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

Question

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.

Answer 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
