Trying the code:

epochs.info,
con.get_data(output=‘dense’)[:, :, 0])

Following error is given :
The Mayavi 3D backend is deprecated in 0.24 and will be removed in the next version of MNE-Python. Use the pyvistaqt or notebook backends instead
mne.viz.plot_sensors_connectivity(
qt.qpa.window: <QNSWindow: 0x7f77749487d0; contentView=<QNSView: 0x7f77749483c0; QCocoaWindow(0x600001457180, window=QWidgetWindow(0x600004567a80, name=“QMainWindowClassWindow”))>> has active key-value observers (KVO)! These will stop working now that the window is recreated, and will result in exceptions when the observers are removed. Break in QCocoaWindow::recreateWindowIfNeeded to debug.

Request to please help with this. Thanks.

:question: If you have a question or issue with MNE-Python, please include the following info:

  • MNE version: e.g. 0.24.0
  • operating system: e.g. macOS 12 / Windows 10 / Ubuntu 18.04

:page_facing_up: Please also provide relevant code snippets – ideally a minimal working example (MWE).

:fountain_pen: To get the correct formatting, paste your Python code, then select it, and click on the Preformatted text toolbar button.

:no_mobile_phones: Please avoid sharing screenshots of code and error messages! Screenshots are difficult to work with especially on mobile devices; they don’t allow others to copy code and other text; and they don’t show up in the search.
