RuntimeError: DataLoader worker (pid(s) 15912) exited unexpectedly

根据引用中提供的方法，解决RuntimeError: DataLoader worker (pid(s) 15912) exited unexpectedly的方法是进行以下操作：

1. 根据引用的提示，找到相关代码的位置，并将函数体里的代码修改为黄线的语句：

def get_dataloader_workers():
    """Use 4 processes to read the data. Defined in :numref:`sec_fashion_mnist`"""
    return 0 if sys.platform.startswith('win') else 4

2. 可以尝试增加num_workers的值，根据引用的建议，适当增加num_workers可以提高DataLoader的并行性，从而减少DataLoader进程crash的可能性。但是要注意不要增加过多，以免过多占用系统资源。

这些操作可能会帮助解决RuntimeError: DataLoader worker (pid(s) 15912) exited unexpectedly的问题。希望能够帮到你。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
