Python錯誤「類型錯誤：排序（）至多2個參數（3給出）」

我收到「TypeError：排序（）至多2參數（3給出）」運行以下腳本從this tutorial：Python錯誤「類型錯誤：排序（）至多2個參數（3給出）」

import numpy as np 
from mayavi import mlab 

x, y, z = np.ogrid[-10:10:20j, -10:10:20j, -10:10:20j] 
s = np.sin(x*y*z)/(x*y*z) 
sf = mlab.pipeline.scalar_field(s) 
mlab.pipeline.volume(sf)

我使用的python，numpy和mayavi版本分別是3.5.2（Anaconda 4.1.1），1.11.1和4.5.0。 Mayavi安裝使用命令：

conda install --channel https://conda.anaconda.org/menpo mayavi

我已經嘗試了一些其他API的mayavi，他們工作正常。有沒有人有什麼想法可能是錯的？完整的回溯如下。
