The goal was to install the Enthought Mayavi 3D graphics and visualization package, with its newly added Python 3.x support, in an installation of WinPython 3.x. The necessary libraries are over 30 Mb in size, so for now it is advisable to have a means to install this package that is independent of the main WinPython distribution.

OS: Windows 8.1 64-bit Distribution: WinPython 3.5.2.3 64-bit (QT4)

Procedure

Downloaded the appropriate wheels from Christophe Gohlke's site (first installing VTK, traits, traitsui and a few other ETS packages, just to be sure, then finally mayavi 4.5.0 itself). I dragged and dropped the wheels into the WinPython Control Panel. Downloaded and ran a test program from the Mayavi website to make interactive dialogs. The program worked perfectly.

Notes

There was a small error message to the console: "libpng warning: iCCP: known incorrect sRGB profile", but the interactive program seemed to work OK.

OS: Windows 8.1 64-bit, Windows 10 64-bit Distribution: WinPython 3.6.2.0 64-bit (QT5)

Update: I made this work with QT5 and Python 3.6 by:

1. Setting the environment variables ETS_TOOLKIT=qt4 , QT_API=pyside
2. Fetching and installing the latest PySide wheel for Python 3.6 from Gohlke's site

Again, some warning messages to the console but the example Mayavi application GUI (mlab_interactive_dialog.py) worked just fine.
