Use when Cosmos3 setup, fetch, inference, CUDA, uv, Docker, Hugging Face, GitHub, NGC, or checkpoint staging fails in NPA or in an upstream Cosmos framework checkout.
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.

# Cosmos3 Environment Troubleshooting ## Source And Attribution Adapted from NVIDIA cosmos-framework `skills/atomic/cosmos3-env-troubleshoot/SKILL.md`. Copyright (c) 2026 NVIDIA CORPORATION & AFFILIATES. Used under OpenMDW-1.1. See `skills/LICENSE-NVIDIA-COSMOS3-OPENMDW-1.1` and `skills/NOTICE-NVIDIA-COSMOS3`. ## When To Use Use this skill for import errors, missing Python packages, CUDA or torch failures, Docker GPU runtime problems, failed source clones, Hugging Face 401s, NGC credential errors, and inference runtime tracebacks. For "where is this file or config" questions, use `skills/atomic/cosmos3-codebase-nav/SKILL.md`. ## First Rule Never print or commit secrets. Token-bearing values include `GITHUB_TOKEN`, `HF_TOKEN`, `HUGGING_FACE_HUB_TOKEN`, `NGC_API_KEY`, AWS keys, and any env var selected through `NPA_COSMOS3_*_TOKEN_ENV`. ## NPA Diagnostic Ladder 1. Confirm the NPA command surface: ```bash npa/.venv/bin/npa workbench cosmos --help ``` `check` and `fetch` should be present. `skill` and `skills` should not be present. 2. Run a redacted access check: ```bash npa/.venv/bin/npa workbench cosmos check --output json ``` …

How to install
mdr add nebius/nebius-physical-ai/cosmos3-env-troubleshoot@sha256:a9b46926a46b1104The line at the top of this page pins the label git:20260906.a7b9ddb, 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.
