problème avec PywFM

Bonjour tt le monde,

Sous python (jupyter notebook), j'exécute le code suivant :

import pywFM
import numpy as np
import pandas as pd

features = np.matrix([
# Users | Movies | Movie Ratings | Time | Last Movies Rated
# A B C | TI NH SW ST | TI NH SW ST | | TI NH SW ST
[1, 0, 0, 1, 0, 0, 0, 0.3, 0.3, 0.3, 0, 13, 0, 0, 0, 0 ],
[1, 0, 0, 0, 1, 0, 0, 0.3, 0.3, 0.3, 0, 14, 1, 0, 0, 0 ],
[1, 0, 0, 0, 0, 1, 0, 0.3, 0.3, 0.3, 0, 16, 0, 1, 0, 0 ],
[0, 1, 0, 0, 0, 1, 0, 0, 0, 0.5, 0.5, 5, 0, 0, 0, 0 ],
[0, 1, 0, 0, 0, 0, 1, 0, 0, 0.5, 0.5, 8, 0, 0, 1, 0 ],
[0, 0, 1, 1, 0, 0, 0, 0.5, 0, 0.5, 0, 9, 0, 0, 0, 0 ],
[0, 0, 1, 0, 0, 1, 0, 0.5, 0, 0.5, 0, 12, 1, 0, 0, 0 ]
])
target = [5, 3, 1, 4, 5, 1, 5]

fm = pywFM.FM(task='regression', num_iter=5)

# split features and target for train/test
# first 5 are train, last 2 are test
model = fm.run(features[:5], target[:5], features[5:], target[5:])
print(model.predictions)
# you can also get the model weights
print(model.weights)


mais il me donne l'erreur suivant : EmptyDataError: No columns to parse from file

au niveau de la ligne de code model = fm.run(features[:5], target[:5], features[5:], target[5:])

voilà le lien de la source de mon code : https://github.com/jfloff/pywFM#installing

merci d'avance
