jupyterlite-pyodide-kernel

A Python kernel for JupyterLite powered by Pyodide,

Requirements

• python >=3.8

Compatibility

status	jupyterlite-pyodide-kernel	jupyterlite-core	jupyterlab	notebook	retrolab
stable	0.2.*	>=0.2,<0.3	>=4.0.7,<5	>=7.0.5,<8	-
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]

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
