示例1: test_set_pipeline_steps
# 需要导入模块: from sklearn.pipeline import Pipeline [as 别名]
# 或者: from sklearn.pipeline.Pipeline import steps [as 别名]
def test_set_pipeline_steps():
transf1 = Transf()
transf2 = Transf()
pipeline = Pipeline([('mock', transf1)])
assert_true(pipeline.named_steps['mock'] is transf1)
# Directly setting attr
pipeline.steps = [('mock2', transf2)]
assert_true('mock' not in pipeline.named_steps)
assert_true(pipeline.named_steps['mock2'] is transf2)
assert_equal([('mock2', transf2)], pipeline.steps)
# Using set_params
pipeline.set_params(steps=[('mock', transf1)])

# Using set_params to replace single step
pipeline.set_params(mock=transf2)
assert_equal([('mock', transf2)], pipeline.steps)
# With invalid data
