SnapshotDataset

public final class SnapshotDataset

Creates a dataset that will write to / read from a snapshot.

This dataset attempts to determine whether a valid snapshot exists at the `snapshot_path`, and reads from the snapshot in lieu of using `input_dataset`. If not, it will run the preprocessing pipeline as usual, and write out a snapshot of the data processed for future use.

Inherited Methods

Public Methods

public Output <Object> asOutput ()

Returns the symbolic handle of a tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

public static SnapshotDataset.Options compression (String compression)

public static SnapshotDataset create ( Scope scope, Operand <?> inputDataset, Operand <String> path, List<Class<?>> outputTypes, List< Shape > outputShapes, Options... options)

Factory method to create a class wrapping a new SnapshotDataset operation.

Parameters
scope current scope
inputDataset A variant tensor representing the input dataset.
path The path we should write snapshots to / read snapshots from.
options carries optional attributes values
Returns
  • a new instance of SnapshotDataset
