Jupyter Notebook中的PySpark问题

如何解决Jupyter Notebook中的PySpark问题

初始化时出现此错误。我已经设置了master和worker，然后启动了它。尽管在设置了master和spark之后，我没有启动spark-shell来直接运行它。有人可以帮忙吗..

代码：

import findspark
import os
os.environ["SPARK_HOME"]="C:\Spark"
findspark.init()
from pyspark.sql import SparkSession
from pyspark import SparkConf,SparkContext

错误：

IndexError                                Traceback (most recent call last)
c:\users\khan\appdata\local\programs\python\python37\lib\site-packages\findspark.py in init(spark_home,python_path,edit_rc,edit_profile)
    142     try:
--> 143         py4j = glob(os.path.join(spark_python,"lib","py4j-*.zip"))[0]
    144     except IndexError:

IndexError: list index out of range

During handling of the above exception,another exception occurred:
