It is an inverse operation to :func:`pack_padded_sequence`.
The returned Variable's data will be of size TxBx*, where T is the length
- of the longest sequence and B is the batch size. If ``batch_size`` is True,
+ of the longest sequence and B is the batch size. If ``batch_first`` is True,
the data will be transposed into BxTx* format.
Batch elements will be ordered decreasingly by their length.
