intended to be used in a CI workflow file without the need of specifying arguments. It creates and uploads
tiny models for all model classes (if their tiny versions are not on the Hub yet), as well as produces an updated
version of `tests/utils/tiny_model_summary.json`. That updated file should be merged into the `main` branch of
`transformers` so the pipeline testing will use the latest created/updated tiny models.
