For more information on how to use this operator, take a look at the guide: Making predictions

NOTE: For model origin, users should consider exactly one from the three options below:

Populate uri field only, which should be a GCS location that points to a tensorflow savedModel directory.
Populate model_name field only, which refers to an existing model, and the default version of the model will be used.
Populate both model_name and version_name fields, which refers to a specific version of a specific model.

In options 2 and 3, both model and version name should contain the minimal identifier. For instance, call:

MLEngineBatchPredictionOperator(
    ...,
    model_name='my_model',
    version_name='my_version',
    ...)

if the desired model version is projects/my_project/models/my_model/versions/my_version.

See https://cloud.google.com/ml-engine/reference/rest/v1/projects.jobs for further documentation on the parameters.

Parameters
