[Mne_analysis] mayavi visualization problem

        External Email - Use Caution        

What is your `mne.sys_info()`? You should see that you have `PyQt5 5.13` or
so. If you don't, are you sure you did this step from the macOS installation
instructions
<https://mne.tools/dev/install/mne_python.html#installing-mne-python-and-its-dependencies>
:

pip install "PyQt5>=5.10,<5.14"
