张宗平	8aeddebce9	test(m4): instruct_check unit tests + unbuffered training scripts ... - tests/test_instruct_check.py: cover load_by_category (bucketing/cap/seed determinism/short-pool/blank-line) and _forecast_list (nested/flat/ dict/garbage). 8 tests pass. - train_stage{1,2}.sh: export PYTHONPATH=src + PYTHONUNBUFFERED=1 so future background runs stream logs live (current stage2 run is block-buffered).	2026-06-30 07:27:03 +00:00
张宗平	bf95ac18e4	feat(m3): stage 1 alignment training script + smoke (T3.2) ... - src/tsmm/train/stage1.py: streams align.jsonl, freeze_llm, trains Encoder+Projector (AdamW lr=1e-4), bs=8/grad_accum=4/ctx=512/BF16, gradient checkpointing + enable_input_require_grads, loss = lm + lambda*InfoNCE (original vs perturbed TS representation), ckpt + tensorboard every 2000 steps. - scripts/train_stage1.sh: wrapper with design defaults. - src/tsmm/data/collator.py: handle JSON null (missing markers) -> NaN -> fill. - .gitignore: /checkpoints/ and data/*.jsonl. - Smoke verified: --max_steps 5 on 64 samples, finite loss, peak 5.52 GB (≤6GB). - 100 tests passing.	2026-06-30 02:22:32 +00:00
