Installation

The Elyra JupyterLab extensions can be installed from PyPI, conda, or from source code.

Prerequisites

JupyterLab dependencies:

  • Elyra >= 2.0.0 requires JupyterLab 3.x
  • Elyra < 2.0.0 requires JupyterLab 2.x
  • Elyra == 0.10.x requires JupyterLab 1.x

The instructions below are installing the latest release.

Packaging

Prior to version 3.1, the elyra package included all dependencies. Subsequent releases allow for selective dependency installation:

  • elyra - install the Elyra core features
  • elyra[all] - install core features and all dependencies
  • elyra[kfp-tekton] - install the Elyra core features and support for Kubeflow Pipelines on Tekton
  • elyra[gitlab] - install the Elyra core features and GitLab support for Apache Airflow pipelines
  • elyra[kfp-examples] - install the Elyra core features and Kubeflow Pipelines custom component examples

pip

If you use pip, install Elyra with:

pip3 install --upgrade "elyra[all]"

If desired, you can install these Elyra extensions independently:

   pip3 install --upgrade elyra-pipeline-editor-extension

   pip3 install --upgrade elyra-code-snippet-extension

   pip3 install --upgrade elyra-code-viewer-extension

   pip3 install --upgrade elyra-python-editor-extension

   pip3 install --upgrade elyra-r-editor-extension

   pip3 install --upgrade elyra-scala-editor-extension

conda

If you use conda, install Elyra with:

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

NOTE: The Elyra packaging process was changed in version 3.1.0. The Kubeflow Pipelines on Tekton dependency is no longer installed by default. To install this dependency, you must specify elyra[all] or elyra[kfp-tekton].

You can also install the Pipeline editor, Code Snippet, Code Viewer, or Script editor extensions individually:

conda install -c conda-forge elyra-pipeline-editor-extension

conda install -c conda-forge elyra-code-snippet-extension

conda install -c conda-forge elyra-code-viewer-extension

conda install -c conda-forge elyra-python-editor-extension

conda install -c conda-forge elyra-r-editor-extension

NOTE: The R Editor extension is not yet available on conda-forge or pip package manager.

Build from source

To build Elyra from source code follow the instructions in developer guide.

Verify Installation

To verify an Elyra installation review the installed server extensions and lab extensions.

Verify the server extensions

Verify that the elyra extension is installed.

Verify the lab extensions

Verify that the elyra labextensions are installed.

Docker

If you have Docker installed, you can use JupyterLab and Elyra by running one of the ready-to-run container images:

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

Pulling Elyra container images

Images can be pulled from Docker Hub

docker pull elyra/elyra:dev

or quay.io

docker pull quay.io/elyra/elyra:dev

Running Elyra container images

Invocation example 1: Run Elyra v3.4.0 in a Docker container. All changes are discarded when the Docker container is stopped.

docker run -it -p 8888:8888 elyra/elyra:3.4.0 jupyter lab --debug

Invocation example 2: Run Elyra v3.4.0 in a Docker container and mount the existing local $HOME/jupyter-notebooks/ directory as JupyterLab work directory. This enables you to make existing notebooks and other files available in the Docker container. Only files in this working directory are retained when the Docker container is stopped.

docker run -it -p 8888:8888\
 -v ${HOME}/jupyter-notebooks/:/home/jovyan/work\
 -w /home/jovyan/work\
 elyra/elyra:3.4.0 jupyter lab --debug

Invocation example 3: Same as above. In addition a local directory named ${HOME}/jupyter-data-dir is mounted as the Jupyter data directory in the Docker container, storing all user-defined Elyra metadata artifacts you might create, such as code snippets, runtime configurations, or runtime images.

Note: To start with a clean environment ${HOME}/jupyter-data-dir should refer to an empty directory. To re-use an existing Jupyter data directory from a local installation specify the output of jupyter --data-dir as directory name.

docker run -it -p 8888:8888\
 -v ${HOME}/jupyter-notebooks/:/home/jovyan/work\
 -w /home/jovyan/work\
 -v ${HOME}/jupyter-data-dir:/home/jovyan/.local/share/jupyter\
 elyra/elyra:3.4.0 jupyter lab --debug

Open the displayed URL in your browser to start using JupyterLab and Elyra.

    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
