Question

A team stores its models in Unity Catalog. A data scientist has just registered version 7 of the model 'main.ml.churn_model' and wants to promote it so that a downstream batch scoring job automatically picks up this new version without changing the job's code. The job loads the model using the URI 'models:/main.ml.churn_model@Champion'. What is the correct action to ensure the batch job uses version 7?

Accepted Answer

Assign the 'Champion' alias to version 7 of the model using MlflowClient.set_registered_model_alias().

Answer

Transition version 7 to the 'Production' stage using MlflowClient.transition_model_version_stage().

Answer

Re-register the model so version 7 automatically becomes the latest and is loaded by the '@Champion' URI.

Answer

Add a tag 'Champion=true' to version 7 with MlflowClient.set_model_version_tag().
