   The optimizer object in kvstore is probably referring the same optimizer object you modified. This could work for single-machine training. See https://github.com/apache/incubator-mxnet/blob/master/python/mxnet/module/module.py#L530-L545
   It definitely doesn't work for multi-machine training. 
   
   I'd suggest you use `lr_scheduler` instead to make sure the modification works for all scenarios.
