Describe the bug
On arm processors (AWS:gravition2, rhel), I get the following failure in version 0.23.1
1038 >>> from sklearn.model_selection import train_test_split
1039 >>> X, y = make_classification(random_state=0)
1040 >>> X_train, X_test, y_train, y_test = train_test_split(
1041 ... X, y, random_state=0)
1042 >>> clf = GradientBoostingClassifier(random_state=0)
1043 >>> clf.fit(X_train, y_train)
1044 GradientBoostingClassifier(random_state=0)
1045 >>> clf.predict(X_test[:2])
1046 array([1, 0])
1047 >>> clf.score(X_test, y_test)
Expected:
0.88
Got:
0.84
Steps/Code to Reproduce
