WebJul 11, 2024 · PS: This method is highly memory inefficient is kd-tree calculation possible using torch? Xiaotian_Liu (Xiaotian Liu) March 16, 2024, 2:25am 3 Hi amitoz, I think the torch_cluster has a function you can directly call to compute the knn graph of a given torch tensor. from torch_cluster import knn_graph graph = knn_graph (a,k,loop=False) WebThe KD tree is a binary tree structure which recursively partitions the parameter space along the data axes, dividing it into nested orthotropic regions into which data points are filed. The construction of a KD tree is …
