A component that binds a DataView to ExamplesArtifact.

Inherits From: BaseComponent, BaseNode

tfx.components.experimental.data_view.binder_component.DataViewBinder(
    input_examples: tfx.types.Channel,
    data_view: tfx.types.Channel,
    output_examples: Optional[tfx.types.Channel] = None
)

It takes as inputs a channel of Examples and a channel of DataView, and binds the DataView (i.e. attaching information from the DataView as custom properties) to the Examples in the input channel, producing new Examples Artifacts that are identical to the input Examples (including the uris), except for the additional information attached.

Example:

  # We assume Examples are imported by ExampleGen
  example_gen = ...
  # First, create a dataview:
  data_view_provider = TfGraphDataViewProvider(
      module_file=module_file,
      create_decoder_func='create_decoder')
  # Then, bind the DataView to Examples:
  data_view_binder = DataViewBinder(
      input_examples=example_gen.outputs['examples'],
      data_view=data_view_provider.outputs['data_view'],
      )
  # Downstream component can then consume the output of the DataViewBinder:
  stats_gen = StatisticsGen(
      examples=data_view_binder.outputs['output_examples'], ...)
