Answer 1

The cross-validation functionality has been moved to model_selection. To access it's functionality you may try:

from sklearn.model_selection import cross_validate                                          
from sklearn.model_selection import cross_val_predict                          
from sklearn.model_selection import cross_val_score 
from sklearn.model_selection import train_test_split

See docs and examples at Cross-validation
