错误导入MulticlassClassificationEvaluator

Question

我学习火花（Pyspark），并试图导入MLLIB库，我遇到这个奇怪的错误来了MulticlassClassificationEvaluator无法导入：

from pyspark.ml import Pipeline 
from pyspark.ml.classification import DecisionTreeClassifier 
from pyspark.ml.feature import StringIndexer, VectorIndexer 
from pyspark.mllib.util import MLUtils 
from pyspark.ml.evaluation import MulticlassClassificationEvaluator 

--------------------------------------------------------------------------- 
ImportError        Traceback (most recent call last) 
<ipython-input-148-0033401bce6e> in <module>() 
4 from pyspark.mllib.util import MLUtils 
----> 5 from pyspark.ml.evaluation import MulticlassClassificationEvaluator 

ImportError: cannot import name MulticlassClassificationEvaluator 

Answer 1

我发现了这个问题。我使用的是spark-1.4.0，显然没有实现MulticlassClassificationEvaluator。
