Kiddo Python Bindings

Barebones python bindings for the kiddo library.

You will probably want to change and recompile if you want to use it.

As of now, only f32 2D trees are supported, because that's what I need. You can change it to 3D/4D/AnyD.

Usage

git clone https://github.com/awarebayes/Kiddo-Python-Bindings
maturin develop --release

Or simply

pip install kiddo-python-bindings

Make sure your data is in float32 before passing it to functions

import kiddo_python_bindings as kpb
import numpy as np

a = np.random.randn(10, 2).astype(np.float32)
tree = kpb.Py2KDTree(a)
zero = np.array([0, 0], dtype=np.float32)
closest = tree.nearest_n_within(zero, 2.0, max_neighbours=10, sorted=True)
within = tree.within(zero, 2.0)
num_close = tree.count_within(zero, 2.0)
print("Closest", closest)
print("Within", within)
print("Num close", num_close)
