Pixi kernel

Per-directory Pixi environments with multi-language Jupyter kernels.

Pixi kernel supports Jupyterlab 4, Python 3.9+ and Pixi 0.30.0+ using pyproject.toml and pixi.toml configurations.

Disclaimer: This project is not affiliated with Pixi, and not an official Pixi plugin.

Quick Start

This assumes you want a Python kernel. For other languages, check the Kernel support table and replace ipykernel with the desired kernel package.

1. Install Pixi and pixi-kernel alongside JupyterLab using your favorite package manager.
2. Restart JupyterLab.
3. Create a new directory and initialize a Pixi project with pixi init and pixi add ipykernel.
4. Restart the kernel and you are good to go.

See the Pixi docs for more information on how to use Pixi.

Kernel support

Pixi kernel supports the following kernels:

Language	Kernel	Package name
Python	IPython Kernel	ipykernel
R	IR Kernel	r-irkernel

Support for other kernels and languages can be added by opening an issue or a pull request, see CONTRIBUTING.

Pixi environments

Pixi kernel supports multiple Pixi environments in a single Pixi project. To select a specific environment, use JupyterLab property inspector, save your notebook and restart your kernel.

Limitations

Pixi kernel only works with the default environment in VSCode.
