pyspark 出現pyspark.sql.utils.IllegalArgumentException: 'requirement failed: Column prediction must be of type double but was actually float.'異常

在pyspark的交互式環境下調用pysark.ml中的MulticlassClassificationEvaluator執行下列命令做評估時會出現下面那個問題，但在代碼中通過spark-submit提交時則可以正常運行。

from pyspark.ml.evaluation import  MulticlassClassificationEvaluator

evaluatorMC = MulticlassClassificationEvaluator().setLabelCol("score").setPredictionCol("prediction")
Accuracy = evaluator.evaluate(predictions)
