Questions about the radius_graph

[XindongChen]

When my node pos.shape is [1900, 3], to cacluate edge_index with radius_graph, I found some edges should exist, but radius_graph does not return them. Then, I exact these corresponding node coordinates to make a smaller node slice, node pos.shape is [200, 3], now the radius_graph can return all the edges that should exist. In the two cases, the cutoff distance is alway the same value. Does anyone encounter the same problem with radius_graph whe the node number in a graph is large?
