在 python 3 中难以使用 mayavi

Question

我在windows上用的是python 3.5，按照mayavi的教程，用的是python 2.7，根据我以前的经验，版本应该不会是一个很大的障碍，但事实证明这是一个很大的障碍。这是一个简单的测试代码：

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)

这就是我得到的（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.

PyQT: http://www.riverbankcomputing.co.uk/software/pyqt/intro

而且我很确定我已经安装了 wxPython、traits 和 PyQt（版本 5），但不确定是否安装了 TraitsBackendWx 或 TraitsBackendQt，我搜索了，但没有找到任何可用的包 python 3... 但是 sence mayavi 有一个 python 3 版本，必须有一种方法可以在 python 3（我想...）上使用运行 mayavi 代码。那么，有什么办法可以解决这个问题吗？

Answer 1

TraitsBackendWx, TraitsBackendQt, Traits, TraitsGUI, Traits backend, wxPython or PyQT 这些包我都不缺，我需要的是 PySide 包...

pip install PySide-1.2.4-cp35-cp35m-win_amd64.whl

包裹（来自第三方，请注意）位于 https://github.com/krrr/PySide/releases/download/1.2.4-1/PySide-1.2.4-cp35-cp35m-win_amd64.whl。

Answer 2

我通过以下方式在 ubuntu 中使用它： sudo apt-get 安装 python3-pyside

其他相关模块是： vtk 8.1.0 玛雅维 4.5.0 python3.5.2
