我在windows上使用python 3.5，并根据以前的经验，使用python 2.7的mayavi教程后，版本不应该是一个巨大的障碍，但事实证明这是一个巨大的障碍。这里有一个简单的测试代码：难度在python中使用mayavi 3
import numpy as np
from mayavi import mlab
t = np.linspace(0, 4 * np.pi, 50)
x = np.sin(2 * t)
y = np.cos(t)
z = np.cos(2 * t)
s = 1 + np.sin(t)
mlab.points3d(x, y, z, s)
这就是我得到了（我的文件夹名称被删除）

Make sure that you have either the TraitsBackendWx or the TraitsBackendQt
projects installed. If you installed Mayavi with easy_install, try
easy_install <pkg_name>. easy_install Mayavi[app] will also work.
If you performed a source checkout, be sure to run 'python setup.py install'
in Traits, TraitsGUI, and the Traits backend of your choice.
Also make sure that either wxPython or PyQT is installed.
wxPython: http://www.wxpython.org/
PyQT: http://www.riverbankcomputing.co.uk/software/pyqt/intro
而且我敢肯定，我已经安装了wxPython中，性状和PyQt的（第5版） ，但不知道是否安装了TraitsBackendWx或TraitsBackendQt，我搜索了，并没有找到任何可用于python 3的包...但sence mayavi有一个python 3版本，必须有一种方法来运行python上的mayavi代码3（我想......）。那么，有什么办法解决这个问题？
你是自由接受你自己的答案，如果它解决了你。 – Iceman
