Error in importing mlab

[adehgha]

After installing all the requirements, I cloned the repo and ran the install script. It went through the installation. I can import the mayavi package in python but I can not import the mlab from within the mayavi package. It complains about not finding the pyface.tvtk_scence.

from mayavi import mlab
Traceback (most recent call last):

Can you provide your setuptools version please? I suspect PR #444 would fix this issue.

$ easy_install --version
setuptools 28.2.0 from /usr/local/lib/python2.7/dist-packages (Python 2.7)

@adehgha -- I've merged #444, can you update your cloned repository and try again and let us know if this works for you please? Thanks!

@prabhuramachandran: The merge actually resolved the error. So now I can import the mlab successfully. However mayavi still doesn't work and terminates with a segmentation fault. I think you can close this issue and I will open up another issue to resolve the segmentation fault.

I have the same problem with anaconda mayavi2 installed with conda install -c menpo mayavi

In [1]: from mayavi import mlab
Segmentation fault (core dumped)

ETS_TOOLKIT=null fixed the import issue for me as mentioned in #439

another comment: anaconda mayavi should have as dependency e.g. this:

conda install qt=4.8.7
conda install pyqt=4.11.4

QT v5 fails and is installed by default by anaconda, also fixed in: #448
