How can I install mayavi on Windows for python 3 via conda?

问题

I have a python 3 virtual environment managed by conda on Windows. I want to install the mayavi package via

conda install mayavi

but it says it requires python 2.7.

回答1:

Have your luck with a mayavi package available on other channels, by searching on the Anaconda website.

As of today, the one maintained on the conda-forge channel is compatible with python 3.5 and 3.6. To install it,

conda install -c conda-forge mayavi

If mayavi fails with an

ImportError: Could not import backend for traits

it may be because qt is not installed or that qt5 is installed -- in that case it needs to be downgraded

conda install pyqt=4

Here is something you can try:

If you have Visual Studio installed, and Python Native Development Tools installed.

In Anaconda3, you can get VTK7.1.x from clinicalgraphics

conda install -c clinicalgraphics vtk

Open up the VS20xx x64 Native Command Prompt, setting up PATH for python properly: e.g.

C:\Anaconda3\Scripts\activate.bat C:\Anaconda3

Then install mayavi using pip from source.

pip install mayavi

It compiles successfully with VS2017 and Python 3.6 in windows 10.
