Package: mayavi2 Version: 4.7.1-2+b2 Severity: important X-Debbugs-Cc: schampail...@skynet.be
Dear Maintainer, Running mayavi2 from the console leads to a crash: stefan@debian:~$ mayavi2 Exception occurred in traits notification handler. Please check the log file for details. Exception occurred in traits notification handler for object: <mayavi.plugins.mayavi_ui_plugin.MayaviUIPlugin object at 0x7f2115a2ff40>, trait: application, old value: None, new value: <mayavi.plugins.mayavi_workbench_application.MayaviWorkbenchApplication object at 0x7f2114d75ae0> Traceback (most recent call last): File "/usr/lib/python3/dist-packages/traits/trait_notifiers.py", line 654, in _dispatch_change_event self.dispatch(handler, *args) File "/usr/lib/python3/dist-packages/traits/trait_notifiers.py", line 553, in dispatch handler(*args) File "/usr/lib/python3/dist-packages/traits/traits_listener.py", line 498, in handle_simple self.next.register(new) File "/usr/lib/python3/dist-packages/traits/traits_listener.py", line 464, in register value = getattr(self, type)(new, name, False) File "/usr/lib/python3/dist-packages/traits/traits_listener.py", line 738, in _register_simple return next.register(getattr(object, name)) File "/usr/lib/python3/dist-packages/envisage/ui/workbench/workbench_application.py", line 140, in _gui_default return GUI(splash_screen=self.splash_screen) File "/usr/lib/python3/dist-packages/mayavi/plugins/mayavi_workbench_application.py", line 118, in _splash_screen_default splash_screen = SplashScreen( File "/usr/lib/python3/dist-packages/pyface/base_toolkit.py", line 178, in __init__ raise NotImplementedError(msg % (toolkit, package, name)) NotImplementedError: the null pyface.ui.null backend doesn't implement splash_screen:SplashScreen I didn't investigate the exact origin of the crash but found a work around. According to : https://github.com/enthought/mayavi/issues/838 doing this before running seems to solve the bug: export ETS_TOOLKIT=qt export QT_API=pyqt5 After those exports, I can run mayavi2 correctly. Maybe one could write a small wrapper around mayavi2 commands that detects the appropriate setup to create to run it ?
