Plotting Dipole orientations with MNE 15.0

Hi

I am trying to compute and plot the orientation of the dipoles and i
have been following the tutorial.

stc_vec = apply_inverse(evoked, inverse_operator, lambda2,
                        method=method, pick_ori='vector')

The above computes fine, and gives me the stc_vec file. I am using
dSPM for method and my snr = 1.
lambda2 = 1. / snr ** 2

The previous source estimate plots on the individual brain and average
brain are all fine.

However, when i plot the stc_vec,

stc_vec.plot(hemi='rh', subjects_dir=subjects_dir,
             clim=dict(kind='value', lims=[8, 12, 15]),
             initial_time=time_max, time_unit='s')

it gives me the following error.
Traceback (most recent call last):

hi Nithya,

you need to update your pysurfer

pip install -U pysurfer

let us know if it does not fix the problem.

ALex

It worked! Thanks!
