# jnc

jnc is a **fast, reproducible package manager for NVIDIA Jetson**, built on the conda ecosystem. It provides workspace management, dependency resolution, task running, and environment isolation — purpose-built for edge AI and embedded Linux development on Jetson hardware.

<Note>
  jnc currently supports **Jetson Orin Nano** with **JetPack 6**. Support for additional Jetson modules and JetPack versions is coming soon.
</Note>

jnc is inspired by and built on the [pixi](https://pixi.sh) codebase. Learn more on our [acknowledgements](/acknowledgements) page.

## Quick Demo

Detect your Jetson hardware:

```bash theme={null}
jnc probe
```

Set up a workspace for ML development:

```bash theme={null}
jnc init my-jetson-app
cd my-jetson-app
jnc add python pytorch cuda-toolkit opencv
jnc run python -c "import torch; print(f'CUDA available: {torch.cuda.is_available()}')"
```

Install tools globally:

```bash theme={null}
jnc global install gh ripgrep btop
```

## Available Software

jnc defaults to [conda-forge](https://conda-forge.org/), the largest community-driven conda package repository with over **30,000 packages**. Key packages for Jetson development:

* **ML/AI**: `pytorch`, `tensorflow`, `onnxruntime`, `scikit-learn`, `numpy`, `pandas`
* **Computer Vision**: `opencv`, `pillow`, `torchvision`
* **CUDA**: `cuda-toolkit`, `cudnn`, `cutensor`
* **Python**: `python`, `jupyterlab`, `ipython`
* **C/C++**: `cmake`, `ninja`, `gcc`, `boost`
* **CLI Tools**: `git`, `gh`, `ripgrep`, `make`, `curl`
