dbsxdbsx edited a comment on issue #9026: why is it so slow (MXNET0.12)even with NVIDIA V100 GPU? URL: https://github.com/apache/incubator-mxnet/issues/9026#issuecomment-403209937 @ThomasDelteil ,thanks for your answer. I think the problem here is that the dataset of captcha is generated online while training. Therefore, the gpu has to wait until cpu generates new batches of data. I guess this is the main issue, and I guess this is what you mean, right? And another problem is that I didn't see any example about using gluon Dataloader with data produced online---Could you show one? I DO WANT TO make everything with Dataloader.
