No module names 'wx' #4

On my laptop (archlinux), running mayavi2:

________________________________________________________________________________
Could not load envisage. You might have a missing dependency.
Do you have the EnvisageCore and EnvisagePlugins installed?

If you installed Mayavi with easy_install, try 'easy_install <pkg_name>'.
'easy_install Mayavi[app]' will also work.

If you performed a source checkout and installed via 'python setup.py develop',
be sure to run the same command in the EnvisageCore and EnvisagePlugins folders.

If these packages appear to be installed, check that your numpy and
configobj are installed and working. If you need numpy, 'easy_install numpy'
will install numpy. Similarly, 'easy_install configobj' will install
configobj.
Cadair commented 7 years ago

rather than worrying about building wx is it not possible to make ETS use pyqt? (which I think there are already conda packages for)

dfroger commented 7 years ago

yes, there a doc on toolkit selection ('qt4', 'wx').

On another machine (debian 8), the conda package works for me

Cadair commented 7 years ago

I have not had a chance to try this yet as I am travelling. I also run arch so will do some experiments next time I get a stable internet connection.

dfroger commented 7 years ago

ok, I'm curious to see if the ImportError reproduces for you!

pyqt is already a run requirement.

I don't have my archlinux laptop, so I'll experiment later too...

dfroger commented 7 years ago

I'll have to check for a possible forgotten ETS_TOOLKIT='wx' environment variable on my laptop...

Cadair commented 7 years ago

So by default I get:

 ❯ mayavi2
Traceback (most recent call last):
  File "/opt/miniconda/envs/mayavi/bin/mayavi2", line 6, in <module>
    sys.exit(mayavi.scripts.mayavi2.main())
  File "/opt/miniconda/envs/mayavi/lib/python3.5/site-packages/mayavi/scripts/mayavi2.py", line 647, in main
    '''
ImportError: Could not import backend for traits

and if I set ETS_TOOLKIT='pyqt' I get:

 ❯ mayavi2

dfroger commented 7 years ago

ETS_TOOLKIT was set to wx on my archlinux linux. Unsetting it, mayavi2 works.

@Cadair and does the pyqt package itself works for you?

conda create -c conda-forge -n pyqt pyqt python=3.5
python -c 'from PyQt4.Qt import QKeySequence, QTextCursor'

I have these environement variables

$ env | grep ETS
# nothing

$ env | grep QT
QT_QPA_PLATFORMTHEME=lxqt  # don't know where they come from
QT_PLATFORM_PLUGIN=lxqt
