我是PySpark的新手，并尝试在本地设置环境。 我安装了Spark，Hadoop，PySpark，Livy和Sparkmagic，但是在Jupyter笔记本中运行PySpark代码失败。当我将内核更改为Spark并运行Scala代码时，它起作用了。不知何故，只有Pyspark和Pyspark3无法正常工作。我得到的错误如下：
The code failed because of a fatal error:
Session 1 unexpectedly reached final status 'error'. See logs:

Some things to try:
a) Make sure Spark has enough available resources for Jupyter to create a Spark context.
b) Contact your Jupyter administrator to make sure the Spark magics library is configured correctly.
c) Restart the kernel.
谢谢。
