error when using create_3d_figure

[cmelot (Clothilde)]

Hello !

when I type in a Python3 console or in Spyder

import mne
fig_roots = mne.viz.create_3d_figure(size=(600, 400), bgcolor=(0, 0, 0))

I get the following error

Using pyvistaqt 3d backend.

Do you see how I could fix this issue ?

Thank you very much
with best regards

Are you by any chance using Wayland? 3D graphics are currently not supported on Wayland (because VTK doesn’t support the EGL context provided by QT… it’s technical and I hope they support it one day). What I do instead is set the environment variable QT_QPA_PLATFORM=xcb before running python (or ipython, or jupyter) to force graphics to run in XWayland compatibility mode. Not perfect but it does work.

Thank you very much for your answer. I tried in a terminal

(fosfornew) melot@93A51:~$ export QT_QPA_PLATFORM=xcb
(fosfornew) melot@93A51:~$ spyder&
[1] 9135
(fosfornew) melot@93A51:~$ Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.

and running my code I got the following error in the Ipython Terminal of Spyder.
The figure did not show up with the commande create_3d_figure but when I run

surfer_kwargs = dict(
surface=“white”, # pial
hemi=“both”,
subjects_dir=subjects_dir,
clim=“auto”,
views=“lat”,
initial_time = 0,
time_unit=“s”,
size=(800, 800),
smoothing_steps=5, )

brain_both = stc_Roots.plot(**surfer_kwargs, figure=fig_roots)
brain_both.add_text(0.1, 0.9,‘visualization of roots by level’, “title”, font_size=16)

A figure showed up but this was impossible to access to the data.

Do you think I can fix the issue ?
Thank you by advance !

with best regards !

I can only get 3d graphics in spyder to work if I start it like this:

QT_QPA_PLATFORM=xcb QT_API=pyqt5 spyder
