Description

Currently, DDP creates multiple folders.

  • To fix this, we introduce broadcast_from_master which basically broadcasts a value (here str) from master to all other nodes
  • This change required to move some ddp utils functions from training.utils.distributed_training_utils to common.environment.ddp_utils. This is handled with deprecation, but the deprecation function was introduced in Add deprecate module #1416 which is why it should be merged first
