我尝试运行一个非常简单的Dask程序,如下所示:

我有一个简单的函数,我打算使用Python多处理模块并行运行。但是,我得到了以下错误RuntimeError: An attempt has been made to start a new process before the current process has finished its bootstrapping phase.,该错误建议我添加以下内容:

大多数的网上帖子都是这样建议的,所以。
我添加了它,它起作用了,但我似乎不明白为什么这么简单的一段代码需要它。

我按照指南来尝试,看看是否可以运行一个简单的多处理脚本。在其他问题中已经讨论过,需要来使用多处理来实现我想要实现的目标。
为了遵循初学者指南,我编写了两个函数。
