Used in the tutorials

The Pusher component can be used to push an validated SavedModel from output of the Trainer component to TensorFlow Serving. The Pusher will check the validation results from the Evaluator component and InfraValidator component before deploying the model. If the model has not been blessed, then the model will not be pushed.


  # Checks whether the model passed the validation steps and pushes the model
  # to a file destination if check passed.
