The Pusher component is used to push a validated model to a deployment target during model training or re-training. It relies on a Evaluator component to ensure that the new model is "good enough" to be pushed to production.
- Consumes: A Trained model in SavedModel format
- Emits: The same SavedModel, along with versioning metadata
Using the Pusher Component
A Pusher pipeline component is typically very easy to deploy and requires little customization, since all of the work is done by the Pusher TFX component. Typical code looks like this:
from tfx import components
...
pusher = components.Pusher(
model=trainer.outputs['model'],
model_blessing=model_validator.outputs['blessing'],
push_destination=pusher_pb2.PushDestination(
filesystem=pusher_pb2.PushDestination.Filesystem(
base_directory=serving_model_dir)
)
)
