Calculates the full beams for TensorArrays.

Aliases:

• tfa.seq2seq.beam_search_decoder.gather_tree_from_array

tfa.seq2seq.gather_tree_from_array(
    t,
    parent_ids,
    sequence_length
)

Args:

• t: A stacked TensorArray of size max_time that contains Tensors of shape [batch_size, beam_width, s] or [batch_size * beam_width, s] where s is the depth shape.
• parent_ids: The parent ids of shape [max_time, batch_size, beam_width].
• sequence_length: The sequence length of shape [batch_size, beam_width].

Returns:

A Tensor which is a stacked TensorArray of the same size and type as t and where beams are sorted in each Tensor according to parent_ids.
