tf.compat.v1.ragged.placeholder

View source on GitHub

Creates a placeholder for a tf.RaggedTensor that will always be fed.

tf.compat.v1.ragged.placeholder(
    dtype,
    ragged_rank,
    value_shape=None,
    name=None
)

Important: This ragged tensor will produce an error if evaluated. Its value must be fed using the feed_dict optional argument to Session.run(), Tensor.eval(), or Operation.run().

@compatibility{eager} Placeholders are not compatible with eager execution.

Args:

  • dtype: The data type for the RaggedTensor.
  • ragged_rank: The ragged rank for the RaggedTensor
  • value_shape: The shape for individual flat values in the RaggedTensor.
  • name: A name for the operation (optional).

Returns:

A RaggedTensor that may be used as a handle for feeding a value, but not evaluated directly.

Raises:

  • RuntimeError: if eager execution is enabled
