Elyra

Elyra is a set of AI-centric extensions to JupyterLab Notebooks.

Elyra currently includes the following functionality:

• Visual Pipeline Editor
• Ability to run a notebook, Python or R script as a batch job
• Reusable Code Snippets
• Hybrid runtime support based on Jupyter Enterprise Gateway
• Python and R script editors with local/remote execution capabilities
• Python script navigation using auto-generated Table of Contents
• Python script integrated debugger (Experimental)
• Notebook navigation using auto-generated outlines using Table of Contents
• Language Server Protocol integration
• Version control using Git integration

The Elyra Getting Started Guide includes more details on these features. A version-specific summary of new features is located on the releases page.

Try Elyra

Using container images

You can also try Elyra by running one of the container images from Docker Hub or quay.io:

• elyra/elyra:latest has the latest released version installed.
• elyra/elyra:x.y.z has a specific version installed.

Note: You can also build a container image from the main branch ("dev build") to try out features that have not been released yet.

To run one of the container images, issue the following command, specifying a tag of your choice.

docker run -it -p 8888:8888 elyra/elyra:dev jupyter lab --debug

To make a local directory containing your Notebooks (e.g. ${HOME}/opensource/jupyter-notebooks/) available in your docker container, you can use a mount command similar to the following:

docker run -it -p 8888:8888 -v ${HOME}/opensource/jupyter-notebooks/:/home/jovyan/work -w /home/jovyan/work elyra/elyra:dev jupyter lab --debug

These should produce output similar to that below, where you can then find the URL to be used to access Elyra in your local browser.

    To access the notebook, open this file in a browser:
        file:///home/jovyan/.local/share/jupyter/runtime/nbserver-6-open.html
    Or copy and paste one of these URLs:
        http://4d17829ecd4c:8888/?token=d690bde267ec75d6f88c64a39825f8b05b919dd084451f82
     or http://127.0.0.1:8888/?token=d690bde267ec75d6f88c64a39825f8b05b919dd084451f82

Refer to the installation documentation for details.

Installation

For detailed information refer to the installation documentation.

Prerequisites :

• Node.js 18+
• Python 3.8+
• Miniconda (optional)

Install current release (for JupyterLab 3.x)

The current release version is displayed at the top of this page.

• Install from PyPI

  pip3 install --upgrade "elyra[all]"

• Install from conda-forge

  conda install -c conda-forge "elyra[all]"

Install older release

Installation instructions and JupyterLab support vary by release. Note that a JupyterLab build is required. Installation instructions are located in the release-specific documentation, which can be accessed by selecting a specific version.

Elyra 3.1 < 3.7 (JupyterLab 3.x)

• Install from PyPI

  pip3 install --upgrade "elyra[all]>=3.1.0" && jupyter lab build

• Install from conda-forge

  conda install -c conda-forge "elyra[all]>=3.1.0" && jupyter lab build

Elyra 2.0 < 3.1 (JupyterLab 3.x)

• Install from PyPI

  pip3 install --upgrade "elyra>=2.0.1" && jupyter lab build

• Install from conda-forge

  conda install -c conda-forge "elyra>=2.0.1" && jupyter lab build

Verify Installation

Run the following commands to verify the installation. Note that in the example output below the [version] placeholder is displayed instead of an actual version identifier, which might change with every release.
