may you update code to remove this: cross_validation.py:41: DeprecationWarning

[Sandy4321]

in near future your code may be not running since : cross_validation.py:41: DeprecationWarning

it is output of your test case

from pyfm import pylibfm
from sklearn.feature_extraction import DictVectorizer
import numpy as np
train = [
{"user": "1", "item": "5", "age": 19},
{"user": "2", "item": "43", "age": 33},
{"user": "3", "item": "20", "age": 55},
{"user": "4", "item": "10", "age": 20},
]
v = DictVectorizer()
X = v.fit_transform(train)
print(X.toarray())

so
this warning is for line
from pyfm import pylibfm

it is
