Can you share the output of mne.sys_info(): mne.sys_info — MNE 1.7.0.dev151+g14ff9483c documentation

I suspect you are lacking a Qt binding, one of PyQt5, PyQt6, PySide2, Pyside6

These packages were not downloaded in my environment. Yet I used “pip install x” for each of them and same error persists

Only one should be installed. Could you please share the output of sys_info?

I hope this is what you mean

No I mean the output of this MNE function: mne.sys_info — MNE 1.7.0.dev151+g14ff9483c documentation

Which details your environment and the versions of all MNE dependencies.

Thanks for the info

<function mne.utils.config.sys_info(fid=None, show_paths=False, *, dependencies=‘user’, unicode=True, check_version=True)>

I assume there is a problem with path, right?

edit = okay, after checking “pip show mne” in conda. It worked then i thought may be i shall delete existing notebook and created a new one. Here is new mne.sys_info() output

Let’s start with that, as the sys_info reports under visualization dependencies:

unavailable vtk, pyqtgraph, mne-qt-browser, trame_vtk, trame_vuetify

Please install at least vtk and trame_vtk.

In case you are not aware, MNE provides an installer which install an entire conda environment will all its dependencies and more: MNE-Python installers — MNE 1.6.1 documentation
The created environment includes IDEs like Spyder and Jupyter for development. This installer goal is to simplifying the installation process for users and at avoiding this kind of issues with incomplete environment during manual installs.

Also it appears to be trying to use the notebook backend rather than the Qt one. You can use this to set which to use:

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

Depending on your graphics capabilities you might also need something like:

mne.viz.set_3d_options(
    antialias=False, depth_peeling=False, smooth_shading=False, multi_samples=1,
)
