Nearest neighbors doesn't work

[devinity1337]

from apricot import FacilityLocationSelection
import numpy

X = numpy.random.uniform(0, 1, size=(500, 500))


FacilityLocationSelection(100,n_neighbors=10, verbose=True).fit(X)

n_neighbors parameter gives an error, when I remove it it works fine.

Can you include the exact error you received? Thanks.

I have a similar error when I import apricot.

What version of apricot and sklearn are you using?

This error can be fixed by replacing the following line in "utils.py" "# from sklearn.neighbors import KNeighborsTransformer" by "from sklearn.neighbors import KNeighborsClassifier as KNeighborsTransformer"
