我开始使用 @pandas_udf 对于pyspark，在使用文档中的示例进行测试时，我发现了一个无法解决的错误。
我运行的代码是：

from pyspark.sql import SparkSession
from pyspark.sql.functions import pandas_udf, PandasUDFType

spark = SparkSession.builder.getOrCreate()

df = spark.createDataFrame(
    [(1, 1.0), (1, 2.0), (2, 3.0), (2, 5.0), (2, 10.0)],
    ("id", "v"))

@pandas_udf("id long, v double", PandasUDFType.GROUPED_MAP)
def subtract_mean(pdf):
    # pdf is a pandas.DataFrame
    v = pdf.v
    return pdf.assign(v=v - v.mean())

df.groupby("id").apply(subtract_mean).show()

我得到的错误是：

Py4JJavaError: An error occurred while calling o53.showString.
: org.apache.spark.SparkException: Job aborted due to stage failure: Task 44 in stage 7.0 failed 1 times, most recent failure: Lost task 44.0 in stage 7.0 (TID 132, localhost, executor driver): java.lang.IllegalArgumentException: capacity < 0: (-1 < 0)

我正在使用：

pyspark                   2.4.5
py4j                      0.10.7            
pyarrow                   0.15.1
