Hi @Darinyazanr,
maybe "pickle" library can help you
code as follows:

import pickle

fm = pylibfm.FM()
fm.fit(X,y)

with open('fm_model.pkl', 'wb') as f:
    pickle.dump(fm, f)
del fm # make sure variable is empty 
with open('fm_model.pkl', 'rb') as f:
    fm = pickle.load(f)

fm.predict(v.transform({"user": "1", "item": "10", "age": 24}))

after that
you'll get a file named "fm_model.pkl" under the same directory

@YiJingLin is that really worked? the pyfm.pylibfm.FM does not have a write attribute
