Cannot install mayavi for python 2.7

[Master-Matt]

Below is the output of pip install mayavi output.txt

I have tried pip3 and it works fine, but the code I want to use it in is written in 2.7, so I need this version.

The crucial bits I see are: [NerdBox:23388] Signal: Segmentation fault (11) [NerdBox:23388] Signal code: Address not mapped (1) [NerdBox:23388] Failing at address: 0x58fb4b8 also " " " " [NerdBox:23350] Failing at address: 0x4be2bf8 but I don't know what to do about it.

Yes this is a bit of a pain! Can you try this:

export ETS_TOOLKIT=null
pip install mayavi

I am hoping that this works and that pip honors env vars. Otherwise, I can see if this could be done in the setup.py itself but this would mean you will have to clone the repo and try.

Well, that go past wheel and installed, but I'm getting an error when I try to run a test file.

My pyqt is 4.11.4+dfsg-1build4 and traitsui is 6.0.0

@Master-Matt Same issue. Have you found a solution perhaps? Thanks.

@langelesl I found the solution here: https://github.com/charlesq34/frustum-pointnets/issues/65 The palette() TypeError disappeared after installing PySide
