[Mne_analysis] mne.viz.plot_source_estimates generates a blank window

[Gladia Hotan]

Hi, I ran mne.viz.plot_source_estimates(stc,subject=<subject_name>,...) but
I got a blank window and this error:

before gtk_init()

TypeError: Argument given by name ('attribList') and position (3)

I get the same error whether or not I set the 'SUBJECT' environment
variable (using os.environ['SUBJECT']=<subject_name>. Could anyone tell me
how to get around this?

Best,
