Python pandas_udf火花错误

我开始在当地玩火花并发现这个奇怪的问题

1) pip install pyspark==2.3.1
    2) pyspark>

    import pandas as pd
    from pyspark.sql.functions import pandas_udf, PandasUDFType, udf
    df = pd.DataFrame({'x': [1,2,3], 'y':[1.0,2.0,3.0]})
    sp_df = spark.createDataFrame(df)

    @pandas_udf('long', PandasUDFType.SCALAR)
    def pandas_plus_one(v):
        return v + 1

    sp_df.withColumn('v2', pandas_plus_one(sp_df.x)).show()

从这里举个例子https://databricks.com/blog/2017/10/30/introducing-vectorized-udfs-for-pyspark.html

知道为什么我一直收到这个错误吗？
