liyujiel opened a new issue #11430: lstm_bucketing example has evenly divide problem with self create dataset
URL: https://github.com/apache/incubator-mxnet/issues/11430
## Description
problem happened with a self-created dataset for lstm_bucketing example
But dataset with rnn-time-major works good
