Mne python coregistration error

External Email - Use Caution

Hello All,
I am facing a problem during the coregistration process to get the
-trans.fif file.
I have reconstructed the anatomical data using freesurfer, used water shed
algo for the bem. But when I am trying to get the -trans.fif file using
mne.gui.coregistration() I am getting the below error :

" mne.gui.coregistration(subject='IR1', subjects_dir=subjects_dir)
    Triangle neighbors and vertex normals...
    Triangle neighbors and vertex normals...

Also when I am trying :
'mne.gui.coregistration(subject='IR1',
subjects_dir=subjects_dir,head_high_res=False) '
I am getting error :
'Triangle neighbors and vertex normals...
    Triangle neighbors and vertex normals...
Segmentation fault (core dumped) '

Please help with the above issue.
Regards,
Abhishek.
