eric-haibin-lin commented on issue #17651: Distributed training with kvstore crashes if worker has different number of data batches URL: https://github.com/apache/incubator-mxnet/issues/17651#issuecomment-591829871 @hkvision what data iterator/dataloader are you using? if you use data iterator, you can use io.ResizeIter to make sure the size is balanced. For dataloader, you can use the SplitSampler with even_size=True: https://gluon-nlp.mxnet.io/_modules/gluonnlp/data/sampler.html#SplitSampler
