torch.distributed.elastic.multiprocessing.api:failed

torch.distributed.elastic.multiprocessing.api:failed报错是出现在使用分布式训练时的一个错误。这个错误的具体原因是在分布式训练过程中，同时使用了sampler和参数shuffle设置为True的dataloader，而这两者是相冲突的。在分布式训练中，sampler已经自动打乱了数据，所以dataloader无需再次打乱数据。因此，解决这个错误的方法是在dataloader时将参数shuffle设置为False即可。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
