[Mne_analysis] plot_read_foward.py and plot_make_forward.py error

[Alexandre Gramfort]

hi Junpeng,

I assume you work on a windows machine. To allow parallel computing
you need to start the functions using "if __name__ == '__main__'".

Your script should look something like this:

if __name__ == '__main__':
    import mne
    mne. ...
