无法导入scipy.spatial.voronoi

Question

我正在尝试使用来自scipy的Voronoi曲面细分

http://docs.scipy.org/doc/scipy-dev/reference/generated/scipy.spatial.Voronoi.html

但是python不会导入它

from scipy.spatial import Voronoi
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name Voronoi

但是，我没有从scipy.spatial

导入其他类的问题

from scipy.spatial import Delaunay
