The environment variable `PYTHONBUFFERED` is not recognized by Python. The correct variable name is `PYTHONUNBUFFERED`, which disables output buffering for stdout/stderr. Additionally, the canonical value for enabling unbuffered mode is `1`, not `16`. Without this fix, Python output buffering remains at its default, which can cause delayed or missing log output — particularly problematic when debugging long-running RL training jobs.

Summary
PYTHONBUFFERED→PYTHONUNBUFFEREDin both launch scripts16to1(the canonical value for enabling unbuffered mode)PYTHONBUFFEREDis not a recognized Python environment variable — Python silently ignores it. The correct variable isPYTHONUNBUFFERED, which disables stdout/stderr buffering when set to any non-empty string.Without this fix, Python output remains fully buffered when piped (e.g., via
ray job submit), causing delayed or lost log output during long-running RL training jobs.Files changed
