示例1: test_drop_empty_samples
# 需要导入模块: from pml.data.model import DataSet [as 别名]
# 或者: from pml.data.model.DataSet import drop_empty_samples [as 别名]
def test_drop_empty_samples(self):
df = pd.DataFrame([[1, 2, np.NAN], [np.NAN, np.NAN, np.NAN], [7, 8, 9]])
original = DataSet(df, labels=["a", "b", "c"])
filtered = original.drop_empty_samples()
assert_that(filtered.feature_list(), has_length(3))
assert_that(filtered.num_samples(), equal_to(2))
assert_that(filtered, equals_dataset([[1, 2, np.NAN], [7, 8, 9]]))
assert_that(filtered.get_labels(), contains("a", "c"))示例2: test_drop_empty_samples_original_unchanged
