rerender to get Python 3.6 and numpy 1.13 builds

[grlee77]

Assuming this works, it should replace PRs #10 and #12.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

I think PyQt may have to be <5 for this to work (IIRC pyface and traitsui master branches work with Qt5, but not their released versions).

The build failure on CircleCI seems unrelated to that, though:

+ DISPLAY=localhost:1.0
+ xvfb-run -a bash -c /feedstock_root/build_artefacts/mayavi_1497296709396/_b_env_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_place/bin/python setup.py install --single-version-externally-managed --record record.txt
  File "<stdin>", line 1
    upload_or_check_non_existence /recipe_root conda-forge --channel=main || exit 1
    ^
IndentationError: unexpected indent

using Xvfb directly rather than relying on xvfb-run has fixed all of the CircleCI build failures. I am not sure what changed that was causing the prior approach not to work.

This may also help when adding OS X builds in the future because OS X seems to come with Xvfb, but not xvfb-run. Currently the lack of VTK packages for OS X is preventing testing that here.

Hi guys, I've been working with Mayavi and python 3.5, and today I did some research regarding python 3.6 support and I found this pull request, which seems to have fixed python 3.6 support. I installed it with no problems, however, when I import mlab I get te following:

    from mayavi import mlab
  File "C:\ProgramData\Anaconda3\lib\site-packages\mayavi\mlab.py", line 27, in <module>
    from mayavi.tools.camera import view, roll, yaw, pitch, move
  File "C:\ProgramData\Anaconda3\lib\site-packages\mayavi\tools\camera.py", line 25, in <module>
    from .engine_manager import get_engine
  File "C:\ProgramData\Anaconda3\lib\site-packages\mayavi\tools\engine_manager.py", line 14, in <module>
    from mayavi.core.engine import Engine
  File "C:\ProgramData\Anaconda3\lib\site-packages\mayavi\core\engine.py", line 27, in <module>
    from tvtk.common import is_old_pipeline
  File "C:\ProgramData\Anaconda3\lib\site-packages\tvtk\common.py", line 13, in <module>
    vtk_major_version = vtk.vtkVersion.GetVTKMajorVersion()
AttributeError: module 'vtk' has no attribute 'vtkVersion'

I would like to help with the Mayavi project, however I'm not any specialist whatsoever, but would be glad if I could help by freeing you some time.

@jorgesmok:
It seems like there is a problem with your VTK package. Can you paste the output of conda info and conda list vtk?
I did not encounter this problem when I tried it just now (I am on 64-bit linux with Python 3.6). (although the fact that mayavi is pinned to older VTK 7.1 rather than the current 8.0 package did cause some other things to be rolled back to earlier versions to satisfy pinning requirements).
