    2. Check that the model is correctly created:
-      - Static validation of the model format using the [bioimageio.core python library](https://github.com/bioimage-io/core-bioimage-io-python) library (*e.g.*, in the terminal, `python bioimageio validate /../rdf.yaml`).
-      - Dynamic validation of the model's deployment (*e.g.*, in the terminal, `python test_model --weights tensorflow_saved_model_bundle --device cpu /.../rdf.yaml`). It tests that the model generates the expected output.
