[Mne_analysis] Using fsaverage subject and a built-in EEG montage

[Gladia Hotan]

        External Email - Use Caution        

Hi,

I get the same error when running mne.viz.plot_alignment:

*line 1765, in trait_set*
*    for name, value in traits.items():*
*ValueError: The truth value of an array with more than one element is
ambiguous. Use a.any() or a.all()*

There seems to be a problem with the 'traits' object handled by mayavi.
Does anyone know how I can troubleshoot this?

Thanks and Best,
Gladia
