yuxihu edited a comment on issue #14431: Add post initialization callback for Gluon Parameter URL: https://github.com/apache/incubator-mxnet/pull/14431#issuecomment-473075802 > why not do the synchronization after you know the initialization is complete? adding callback is generally not recommended as it's obscure to use. It can be done like that. Users need to broadcast parameters in the Gluon train loop after the first forward pass. Based on my offline discussion with @eric-haibin-lin, we do not think that's a very good user experience. In addition, with the upcoming Gluon fit API, users may not need to write the train loop anymore. In that case, we still need a way to sync the parameters.
