示例1: test_set_feature_union_steps
# 需要导入模块: from sklearn.pipeline import FeatureUnion [as 别名]
# 或者: from sklearn.pipeline.FeatureUnion import transformer_list [as 别名]
def test_set_feature_union_steps():
mult2 = Mult(2)
mult2.get_feature_names = lambda: ['x2']
mult3 = Mult(3)
mult3.get_feature_names = lambda: ['x3']
mult5 = Mult(5)
mult5.get_feature_names = lambda: ['x5']
ft = FeatureUnion([('m2', mult2), ('m3', mult3)])
assert_array_equal([[2, 3]], ft.transform(np.asarray([[1]])))
assert_equal(['m2__x2', 'm3__x3'], ft.get_feature_names())
# Directly setting attr
ft.transformer_list = [('m5', mult5)]
assert_array_equal([[5]], ft.transform(np.asarray([[1]])))
assert_equal(['m5__x5'], ft.get_feature_names())
# Using set_params
ft.set_params(transformer_list=[('mock', mult3)])
assert_array_equal([[3]], ft.transform(np.asarray([[1]])))
assert_equal(['mock__x3'], ft.get_feature_names())
# Using set_params to replace single step
ft.set_params(mock=mult5)
assert_array_equal([[5]], ft.transform(np.asarray([[1]])))
assert_equal(['mock__x5'], ft.get_feature_names())
