When running under a distributedstrategy, Lightning handles the distributed sampler for you by default. 当在分布式策略下运行时,Lightning默认为你处理分布式采样器。 也就是说,当在默认情况下,如果你使用的是DDP strategy,那么pyTorch Lightning会默认给你的数据集类包装一个DistributedSampler。 在官方文档中有具体...
从这部分代码可以看出,这个dataset比较推荐使用RandomSampler作为video sampler。因为用其它的sampler非常不方便,比如我之前样本不平衡想要WeightedRandomSampler,但是不能传weights进去,只能改写源码。 对于这部分代码我比较疑惑的是,以前用DDP,使用的sampler都是DistributedSampler,需要在每一个epoch调用sampler的set_epoch。这样...
