原因：在linux系统中可以使用多个子进程加载数据，而在windows系统中不能。在windows系统中需要将进程数设置为单进程，所以我们需要将数据处理语句这部分的参数num_workers=2改为num_workers=0即可解决错误。

运行YOLOV8时碰到：RuntimeError: An attempt has been made to start a new process before the current proce

通常发生在使用多进程模块（如Python的 multiprocessing ）时，尤其是在Windows系统上，因为Windows没有Unix-like系统上的 fork 系统调用，而是使用 spawn 来创建新进程。如果是，那么在这个块中启动多进程代码。通过将多进程代码放在 if __name__ == '__main__': 块中，可以确保只有当模块作为主程序运行时，这些代码才会被执行，从而避免无限递归创建子进程。完整报错如上所示，查阅了一番资料还有ai以后。得到问题所在和解决方案。

错误提示表明在Windows环境下，多进程的启动方式（spawn）要求主模块必须被保护在代码块中，否则子进程会重复执行主模块的代码。YOLO的数据加载器默认会使用多进程（通过workers参数控制），而Windows系统的进程创建方式与Linux不同，需要严格遵守的编程规范。
