# tensorplay.nn.utils.rnn.unpack_sequence

Source: https://www.tensorplay.cn/docs/generated/tensorplay.nn.utils.rnn.unpack_sequence.html

```python
tensorplay.nn.utils.rnn.unpack_sequence(packed_sequences: PackedSequence)
```

Unpack PackedSequence into a list of variable length Tensors.

packed_sequences should be a PackedSequence object.

Example

```
>>> from tensorplay.nn.utils.rnn import pack_sequence, unpack_sequence
>>> a = tp.tensor([1, 2, 3])
>>> b = tp.tensor([4, 5])
>>> c = tp.tensor([6])
>>> sequences = [a, b, c]
>>> packed_sequences = pack_sequence(sequences)
>>> unpacked_sequences = unpack_sequence(packed_sequences)
```

Parameters:

packed_sequences ([PackedSequence](/docs/generated/tensorplay.nn.utils.rnn.PackedSequence.html#tensorplay.nn.utils.rnn.PackedSequence)) – A PackedSequence object.

Returns:

a list of Tensor objects
