import - 无法导入 scipy.spatial.voronoi

Question

我正在尝试使用 scipy 的 Voronoi 镶嵌

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

但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，我从 scipy.spatial 导入其他类没有问题

from scipy.spatial import Delaunay
