from mne.report import Report
from mne.datasets import sample
from mne import read_evokeds
from matplotlib import pyplot as plt


data_path = sample.data_path()
meg_path = data_path + '/MEG/sample'
subjects_dir = data_path + '/subjects'
evoked_fname = meg_path + '/sample_audvis-ave.fif'

Do standard folder parsing (this can take a couple of minutes):

report = Report(image_format='png', subjects_dir=subjects_dir,
                info_fname=evoked_fname, subject='sample',
                raw_psd=False)  # use False for speed here
report.parse_folder(meg_path, on_error='ignore', mri_decim=10)
