Can't enable python view in Mayavi2

[Sivapriyasr]

I installed mayavi 4.7.2 , vtk 9, python 3.6, pyqt5. The mayavi aplication is opening but when i enable python view in the others option of the View menu, the mayavi application crashes. And the logger says: WARNING|2021-01-25 16:12:24,255|Can't find the Python shell to bind variables WARNING|2021-01-25 16:12:24,255|'PythonShellView' object has no attribute 'shell'

@yjx12345 can you give us information about your python environment so we can debug what is happening? For example, what version of python are you using, what version of mayavi and vtk are you using, which GUI toolkit are you using (Qt or Wx) and what toolkit wrapper are you using (pyqt5, pyside5, wxpython etc) and what is the version.

You should be able to run python -m pip list or python -m pip freeze and get this information. You can simply copy-paste the output of that command in this discussion.

Hello I would appreciate your help a lot I have a similar issue.. I'm trying to use Mayavi2 in vscode jupyter notebooks and no plots are shown. This error is written instead. I work on Mac my environment has: PyQt5 5.12.3 PyQt5-Qt5 5.15.2 PyQt5-sip 12.11.0 vtk 9.0.3 mayavi 4.8.1.dev0

I think I have an installation problem. Running the app in the terminal gets totally stuck if I test with "nosetests tests" I get

These will stop working now that the window is recreated, and will result in exceptions when the observers are removed.
