导入MulticlassClassificationEvalu时出错

Question

我正在学习Spark（Pyspark），在尝试导入MLLIB库时，我遇到了一个奇怪的错误：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

我发现了问题。我使用的是spark-1.4.0，它显然没有实现multiclassificationevaluator。在
