Elyra extends JupyterLab Notebooks with an AI centric approach.

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
• 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.

Try Elyra

Using Binder

You can try out some of Elyra features using the My Binder service.

Click on a link below to try Elyra, on a sandbox environment, without having to install anything.

• (Latest stable version - see changelog for recent updates)
• (Development version - expect longer image load time due to just-in-time build)

Using Docker

You can also try Elyra by running one of the docker images from Docker Hub:

• elyra/elyra:latest has the latest released version installed.
• elyra/elyra:x.y.z has a specific version installed.
• elyra/elyra:dev is automatically re-built each time a change is committed to the master branch.

The command below starts the most recent development build in a clean environment:

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

Installation

Elyra can be installed from PyPI:

Prerequisites :

• NodeJS 12+
• Python 3.6+

Optional :

• Miniconda

JupyterLab support

NOTE: On November 2020, a new version of PIP (20.3) was released with a new, "2020" resolver. This resolver does not yet work with Elyra and might lead to errors in installation. In order to install Elyra, you need to either downgrade pip to version 20.2.4 pip install --upgrade pip==20.2.4 or, in case you use pip 20.3 (or later), you need to add option --use-deprecated legacy-resolver to your pip install command.

• JupyterLab 3.x is supported on Elyra 2.0.0 and above

  Install Elyra from PyPI ( Elyra >= 3.1.0 ):

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

  Install fom Conda ( Elyra >= 3.1.0 ):

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

  Install Elyra from PyPI ( Elyra < 3.1.0 ):

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

  Install fom Conda ( Elyra < 3.1.0 ):

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

• JupyterLab 2.x is supported on Elyra 1.0.0 and above

  Install from PyPI:

  pip3 install --upgrade "elyra<2.0.0" && jupyter lab build

  Install from Conda:

  conda install -c conda-forge "elyra<2.0.0" && jupyter lab build

• JupyterLab 1.x is supported on Elyra 0.10.x and below
