示例1: test_filter_by_feature_value_with_labels
# 需要导入模块: from pml.data.model import DataSet [as 别名]
# 或者: from pml.data.model.DataSet import value_filter [as 别名]
def test_filter_by_feature_value_with_labels(self):
features = ["name", "hair colour"]
df = pd.DataFrame([["Bill", "brown"], ["Bob", "black"],
["Jim", "brown"]], columns=features)
dataset = DataSet(df, labels=["SENG", "SENG", "CENG"])
filtered = dataset.value_filter("hair colour", "brown")
assert_that(filtered.get_labels(),
equals_series({0: "SENG", 2: "CENG"}))示例2: test_filter_by_feature_value
# 需要导入模块: from pml.data.model import DataSet [as 别名]
# 或者: from pml.data.model.DataSet import value_filter [as 别名]
def test_filter_by_feature_value(self):
