error when trying to use pyvista to plot stc

I am trying to use the new pyvista-plotting for stc (through spyder), on my own data, and this mne-example

When I do not specify a backend, it uses majavi. I tried: mne.viz.set_3d_backend('pyvista')

Output of stc.plot:

File “/home/sh254795/anaconda3/lib/python3.7/site-packages/mne/viz/_brain/_brain.py”, line 201, in init shape=(n_row, n_col), fig=figure)

I’ll work on a patch right now 👍 . But basically, the plotter has a simple routine to detect a notebook environment and it seems that it didn’t work properly in your case. The plotter should behave properly in a regular ipython console for some reason it’s not the case in Spyder, thanks for reporting.

Ok thanks! No more error, but the plot appears in the spyder console and I cannot get it out, i.e. use interactive mode. All the usual setting preferences for ipython console graphics or %matplotlib qt does not help. Any ideas?
