<pre>
Static mapping between the index and display name.

Use this if the outputs are a deterministic n-dimensional array, e.g. a
list of scores of all the classes in a pre-defined order for a
multi-classification Model. It's not feasible if the outputs are
non-deterministic, e.g. the Model produces top-k classes or sort the
outputs by their values.

The shape of the value must be an n-dimensional array of strings. The
number of dimensions must match that of the outputs to be explained.
The
[Attribution.output_display_name][google.cloud.aiplatform.v1.Attribution.output_display_name]
is populated by locating in the mapping with
[Attribution.output_index][google.cloud.aiplatform.v1.Attribution.output_index].
