Check the duplicated edges in the graph

[guanshaoheng]

🚀 The feature, motivation and pitch

Before removing duplicate edges, we can use this function to extract and inspect all the duplicates. This is particularly useful for designing the graph network and for debugging, as edges can easily become duplicated when selected by nodes. In calculations, these duplicate edges can impact the network’s predictions…

maybe making some modifications to the function torch_geometric.utils.coalesce can work

[rachitk]

There is a transform RemoveDuplicatedEdges that should in theory do this - is there additional functionality that you'd need?

As you mentioned, the transform just calls coalesce: https://pytorch-geometric.readthedocs.io/en/latest/modules/utils.html#torch_geometric.utils.coalesce
