Output only.
The ID of the annotation spec that the model evaluation applies to. The
The ID is empty for the overall model evaluation.
For Tables classification these are the distinct values of the target
column at the moment of the evaluation; for this problem annotation specs
in the dataset do not exist.
NOTE: Currently there is no way to obtain the display_name of the
annotation spec from its ID. To see the display_names, review the model
evaluations in the UI.
