FloatSet object is sensitive to numpy version

[geosciz]

A recent update of numpy package to version 1.13.0 changes the behavior of generators.py. See an example as follows.

import numpy as np
from floater.generators import FloatSet

lon = np.arange(0, 9, dtype=np.float32)
lat = np.arange(-4, 5, dtype=np.float32)
land_mask = np.full(81, True, dtype=bool)
land_mask.shape = (len(lat), len(lon))
land_mask[:,0:2] = False
land_mask
array([[False, False,  True,  True,  True,  True,  True,  True,  True],
       [False, False,  True,  True,  True,  True,  True,  True,  True],
       [False, False,  True,  True,  True,  True,  True,  True,  True],
       [False, False,  True,  True,  True,  True,  True,  True,  True],
       [False, False,  True,  True,  True,  True,  True,  True,  True],
       [False, False,  True,  True,  True,  True,  True,  True,  True],
       [False, False,  True,  True,  True,  True,  True,  True,  True],
       [False, False,  True,  True,  True,  True,  True,  True,  True],
       [False, False,  True,  True,  True,  True,  True,  True,  True]], dtype=bool)
model_grid = {'lon': lon, 'lat': lat, 'land_mask': land_mask}
fs = FloatSet(xlim=(0, 9), ylim=(-4, 5), model_grid=model_grid)
fs.get_rectmesh()

Huh, do you think it is related to the cKDTree? Do dist and neighbor_indices agree between versions?

[rabernat]

@geosciz can you tell us the scipy version on each environment?

[geosciz]

@rabernat 0.19.0 for both.
