`scipy.spatial._ckdtree:cKDTree._build_weights`

Signature

def _build_weights ( weights )

Summary

Compute weights of nodes from weights of data points. This will sum up the total weight per node. This function is used internally.

Parameters

weights : array_like: weights of data points; must be the same length as the data points. currently only scalar weights are supported. Therefore the weights array must be 1 dimensional.

Returns

node_weights : array_like: total weight for each KD-Tree node.
