Guide users through Cosmos3 installation, environment setup, checkpoint downloading, and verification. Use when the user asks "how do I install cosmos3", "how do I set up the environment", "how do I download checkpoints", "how do I use Docker", or any question about getting the package running for the first time.
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
# Cosmos3 Setup ## When to use this skill - Use when a user wants to install Cosmos3 or set up a development environment - Use when a user asks about system requirements, CUDA versions, or GPU compatibility - Use when a user needs to download model checkpoints or configure HuggingFace auth - Use when a user wants to run Cosmos3 inside a Docker container or NGC container - For errors during setup, hand off to the **cosmos3-env-troubleshoot** skill ## Path convention All paths below are relative to the cosmos3 package root (`../../../` from this skill file). All `uv run` / `python` commands should also be run from there. ## Where to find answers The canonical setup reference is `docs/setup.md`. The README (`README.md` § Setup) has the shortest quickstart. | User question | Go to | | ------------------------------------------------------ | -------------------------------------------------------------------- | | What are the system requirements? | `docs/setup.md` § System Requirements | …

How to install
mdr add nvidia/cosmos-framework/cosmos3-setup@sha256:0ff10d62d1f28b56The line at the top of this page pins the label git:20261024.bf492fe, 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.
