If populated, only returns attributions that have
[output_index][google.cloud.aiplatform.v1.Attribution.output_index]
contained in output_indices. It must be an ndarray of integers, with the
same shape of the output it's explaining.

If not populated, returns attributions for
[top_k][google.cloud.aiplatform.v1.ExplanationParameters.top_k] indices of
outputs. If neither top_k nor output_indices is populated, returns the
argmax index of the outputs.

Only applicable to Models that predict multiple outputs (e,g, multi-class
Models that predict multiple classes).
