Summary
This PR syncs
mainintodev, merging 109 commits frommain.Python lines: +35569 / -10794 across 265 files
Files where main's version was taken over the merge
Per the nightly-sync skill, these files have known semantic conflicts where dev's version references args/APIs main has removed:
megatron/training/training.pymegatron/training/initialize.pymegatron/training/utils.pymegatron/training/datasets/data_samplers.pymegatron/core/optimizer/layer_wise_optimizer.pyFiles restored from main
megatron/core/pipeline_parallel/hybrid_cp_schedule.py— needed by main'sHybridCPDataLoaderWrapperSpecial-case merges
megatron/core/datasets/data_schedule.py— kept dev's classes (BasePackingScheduler,DpBalancedScheduler,DefaultDynamicCPScheduler,wrap_data_iterator,get_batch_on_this_rank_for_sequence_packing) and appended main'sHybridCPDataLoaderWrapperclass. Added imports forAny,List, andBalancedCPSchedulerto support both class sets.Files deleted from main accepted
These were intentionally removed on main (PR #4207, #4322, etc.):
megatron/legacy/model/__init__.pymegatron/legacy/model/transformer.pytools/checkpoint/loader_legacy.pytools/checkpoint/loader_llama_mistral.py(Plus the rest of
megatron/legacy/model/*automatically deleted by the merge.)Files explicitly NOT taken from main
Per the skill, the dependency-management triple stays on dev:
pyproject.tomluv.lockdocker/Dockerfile.ci.dev.github/CODEOWNERSleft at dev's version (verified empty diff).Git source reconciliation
pyproject.toml[tool.uv.sources]: dev includesfast-hadamard-transform(not on main) and a differentnvidia-resiliency-extrevision. Dev'snvrx.pyusesgetattr(...)for the symbols main expects, so dev's revision is compatible.Test plan
