eric-haibin-lin commented on issue #17237: Data imbalance handling in MXNet Gluon URL: https://github.com/apache/incubator-mxnet/issues/17237#issuecomment-571816894 I recently updated the split sampler in gluonnlp, such that the number of samplers for each worker will always be the same (with `even_size=True`). https://gluon-nlp.mxnet.io/master/api/modules/data.html?highlight=splitsampler#gluonnlp.data.SplitSampler This somewhat avoids the imbalanced data batch problem. If it is useful I can upstream the sampler to mxnet, too
