tile_batch(
    t,
    multiplier,
    name=None
)

Defined in tensorflow/contrib/seq2seq/python/ops/beam_search_decoder.py.

Tile the batch dimension of a (possibly nested structure of) tensor(s) t.

For each tensor t in a (possibly nested structure) of tensors, this function takes a tensor t shaped [batch_size, s0, s1, ...] composed of minibatch entries t[0], ..., t[batch_size - 1] and tiles it to have a shape [batch_size * multiplier, s0, s1, ...] composed of minibatch entries t[0], t[0], ..., t[1], t[1], ... where each minibatch entry is repeated multiplier times.

Args:

• t: Tensor shaped [batch_size, ...].
• multiplier: Python int.
• name: Name scope for any created operations.

Returns:

A (possibly nested structure of) Tensor shaped [batch_size * multiplier, ...].

Raises:

• ValueError: if tensor(s) t do not have a statically known rank or the rank is < 1.
