Restrict Python to <3.14 to prevent CPU RAM OOM in distributed training

Hananeh Oliaei · claude · Hananeh Oliaei · commit 90880bb5e21a · 2026-05-21T16:04:52.000-04:00
Python 3.14.0 caused progressive CPU RAM exhaustion during DDP training.
Downgrading to Python 3.13 resolved the issue. Pin .python-version to
3.13 and update uv.lock accordingly.
