   > * Initializing `trainer = gluon.Trainer(update_on_kvstore=True)` doesn't work. Inspecting `trainer._update_on_kvstore` shows that the value is still set to `False`.
   
   This is fixed.
   
   > * When distributed kvstore is used, by default `gluon.Trainer` doesn't work with `mx.optimizer.LRScheduler` if a worker has more than 1 GPU. To be more specific, the trainer updates once per GPU, the `LRScheduler` object is shared across GPUs and get a wrong update count.
   
   This needs to be fixed.
