my system is ubuntu 18.04, when installing mne, now python is automatically installed version 3.10.0, however, it will lead the problem that cannot run the programme.
heres the code:

(mne) root@clifford-Alienware-15:~/Documents/dongyang/codes# python split_code_v3.py
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
Traceback (most recent call last):

    from surfer import Brain
  File "/home/clifford/miniconda3/envs/mne/lib/python3.10/site-packages/surfer/__init__.py", line 1, in <module>
    from .viz import Brain, TimeViewer  # noqa

    from collections import Sequence
ImportError: cannot import name 'Sequence' from 'collections' (/home/clifford/miniconda3/envs/mne/lib/python3.10/collections/__init__.py)

pysurfer needs an update for 3.10

mne now recommends you use pyvista as 3D backend

Thanks, but how can I switch?

4

the code I used

from surfer import brain

don’t know how to switch to pyvista

see https://mne.tools/stable/generated/mne.viz.set_3d_backend.html

6

so is it possible to switch

from surfer import brain

to

mne.viz.set_3d_backend(brain, verbose=None)

?

7

mne.viz.set_3d_backend(brain, verbose=None)
from mne.viz import Brain

this should work almost exactly as PySurfer

8

it comes with

name 'verbose' is not defined

however I import pyvista and pyvistaqt and mne

What if you try:

mne.set_3d_backend('pyvistaqt')
from mne.viz import Brain

?

Or even the following should work:

from mne.viz import get_brain_class
Brain = get_brain_class()
