Initialize a Neptune model version by passing the ID of an existing version:
How do I find the ID?
The Neptune ID is a unique identifier for the object. It's shown in the leftmost column of the table view.
The ID is stored in the system namespace, in the
Pass the desired stage to the

This method is synchronous, which means that the stage is changed as soon as the line is executed.
To stop the connection to Neptune and sync all data, call the
stop()method and execute the script or cell:
Conditionally changing the model stage#
You can make the stage transition conditional by fetching some relevant metadata from the model version and checking the value.
The following code snippet fetches an accuracy value from the metrics logged for the model version, then compares it against a threshold of 0.9 before making the change:
