我在cmd中启动了pyspark并执行了下面的操作来磨练我的技能。

当我执行 a.take(1) 时，出现“_pickle.PicklingError：无法序列化对象：IndexError：元组索引超出范围”错误，但我无法找到原因。当在 google colab 上运行相同的内容时，它不会抛出任何错误。以下是我在控制台中得到的内容。

它应该提供 [1] 作为答案，但却抛出此错误。是因为安装不正确吗？
使用的包 - Spark-3.3.1-bin-hadoop3.tgz、Java(TM) SE 运行时环境（内部版本 1.8.0_351-b10）、Python 3.11.1
任何人都可以帮忙解决这个问题吗？非常感谢。
根据 https://github.com/apache/spark/pull/38987 ，您将需要 Spark 3.4.0 才能使用 Python 3.11，在撰写本文时尚未在 https://spark.apache 上发布。 org/downloads.html。 Python 3.10 应该可以工作。
截至 23 年 3 月 2 日，我遇到了同样的问题，如上所述，我卸载了 python 3.11 并安装了版本 3.10.9，问题已解决！
任何人都可以帮我解决这个问题，因为我将 Pyhton 版本从 3.11 降级到 3.10 python 但仍然存在这个问题
