itkwidgets error in Jupyter Notebook #1292

Open minkyu-p opened 4 months ago

minkyu-p commented 4 months ago

I'm trying to set up Jupyter Lab (4.0.11) environment for mayavi 4.8.1 on a remote server.

First of all, I note that 

%env QT_QPA_PLATFORM=offscreen

should be set before importing mlab. Otherwise importing mlab crashes. Then

from mayavi import mlab
mlab.init_notebook('itk')

runs fine. However 

s = mlab.test_plot3d()
s

gives the following error messages depending on the installation method:

  1. conda install -c conda-forge itkwidgets which installs itkwidgets=0.32.6

There is already report on the same problem https://github.com/enthought/mayavi/issues/1202#issue-1531272998 without any solution. 
And I encountered the same error even in my laptop (MacBook Pro).

How do I obtain desired behavior of mayavi with itkwidgets?

Thanks in advance.
