Non-finite matrix entry about hsn HOT 1 OPEN

I wouldn't know what would be the exact issue. What might help to debug is to check your dataset in the vector heat demo project. This way, you can visually see what's going on. If that fails, you could also try a different way to compute nearest neighbours: https://pytorch-geometric.readthedocs.io/en/latest/modules/nn.html?highlight=nearest#torch_geometric.nn.pool.nearest

The difference between PyTorch Geometric's nearest neighbours, is that it is computed in R3, whereas the nearest neighbours used by us is computed intrinsically (with geodesic distances). Depending on the shape and distances this doesn't have to be a major problem.
