Hugging Face's TRL training library is firefighting two separate CI failures overnight, forcing temporary pins on bitsandbytes and xfailing critical tests against a broken transformers dev build.

The NemotronH parametrization of both GRPO and RLOO trainers started failing when CI installs the dev dependency stack with kernels [1], marking those tests as expected failures (xfail, strict=True) until the upstream transformers issue resolves [3]. In parallel, a bitsandbytes 0.50.0 incompatibility surfaced in the quantization and dev dependency groups, forcing a temporary pin to versions below 0.50.0 across both dependency sets [2] [4]. These aren't production breaks yet, but they're blocking CI validation for anyone running against the dev branch. Over in pytorch-image-models, Ross Wightman merged a model factory path handler fix that also corrects filename and extension priority bugs [5] [6], addressing issue #2725. The repo also cleaned up snapshot download logic and GitHub CI OIDC configuration [7]. All three TRL fixes came from albertvillanova's rapid response to cascading upstream issues.

Action items

→ Monitor transformers dev branch for kernel compatibility fix, then remove TRL xfail markers huggingface/trl [plan]
→ Track bitsandbytes release cycle and prepare to remove version pin once 0.50.0+ is stable huggingface/trl [monitor]
→ Test TRL against latest pytorch-image-models factory path changes if you load models from disk huggingface/pytorch-image-models [plan]
