kermt-pretrain-scratch SKILL.md skillA
kermt-pretrain-scratch from nvidia/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nvidia/skills/kermt-pretrain-scratch@git:20260915.2cd3507Pins git:20260915.2cd3507 in mdr.lock. Pin the fingerprint instead.

Pretrain a fresh KERMT model from scratch on a user-provided corpus. Builds a new vocabulary from the corpus, instantiates the model architecture from defaults, and launches pretrain_ddp.py inside the kermt container (detached for long runs). Unlike kermt-continue-pretrain, no starting checkpoint is loaded — the model is randomly initialized.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# kermt-pretrain-scratch Pretrain a brand-new KERMT model from scratch on a user-provided corpus. Useful when you want to retrain a model on a custom chemistry domain rather than extending one of the released checkpoints. **Significantly more expensive than `kermt-continue-pretrain`** — no warm start, so the loss curves need to descend from scratch over many epochs. ## Skill and runtime paths Set `SKILL_DIR` to the absolute path of this installed skill directory. Export `KERMT_REPO` as the absolute path to the KERMT checkout used for model execution. The bundled container helper mounts that checkout at `/workspace` and this skill at `/skill` (read-only). Commands inside the container use `/skill/scripts/`; defaults are bundled in `config/`. ## Hardware requirements Same as `kermt-continue-pretrain`: - **GPUs**: 1–N CUDA-capable. The runner auto-detects via `torch.cuda.device_count()`; `--gpus 0,2` overrides. Single-GPU fallback: `--batch_size 32 --save_interval 500`. Multi-GPU keeps defaults (`--batch_size 256` etc.). Note: `--gpus N` uses **torch.cuda** indexing, which can differ from `nvidia-smi`'s display order on multi-GPU hosts …

How to install
mdr add nvidia/skills/kermt-pretrain-scratch@sha256:33f9eeb51b365351The line at the top of this page pins the label git:20260915.2cd3507, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
