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]

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

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.
