Practice - 5 Tasks

1fill in blank

easy

Complete the code to promote a model to the 'Staging' stage using MLflow.

MLOps

mlflow_client.transition_model_version_stage(name='my_model', version=[1], stage='Staging')

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using stage names instead of version number

Using strings like 'latest' instead of version number

The version parameter expects the model version number as an integer or string. Here, 1 is the correct version number to promote.

Complete the code to check the current stage of a model version.

MLOps

model_version = mlflow_client.get_model_version(name='my_model', version=[1])
current_stage = model_version.[2]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using attribute names instead of version number

Using stage names instead of version number

The version parameter must be the model version number, here 1. The current stage is accessed via model_version.stage.

Fix the error in the code to promote a model version to 'Production' stage.

MLOps

mlflow_client.transition_model_version_stage(name='my_model', version=2, stage=[1])

Drag options to blanks, or click blank then click option'

A'Production'

B'staging'

C'production'

Dproduction

💡 Hint

Common Mistakes

Using lowercase 'production'

Using unquoted stage names

The stage name must be a title case string exactly matching MLflow's expected stage names. Use 'Production' with capital 'P'.

4fill in blank

hard

Fill both blanks to create a dictionary mapping model versions to their stages.

MLOps

version_stage_map = {mv.version: mv.[1] for mv in mlflow_client.search_model_versions('name="my_model"') if mv.[2] != 'Archived'}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'status' instead of 'stage'

Using 'version' instead of 'stage'

The attribute stage holds the stage name of the model version. We use it both to get the stage and to filter out 'Archived' versions.

hard

Fill all three blanks to promote all 'Staging' models to 'Production' stage.

MLOps

for mv in mlflow_client.search_model_versions('name="my_model"'):
    if mv.[1] == '[2]':
        mlflow_client.transition_model_version_stage(name='my_model', version=mv.[3], stage='Production')

💡 Hint

Common Mistakes

Using 'status' instead of 'stage'

Using 'stage' as version

Using unquoted stage names

We check the stage attribute to find models in 'Staging'. Then we use the version attribute to promote each model to 'Production'.
