Installation

pip install pointgrid

Usage

from pointgrid import align_points_to_grid
from sklearn import datasets

# create fake data
arr, labels = datasets.make_blobs(n_samples=1000, centers=5)

# get updated point positions
updated = align_points_to_grid(arr)

updated will be a numpy array with the same shape as the input array arr.
