Sorry, needs a restamp. Found out that pretty file names results in duplicate log files so removed it. |

Discovered a bug recently where DDP worker log files were being created but not written to.
Ultimately discovered that this is caused by spawned subprocesses using python's logging module by default as they create a new interpreter. Adding
logging.use_absl_handler()(suggested by Wei) solves this issue.One mystery that remains is that hobot1 projects didn't seem to have this issue with no recent code changes to
train.pyoffering any hints. Low priority figuring this out for now as this new change fixes the current main.
