Merge repeated labels into single labels.

tf.nn.collapse_repeated(
    labels, seq_length, name=None
)

Args:

• labels: Tensor of shape [batch, max value in seq_length]
• seq_length: Tensor of shape [batch], sequence length of each batch element.
• name: A name for this Op. Defaults to "collapse_repeated_labels".

Returns:

A tuple (collapsed_labels, new_seq_length) where

• collapsed_labels: Tensor of shape [batch, max_seq_length] with repeated labels collapsed and padded to max_seq_length, eg: [[A, A, B, B, A], [A, B, C, D, E]] => [[A, B, A, 0, 0], [A, B, C, D, E]]

• new_seq_length: int tensor of shape [batch] with new sequence lengths.
