Update recipe to Python 3.6

[majahn]

Hi, thanks a lot for your great work in bringing Mayavi to Python 3!!! It's awesome... ;-)

This conda-recipe worked like charm for Python 3.5 on my Mac. Unfortunately, it does not work yet for Python 3.6:

conda install -c menpo mayavi Fetching package metadata ..................... Solving package specifications: ....

UnsatisfiableError: The following specifications were found to be in conflict:

• mayavi
• python 3.6*

I'm a complete newbie to conda builds, so I'm not sure if adding - PYTHON_VERSION: 3.6 to the .travis.yaml file is enough or whether there is more to it... I'm happy to learn to contribute a PR next time ... ;-))

Thanks again.

Ciao, Marcus

Yes, I haven't gone through and made builds for Python 3.6 yet - but in theory it should be as simple as adding 3.6 to the build matrix.

I tired it, but I get the following error:

This might have some useful information: http://www.math.univ-paris13.fr/~cuvelier/mainsu26.html

Looks like we need to build VTK 7.1.1

[mwaskom]

Do you know if VTK 7.1.1 is packaged anywhere for conda? Unfortunately the main anaconda folks seem uninterested in offering mayavi for python 3. It's awesome that this project is supporting it, but I'd really like to be using 3.6!

Any progress guys? Will we be able to work with Python 3.6 in the near future? or should I just downgrade it to 3.5?

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.

I will try it, thank you!
