我最近使用anaconda将pyspark从2.4.5更新到2.4.6。但是，当我尝试初始化jupyter笔记本（或以另一种方式运行它）时，以下代码会抛出一个错误，而在更新之前没有：

import pyspark
from pyspark.sql import SparkSession
from pyspark.sql.functions import * 
from pyspark.sql.types import *
import pandas as pd
import os, shutil
import numpy as np
import matplotlib.pyplot as pl
os.environ["ARROW_PRE_0_15_IPC_FORMAT"] = "1"

spark = SparkSession.builder \
        .master('local[2]') \
        .appName('chapter2') \
        .config('spark.jars.packages', 'io.delta:delta-core_2.11:0.4.0') \ # <--- here it shows the error
        .config('spark.executor.memory','6gb') \
        .getOrCreate()

sc = spark.sparkContext
spark.sql("set spark.sql.shuffle.partitions = 1")

错误如下：

---------------------------------------------------------------------------

我已经卸载了pyspark、pyarrow、py4j、koalas，并更改为最新版本，但我仍然面临同样的问题。如果有人知道会发生什么，能帮助我，我将不胜感激。
