validation score is not improving by at least tol for
``n_iter_no_change`` consecutive epochs. The split is stratified,
except in a multilabel setting.
If early stopping is False, then the training stops when the training
loss does not improve by more than tol for n_iter_no_change consecutive
passes over the training set.
Only effective when solver='sgd' or 'adam'
