| विवरण | # Bug Description
Calling pad_packed_sequence on an empty PackedSequence leads to a segmentation fault.
# Reproduction Steps
Run the following code:
```
import torch
from torch.nn.utils.rnn import pad_packed_sequence, PackedSequence
empty_data = torch.randn(0, 5)
empty_batch_sizes = torch.tensor([], dtype=torch.int64)
empty_packed = PackedSequence(empty_data, empty_batch_sizes, None, None)
# Causes segmentation fault
pad_packed_sequence(empty_packed, batch_first=True)
```
# Observed Behavior
The program crashes with a segmentation fault, indicating an invalid memory access. |
