Installation

First, install JupyterLab and pymapd as well the jupyterlab-omnisci Python package:

conda install -c conda-forge jupyterlab pymapd

pip install \
    jupyterlab-omnisci \
    git+https://github.com/Quansight/ibis.git@omnisci-sample \
    altair

Then install the jupyterlab-omnisci JupyterLab extension.

jupyter labextension install jupyterlab-omnisci

Then launch Jupyter Lab:

jupyter lab

Bleed Edge Installation

If you would like to get some of geographic use cases to work, like those in ./notebooks/OmniSci Vega Tutorial.py, you also have to use the latest beta versions of Altair and Vega.

First install the latest Altair:

pip install    git+https://github.com/jakevdp/altair.git@vl3-rc8

Then tell JupyterLab to use a later version of Vega Lite, by adding a resolution to the ./staging/package.json file in the jupyterlab Python package.

This works on a Mac:

open $(python -c 'import os; import jupyterlab; print(os.path.dirname(jupyterlab.__file__))')/staging/package.json

Add resolutions key:

{
    "resolutions": {
        "vega-embed": "3.28.0"
    },
    "name": "@jupyterlab/application-top",
    "version": "0.19.1",
    ...

Then rebuild JupyterLab:

jupyter lab build

Then you can input an SQL query and hit the triangle to see the results:

To set a default connection that will be saved and used for new editors, go to Settings > Set Default Omnisci Connection....

Getting started with Ibis

Once you have set a default connection, you can run the Inject Ibis OmniSci Connection command to prefil a cell to connect to it with Ibis.
