Reworks network interfaces arguments in two places: the
horovod.run
API and thehorovodrun
CLI:The
horovod.run
API deprecatesnetwork_interface
argument in favour ofnetwork_interfaces
, which becomes a list of strings, rather than a comma separated string that is to be split.The
horovodrun
CLI replaces--network-interface
with semantically more accurate--network-interfaces
, which still takes a comma separated string of network interfaces, but also provides the new--network-interface
argument, that semantically correctly expects a single network interface. That argument can be used multiple times to set multiple NICs.Arguably,
--network-interfaces
could be removed completely, as--network-interface
allows to specify multiple NICs. Unless, there is any use of comma separated strings.
