--- Comment #2 from vialav <d...@bk.ru> --- > mayavi works only with `qt5`, and crash, if I try to use `qt4` or `wx` Qt4: yes, the above happens because your and my tools **are Qt5-compiled** what clashes with Qt4 implementation (either of them, but not both). You need to have a very old-old `jupyter-qtconsole` compiled against Qt4 to have the working Qt4 backend (I couldn't find it in a meaningful time on the Internet; and in any case Mayavi's official way defaulting to Qt4 seems an oudated choice for today; just edit your qt/__init__.py in `pyface` for convenience ;-) …or `pyside`, which is Qt4-based; …or `pyside2`, which is Qt5-based, so it stands a chance, but only with the following two consequtive fixes, see the discussion here: https://stackoverflow.com/q/52337856 https://bugreports.qt.io/browse/PYSIDE-816 https://codereview.qt-project.org/c/pyside/pyside-setup/+/252439 https://bugreports.qt.io/browse/PYSIDE-1003 https://codereview.qt-project.org/c/pyside/pyside-setup/+/261332 …or, indeed, `wx` for Python/Python3: https://packages.ubuntu.com/src:wxpython3.0 https://packages.ubuntu.com/src:wxpython4.0 /wxpython4.1 (available in beta in the wild), I also could not understand why `wx` is not working; may-be some sort of a Python wx-based or agnistic IDE is needed for that for testing (IDLE?). -- You are receiving this mail because: You are watching all bug changes.
