SwanDask

This module is a wrapper to the dask-labextension extension. It allows running the backend as a separate process, served via jupyter-server-proxy, instead of a server extension.

We use it to configure the Dask environment, which we want to be different than the process running Jupyter Lab.

The extension will automatically load the environment from the default Python 3 kernel.

Install

pip install swandask

If being served under an LCG release, install the package without any dependency except Jupyter and jupyter-server-proxy. Installing without dependencies doesn't create the entry points. So the extension no longer depends on dask-labextension but this needs to be present. It also requires, and installs, tornado and jupyter-server-proxy.

This extension needs to be installed after its dependency dask-labextension in order to disable the server extension automatically. Otherwise, just disable it manually.
