when I learn mne through the tutorials, I met problem with section ‘working with sensor locations / visualizing sensors in 3D surface renderings’.
when I tried the code:

fig = mne.viz.plot_alignment(
sample_raw.info, dig=False, eeg=False,
surfaces=, meg=[‘helmet’, ‘sensors’],
coord_frame=‘meg’
)
mne.viz.set_3d_view(fig, azimuth=50, elevation=90, distance=0.5)

I get an error:
Traceback (most recent call last):

Hello @longshejuhua and welcome to the forum!

Could you please share the output of

are we sure that qdarkstyle is installed on your computer?

Alex

I think this indicates that the package is installed, no?

8

can you try in your python terminal to do:

import qdarkstyle

qdarkstyle
print(dir(qdarkstyle))

and paste here what you see

my output is the following :

I see ‘light’ in the list.

can you try:

print(qdarkstyle.light)
getattr(qdarkstyle, “light”)
