From 01938c856420e52dd4d4ec6cbb47db7a39397b5b Mon Sep 17 00:00:00 2001 From: Cemil ILIK Date: Mon, 11 May 2026 11:46:59 +0300 Subject: [PATCH 1/3] =?UTF-8?q?fix(notebooks):=20end-to-end=20Colab=20usab?= =?UTF-8?q?ility=20sweep=20=E2=80=94=20torchao,=20config=5Ftemplate,=20saf?= =?UTF-8?q?ety=20fallback?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit End-to-end audit of all 10 notebooks identified three real issues that would surface as cryptic runtime errors on a fresh Colab session: 1. **torchao 0.10 vs peft >=0.16 conflict (7 notebooks).** Colab base image ships ``torchao==0.10``, but modern ``peft.PeftModel.from_pretrained`` requires ``torchao>=0.16``. Each affected notebook's Step 7/8 compare-base-vs-fine-tuned cell crashed with ``ImportError: Found an incompatible version of torchao``. Added a one-line ``pip install -q --upgrade 'torchao>=0.16.0'`` to the install cell of every notebook that loads a LoRA adapter via ``PeftModel.from_pretrained``: ``quickstart_sft``, ``dpo_alignment``, ``grpo_reasoning``, ``kto_binary_feedback``, ``multi_dataset``, ``synthetic_data_training``, ``galore_memory_optimization``. 2. **Missing ``config_template.yaml`` in ``post_training_workflow.ipynb``.** The first executable cell calls ``forgelm --config config_template.yaml --fit-check`` but the file is bundled in the repo, not the wheel — so a fresh Colab session fails with ``Config file not found``. Added a ``wget`` step to the install cell that pulls the file from ``main``. 3. **Silent failure in ``safety_evaluation.ipynb`` Step 3.** The prompt- library bootstrap ran ``!git clone … 2>/dev/null`` and silently set ``prompts_dir`` to a non-existent path on clone failure; the fallback branch claimed to "create sample prompts" but no creation actually happened. The next cell then wrote that broken path into the YAML config, training crashed with ``FileNotFoundError``. Rewrote Step 3 as a three-tier fallback: in-package path → git clone (with ``subprocess.run`` so the return code is checked) → ``urllib`` single-file wget → inline 3-prompt smoke set with a loud warning. Every branch ends with a populated ``prompts_dir`` that downstream cells can rely on. Also dropped the stale ``(Phase 10)`` parenthetical from the ``post_training_workflow.ipynb`` title — phase numbering was consolidated into ``docs/roadmap/completed-phases.md`` in v0.5.7. Verified: all 10 notebooks remain valid nbformat v4 JSON, all six doc guards pass (anchor-resolution, bilingual-parity, CLI-help consistency, wizard-defaults, no-analysis-refs, no-unguarded-sys-modules-pop). No production code touched.

All four fixes are real (notebook claims something the code doesn't do, or a demo path that fails on a fresh Colab session) plus one cosmetic comment placement. 1. **`galore_memory_optimization.ipynb` — doc/code drift on what GaLore actually does in ForgeLM.** The original Cell 0 + Cell 8 markdown described the academic GaLore paper ("updates ALL weights", "no adapter files at inference", "full-parameter training"). But the config has a required `lora:` block (Phase 19 library-API invariant), and Cell 7 loads the result via `PeftModel.from_pretrained` — meaning the actual ForgeLM behaviour is "GaLore as the optimizer **on top of** LoRA". Rewrote the markdown to describe what the notebook actually does (LoRA + 8-bit GaLore-projected Adam), with an explicit "different from the academic paper" callout so readers comparing against the upstream `galore-torch` README aren't blindsided. 2. **`grpo_reasoning.ipynb` — correctness reward was advertised but never wired.** Cell 9 markdown said "Responses are scored by a reward function (correctness for math)", but the demo's `math_prompts.jsonl` had no `gold_answer` field, so ForgeLM's `_dataset_has_gold_answers` short-circuited and only the always-on `combined_format_length_reward` ran. Added `gold_answer` to each prompt + updated Cell 9 to describe the actual additive reward stack (format + math correctness) — the demo now matches its own advertisement, and the trained model has a real correctness signal to learn from. 3. **`safety_evaluation.ipynb` — Llama-Guard-3-8B gating + VRAM un-warned.** The default `evaluation.safety.classifier` is `meta-llama/Llama-Guard-3-8B` — gated on HF Hub (license must be accepted) and ~16 GB in FP16 (right at a free Colab T4's ceiling). The notebook didn't mention either gotcha, so Step 6 would fail mid-training with a 401 (no token) or OOM (T4 too tight). Inserted a Pre-flight markdown + sanity-check cell pair AFTER Cell 2 (GPU check) that documents both requirements and verifies `HF_TOKEN` is in the environment before training kicks off. Operator gets a clear pre-Step-6 warning instead of a cryptic mid-run crash. 4. **`post_training_workflow.ipynb` Cell 7 — programmatic inference path assumed `./checkpoints/final_model` exists.** A fresh-kernel "Run All" failed with `FileNotFoundError` because the cell hard- coded the local path that quickstart_sft would have produced. Now the cell checks for the local path first, falls back to the base `HuggingFaceTB/SmolLM2-135M-Instruct` HF Hub ID with a clear "fallback for demo" log if the local path is missing. The demo runs end-to-end on a clean session; users who did train get their own adapter exercised automatically. 5. **`quickstart_sft.ipynb` Cell 1 — cosmetic.** The "Verify installation" comment was orphaned between two `!pip install` lines after the round-3 torchao patch. Moved it back to its intended spot directly above `!forgelm --version`. Verified: all 10 notebooks remain valid `nbformat v4` JSON.

Gemini's "missing json import in network-failure fallback" claim was a false alarm — `import json` is on Cell 3 line 2, verified. - **`post_training_workflow.ipynb` install cell** — wget URL pinned from `main` to the `v0.5.7` tag so the downloaded `config_template.yaml` always matches the pinned wheel version. A drift on `main` (new Pydantic field, renamed key) would otherwise bypass the installed schema and trip on Step 3's `--fit-check`. - **`safety_evaluation.ipynb` Step 3 — partial-clone retry.** A previous interrupted run could leave `/tmp/forgelm_prompts/` on disk without `configs/safety_prompts/`. The old logic skipped the `git clone` (because the directory existed) but then failed the subdir check and silently fell through to wget. Now: if the existing clone lacks the expected subdir, it's `shutil.rmtree`'d and the clone is re-attempted before any fallback. Also pinned the wget URL to `v0.5.7` for the same reason as the post_training fix. - **`safety_evaluation.ipynb` pre-flight — Colab Secrets path.** Colab stores tokens in `google.colab.userdata`, not `os.environ`, so the previous "no HF_TOKEN in env" warning would fire even when the operator had correctly set HF_TOKEN as a Colab Secret. Pre- flight now queries `userdata.get()` for `HF_TOKEN` / `HUGGING_FACE_HUB_TOKEN` / `HUGGINGFACE_TOKEN`, mirrors any found value into `os.environ` (so downstream HF libs see it), and only emits the warning if both sources come back empty.
