From README:

# create a SleepData object 
from sleepscorer import Scorer, SleepData
file = SleepData('sample-psg.edf', start = 2880000, stop = 5400000, 
                              channels={'EEG':'EEG Fpz-Cz', 'EMG':'EMG submental', 
                                        'EOG':'EOG horizontal'}, preload=False)
# Create and run Scorer
scorer = Scorer([file], hypnograms=True, demo=True)
scorer.run()
# this will only work if you have matplotlib set-up
tools.show_sample_hypnogram('sample-psg.groundtruth.csv', start=960, stop=1800)

Still rolling, I should fix that.

your matplotlib version is too new.

try pip install matplotlib==2.2.5, which was the one used when the project was developed.

Yes, I downgraded the version, now it works. Thanks.
