我是pyspark的新手，我试图用pyspark在prophet中运行多个时间序列（作为分布式计算，因为我有100个时间序列要预测），但我有如下错误。

import time 
start_time = time.time()
sdf = spark.createDataFrame(data)
print('%0.2f min: Lags' % ((time.time() - start_time) / 60))
sdf.createOrReplaceTempView('Quantity')
spark.sql("select Reseller_City, Business_Unit, count(*) from Quantity group by Reseller_City, Business_Unit order by Reseller_City, Business_Unit").show()
query = 'SELECT Reseller_City, Business_Unit, conditions, black_week, promos, Sales_Date as ds, sum(Rslr_Sales_Quantity) as y FROM Quantity GROUP BY Reseller_City, Business_Unit, conditions, black_week, promos, ds ORDER BY Reseller_City, Business_Unit, ds'
spark.sql(query).show()
sdf.rdd.getNumPartitions()
store_part = (spark.sql(query).repartition(spark.sparkContext.defaultParallelism['Reseller_City','Business_Unit'])).cache()

store_part.explain()

from pyspark.sql.types import *

result_schema =StructType([
  StructField('ds',TimestampType()),
  StructField('Reseller_City',StringType()),
  StructField('Business_Unit',StringType()),
  StructField('y',DoubleType()),
  StructField('yhat',DoubleType()),
  StructField('yhat_upper',DoubleType()),
  StructField('yhat_lower',DoubleType())
  ])
from pyspark.sql.functions import pandas_udf, PandasUDFType

@pandas_udf( result_schema, PandasUDFType.GROUPED_MAP )
def forecast_sales( store_pd ):
    
    model = Prophet(interval_width=0.95, holidays = lock_down)
    model.add_country_holidays(country_name='DE')
    model.add_regressor('conditions')
    model.add_regressor('black_week')
    model.add_regressor('promos')
    
    train = store_pd[store_pd['ds']<'2021-10-01 00:00:00']
    future_pd = store_pd[store_pd['ds']>='2021-10-01 00:00:00']
    model.fit(train[['ds', 'y', 'conditions', 'black_week', 'promos']])

    forecast_pd = model.predict(future_pd[['ds', 'conditions', 'black_week', 'promos']])  

    f_pd = forecast_pd[ ['ds','yhat', 'yhat_upper', 'yhat_lower'] ].set_index('ds')

    #store_pd = store_pd.filter(store_pd['ds']<'2021-10-01 00:00:00')

    st_pd = future_pd[['ds','Reseller_City','Business_Unit','y']].set_index('ds')

    results_pd = f_pd.join( st_pd, how='left' )
    results_pd.reset_index(level=0, inplace=True)

    results_pd[['Reseller_City','Business_Unit']] = future_pd[['Reseller_City','Business_Unit']].iloc[0]

    return results_pd[ ['ds', 'Reseller_City','Business_Unit','y', 'yhat', 'yhat_upper', 'yhat_lower'] ]
results = (store_part.groupBy(['Reseller_City','Business_Unit']).apply(forecast_sales).withColumn('training date', current_date() ))
results.cache()
results.show()

所有的行都执行得很完美，但错误来自**results.show（）**line我不明白我哪里做错了，非常感谢如果有人帮助我

您也可以按照以下步骤设置os env变量，在SparkSession/SparkContext之前运行此操作

import os
import sys

os.environ['PYSPARK_PYTHON'] = sys.executable
os.environ['PYSPARK_DRIVER_PYTHON'] = sys.executable

对我很有效

确保您已经设置spark.conf.set（“spark.sql.execution.arrow.pyspark.enabled”，“true”）
阅读更多内容：https://spark.apache.org/docs/3.0.1/sql-pyspark-pandas-with-arrow.html
如果这不起作用，尝试增加驱动程序和工作程序内存大小。
