|---|
| الوصف | # Bug Description
Calling `unpack_sequence` on an empty PackedSequence leads to a segmentation fault.
# Reproduction Steps
Run the following code:
```
import torch
from torch.nn.utils.rnn import PackedSequence, unpack_sequence
empty_data = torch.tensor([])
empty_batch_sizes = torch.tensor([], dtype=torch.int64)
packed = PackedSequence(data=empty_data, batch_sizes=empty_batch_sizes)
unpack_sequence(packed)
```
# Observed Behavior
The program crashes with a segmentation fault, indicating an invalid memory access. |
