public final class TensorFlowNativeModel<T extends Output<T>>
extends TensorFlowModel<T>

This model encapsulates a TensorFlow model running in graph mode with a single tensor output.

It accepts an FeatureConverter that converts an example's features into a set of Tensors, and an OutputConverter that converts a Tensor into a Prediction.

This model's serialized form stores the weights and is entirely self contained. If you wish to convert it into a model which uses checkpoints then call convertToCheckpointModel(java.lang.String, java.lang.String).

The model's serialVersionUID is set to the major TensorFlow version number times 100.

N.B. TensorFlow support is experimental and may change without a major version bump.

Method Detail

copy

protected TensorFlowNativeModel<T> copy(String newName,
                                        ModelProvenance newProvenance)

Description copied from class: Model

Copies a model, replacing it's provenance and name with the supplied values.

Used to provide the provenance removal functionality.

Specified by:

copy in class Model<T extends Output<T>>

Parameters:

newName - The new name.

newProvenance - The new provenance.

Returns:

A copy of the model.

convertToCheckpointModel

public TensorFlowCheckpointModel<T> convertToCheckpointModel(String checkpointDirectory,
                                                             String checkpointName)

Creates a TensorFlowCheckpointModel version of this model.

Parameters:

checkpointDirectory - The directory to write the checkpoint to.

checkpointName - The name of the checkpoint files.

Returns:

A version of this model using a TensorFlow checkpoint to store the parameters.
