-      Please provide a clear and concise description of the bug.

-      If relevant, add a minimal example so that we can reproduce the error by running the code. It is very important for the snippet to be as minimal as possible, so please take time to trim down any irrelevant code to help us debug efficiently. We are going to copy-paste your code and we expect to get the same result as you did: avoid any external data, and include the relevant imports:
-
-      ```python
-      # All necessary imports at the beginning
-      import torch
-      from torch_geometric.utils import to_undirected

-      # A minimal reproducing example trimmed down to the essential parts:
-      edge_index = torch.tensor([[0, 1, 2], [1, 2, 3]])

-      assert edge_index.size(1) == 6  # We expect that the number of edges is doubled.
-
-      # NOTE: the bug is that num_nodes < edge_index.max() + 1
