Compatibility

With Jupyter

status	jupyterlite-pyodide-kernel	jupyterlite-core	jupyterlab	notebook	retrolab
pre	0.5.*	>=0.5,<0.6	>=4.3.0,<4.4	>=7.3.0,<7.4	-
stable	0.4.*	>=0.4,<0.5	>=4.2.0,<4.3	>=7.2.0,<7.3	-

stable	0.1.*	>=0.1,<0.2	>=3.5,<3.6	-	>=0.3,<0.4

Installing the matching version of JupyterLab with your package manager can help ensure matching labextension assets and kernel dependencies, even though this kernel does not yet work in a full, jupyter_server-hosted client such as JupyterLab or Notebook.

Install

To install the Pyodide kernel labextension and the CLI addons for jupyter lite, run:

pip install jupyterlite-pyodide-kernel

or with conda, mamba, micromamba, etc.

conda install -c conda-forge jupyterlite-pyodide-kernel

For more options see the development install or contributing guide.

Usage

Build a JupyterLite site:

jupyter lite build

Some new CLI options are also available:

jupyter lite --help

This should show something like this:

  --piplite-wheels=<typedtuple-item-1>...
      Local paths or URLs of piplite-compatible wheels to copy and index
      Default: ()
      Equivalent to: [--PipliteAddon.piplite_urls]
  --pyodide=<Unicode>
      Local path or URL of a pyodide distribution tarball
      Default: ''
      Equivalent to: [--PyodideAddon.pyodide_url]

⚠️ The documentation for advanced configuration is available from the main JupyterLite documentation site:

• configuring
• command line interface

Uninstall

To remove the extension, run:

pip uninstall jupyterlite-pyodide-kernel  # or however you installed it

Prerelease Versions

To install pre-release versions with pip:

pip install --upgrade --pre jupyterlite-pyodide-kernel

Or, similarly for the conda ecosystem, for alpha packages:

conda install \
  -c conda-forge/label/jupyterlite_core_alpha \
  -c conda-forge/label/jupyterlite_pyodide_kernel_alpha \
  -c conda-forge \
  jupyterlite-pyodide-kernel

Note: _beta and _rc packages would follow a similar channel naming convention

Development Install

Below is an short overview of getting up and running quickly. Please see the contributing guide for full details.

Development Requirements

Recommended a Python virtual environment provided by a tool of choice, e.g. one of:

• virtualenv
• mamba
• conda

Ensure the local development environment has:

• git
• nodejs 20
• python >=3.8

Development Quick Start

git clone https://github.com/jupyterlite/pyodide-kernel
cd pyodide-kernel
npm run quickstart

Then, serve the built demo site, documentation, and test reports with Python's built-in HTTP server:
