pylint output (not-callable) when use spatial.cKDTree

Created on 23 Jul 2017 · 2Comments · Source: PyCQA/pylint

Steps to reproduce

conda install scipy (python 3.6)
import scipy.spatial as spatial
spatial.cKDTree
run pylint using configure file for google code style

Current behavior

E: 58,17: spatial.cKDTree is not callable (not-callable)

Expected behavior

spatial.cKDTree run well in my project, I want to know why Pylint gives error.
For me, spatial.cKDTree is callable in ipython, Pylint should not be seeing this as error.

pylint --version output

conda create -y -n pylint_test python=3.6 scipy pylint
using configure file in "https://gist.github.com/rpunkfu/3cd6f8b8b23e27adedbd"
my test python file:

pylint_test_scipy.py

def nearest_ckdtree(self, cities):
    """
    we have m (n, 2) cities and we need to find time series of temperature from
    reanalysis/station obsevations whose coordinates are grids (n, 2)

    Args:
        cities: m cities of (lat, lon in each row)

    Returns:
        lists whose length is same as cities, each element of (indexes, dist) is the index of
        nearest point and the distance between the city and the point.
    """
    import scipy.spatial as spatial

    # points: n points of (lat, lon in each row)
    points = []
    for ix in self.lons:
        for iy in self.lats:
            points.append([iy, ix])
    mytree = spatial.cKDTree(points)
    dist, indexes = mytree.query(cities)

    return dist, indexes"

running pylint --rcfile pylint.conf pylint_test_scipy.py gives

*** Module pylint_test_scipy
E: 20,17: spatial.cKDTree is not callable (not-callable)

Can you provide a short reproducing example? I can't reproduce this bug with the example you gave. Also I tried instantiating the class and Pylint didn't complain at all.
