Installation & Dependency Groups¶

NeMo Skills provides two installable packages:

nemo-skills (root) -- full install with CLI, cluster orchestration, all benchmarks
nemo-skills-core (core/ subdirectory) -- lightweight runtime only

Default installation¶

pip install nemo-skills gives you everything (inference, evaluation, CLI, cluster orchestration, benchmarks):

pip install git+https://github.com/NVIDIA-NeMo/Skills.git
# or, from a local clone:
pip install -e .

Lightweight installation¶

If you only need inference, evaluation, and tool calling (no cluster orchestration):

pip install "nemo-skills-core @ git+https://github.com/NVIDIA-NeMo/Skills.git#subdirectory=core"
# or, from a local clone:
pip install -e core/

Extras (dependency groups)¶

Extra	Requirements file	What it provides
`core`	`core/requirements.txt`	Agent runtime: inference, evaluation, tool calling (MCP), prompt formatting, math/code grading. No cluster orchestration.
`pipeline`	`requirements/pipeline.txt`	CLI (`ns` command), cluster management, experiment tracking (`nemo_run`, `typer`, `wandb`).
`dev`	`requirements/common-tests.txt`, `requirements/common-dev.txt`	Development and testing tools (`pytest`, `ruff`, `pre-commit`).
