the instructions are probably obsolete now (works on ubuntu 14.04, not sure
about newer distros). Cf. https://github.com/sfepy/sfepy/issues/379
, see below
for further information.

You do not need to use the wx backend, just remove that line from the config.
The reason it was there was to allow non-blocking mayavi windows. The
configuration to achieve that might differ on new distros.

Try removing the
'import matplotlib as mpl',
Also note, that you can just run ipython with the default profile, and do the
imports from exec_lines manually in order to try the tutorial. Then check the
examples with "interactive" in their names - those show how to import things
properly in a script.
Does that help?
