tf.compat.v1.ragged.placeholder

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
)

Key Point: 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
