torch.nested.as_nested_tensor fails with tensor on device #129647
Description
🐛 Describe the bug
torch.nested.as_nested_tensor fails with tensor on device, works with tensor on CPU:
>>> a = torch.ones( 10, 5, 16)
>>> b = torch.nested.as_nested_tensor( a, layout=torch.jagged)
>>> a = torch.ones( 10, 5, 16, device='cuda')
>>> b = torch.nested.as_nested_tensor( a, layout=torch.jagged)
