I am getting a confusing error that I’m not sure why is occurring. This is the error I am getting:

```
torch.Size([24047])
tensor([1315, 1318, 1472, 1454, 1318, 1337, 1453, 1454, 1317, 1310])
Traceback (most recent call last):
...
deg_inv = deg.pow(-1)
RuntimeError: Integers to negative integer powers are not allowed.
```

And this is part of the code:

```
from torch_scatter import scatter_add
from torch_geometric.utils import add_remaining_self_loops, add_self_loops, remove_self_loops
...
if edge_weight ==None:
edge_weight = torch.ones((edge_index.size(1), ), dtype=dtype,
device=edge_index.device)
fill_value = 1
edge_index, edge_weight = add_self_loops(
edge_index, edge_weight, fill_value, num_nodes)
row, col = edge_index
deg = scatter_add(edge_weight, row, dim=0, dim_size=num_nodes)
print(deg.size())
print(deg[:10])
deg_inv = deg.pow(-1)
```

I have not found anything related to this online. I’m not sure why this would be occurring?
