本文详细解析了在尝试启动新进程前当前进程未完成导致的错误，并提供了两种解决方案：一是在main函数中运行多进程；二是将num_workers设置为0，采用单进程加载方式。

报错信息：

An attempt has been made to start a new process before the current process has finished its

原因：多进程需要在main函数中运行，

解决方法1：

加main函数，在main中调用

解决方法2：

num_workers改为0，单进程加载

确定要放弃本次机会？

在按照官方demo做cifar识别的时候，在pycharm上会出现一长串的红色字母，转去jupyter 发现并没有错，就很好奇。对于图像识别分类的时候，在dataloader的时候有时会有num_workers的参数，这表示线程数，num_workers=0表示单线程，num_workers = 2则表示多线程。当是多线程的时候直接运行程序也许会出现这种错误。 RuntimeError: An attempt has been made to start a new process .

在Windows平台进行深度学习训练时，常出现多进程数据加载和主模块保护问题，主要由于Python在Windows和Linux创建多进程逻辑不同。当num_workers>0时，会出现RuntimeError，原因是未正确处理多进程数据加载。解决方案包括：1) 在train.py主模块添加if __name__ == '__main__':保护；2) 临时禁用多进程，将num_workers设为0。此外，如遇GPU内存不足，可降低batch_size。

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改为。①这是因为在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。②这个错误是由于在 Windows 平台上，使用多进程时需要在代码中添加。2、我的代码是第二种情况，要解决这个问题，你可以将你的代码包装在。条件判断，以确保主模块在启动子进程之前已经完成了初始化阶段。条件判断下，就可解决。1、如果代码中有使用了。

方法等待新进程完成。最后，我们输出"新进程已完成"。请注意，这只是一个简单的示例代码，你需要根据你实际使用的编程语言和相关库进行修改和扩展。确保在程序中正确处理和调度进程，以确保顺序和正确的进程间通信。在这个示例中，我们创建了一个主进程，然后在主进程中启动一个新的子进程。在主进程中，我们输出"主进程已启动"，然后创建一个新的。所以示例代码的内容将取决于你具体使用的编程语言和相关库。对象，并指定要执行的函数为。方法启动新进程，并使用。
