[Python-apps-team] Bug#934264: Please update (4.6.2?) and provide/switch to python3

[Yaroslav Halchenko]

Package: mayavi2
Version: 4.5.0-1
Severity: normal

4.5.0 still causes segfaults for me (while trying to build/test python-mne
package).  I could not get to upstream's download page for mayavi2 (server bogs
out), but conda seems to have 4.6.2 https://anaconda.org/anaconda/mayavi  so I guess
it is out there.

Also a new version of python-mne (0.18.x) already dropped python2 support, so
we need mayavi being available in python3. ATM mayavi2 seems to provide only
python2. Given that python2 is going away you might as well just switch to
provide python3 bindings only (but ideally both if only for a bit longer to
smoothen transition)

Cheers and thanks in advance
