Training Hub v0.9.2
Compatibility release for RHOAI 3.5 GA (AIPCC index).
Dependency Compatibility
- AIPCC 3.5 GA dependency compatibility (#117) — Updated pyproject.toml constraints for AIPCC 3.5 GA package availability: raised openpipe-art cap to allow 0.5.18, removed the transformers<=5.3.0 cap from [grpo], and moved verl to a separate [grpo-verl] extra (not on AIPCC index). Also fixed trl 1.x compatibility by renaming the deprecated
tokenizerparameter toprocessing_classin the LoRA SFT trainer, and movedmax_seq_lengthtoSFTConfig.max_lengthto match the trl 1.x API.
Bug Fixes
- ART 0.5.18 megatron import stub (#118) — openpipe-art 0.5.18 added Qwen3.5 Megatron support with module-level imports from megatron.core and megatron.bridge that crash when megatron isn't installed, even when using the Unsloth (non-Megatron) backend. Added a lightweight stub that injects placeholder modules into sys.modules in the training subprocess so the imports succeed. The stub classes are never instantiated at runtime.
