spark-environment-setup SKILL.md skillA
spark-environment-setup from wshobson/agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add wshobson/agents/spark-environment-setup@git:20260714.baa5bd7Pins git:20260714.baa5bd7 in mdr.lock. Pin the fingerprint instead.

Set up a working ML training/inference environment on NVIDIA DGX Spark (GB10, aarch64, CUDA 13). Use when installing PyTorch/Unsloth/TRL/vLLM on DGX Spark, hitting libcudart or wheel-ABI errors on aarch64, or choosing between NGC containers and bare pip installs.
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
# Spark Environment Setup DGX Spark ships a GB10 Grace Blackwell chip: aarch64 CPU, SM121 GPU, 128GB unified memory, CUDA 13. This is a narrower and younger platform than a standard x86 CUDA 12 box, so package selection and ABI matching matter more than usual — the wheel ecosystem for aarch64 + CUDA 13 is still filling in. ## When to Use This Skill - Setting up a fresh Spark box for training or inference. - Hitting an import error mentioning `libcudart`, a missing symbol, or a wheel that "installed fine but won't load." - A framework install (PyTorch, Unsloth, TRL, vLLM, xformers) fails, hangs, or silently falls back to CPU. - Deciding whether to use an NGC container or bare pip. - Restoring a working setup after an OS reinstall or a base-image update, needing to re-verify from scratch. Each of these accepts the same general fix: match the container/wheel combination to CUDA 13 and SM121, don't fight the ABI. ## Container-First Rule Quick decision, before the detail below: - Standard training/inference work → NGC PyTorch container. - Unsloth-centric fine-tuning → Unsloth container (it ships the pinned Triton/xformers/transformers combination already …

How to install
mdr add wshobson/agents/spark-environment-setup@sha256:4fe4b4328a52dae8The line at the top of this page pins the label git:20260714.baa5bd7, 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.
