ImportError: cannot import name cross_validation

Question

I cannot import the cross_validation from sklearn library; I use sklearn version 0.20.0

from sklearn import cross_validation

later in the c

Answer 1

cross_validation used to exist as a Scikit package*, but was deprecated at some point.

If you're looking for train_test_split as your code indicates, it's in model_selection:

from sklearn import model_selection

features_train, features_test, labels_train, labels_test = model_selection.train_test_split(
    word_data, authors, test_size=0.1, random_state=42)

_{*Looks like this changed in 0.18.}
