Explanation configuration for this DeployedModel.

When deploying a Model using
[EndpointService.DeployModel][google.cloud.aiplatform.v1.EndpointService.DeployModel],
this value overrides the value of
[Model.explanation_spec][google.cloud.aiplatform.v1.Model.explanation_spec].
All fields of
[explanation_spec][google.cloud.aiplatform.v1.DeployedModel.explanation_spec]
are optional in the request. If a field of
[explanation_spec][google.cloud.aiplatform.v1.DeployedModel.explanation_spec]
is not populated, the value of the same field of
[Model.explanation_spec][google.cloud.aiplatform.v1.Model.explanation_spec]
is inherited. If the corresponding
[Model.explanation_spec][google.cloud.aiplatform.v1.Model.explanation_spec]
is not populated, all fields of the
[explanation_spec][google.cloud.aiplatform.v1.DeployedModel.explanation_spec]
will be used for the explanation configuration.
