Review comment:
looking at horovod and byteps, it doesn't seem like it is as easy as passing
kv= argument into gluon.Trainer to use horovod and byteps. Using horovod and
byteps require some code changes as well. So I'm not sure if it is possible to
run launch.py with --horovod/--byteps flag and make them use corresponding
communication mechanisms. It would work for kvstore and p3.
