Dask Heartbeat by Coiled: 2021-04-01

The Dask community is highly distributed with different teams working independently. This is powerful but sometimes makes it hard for people within the community to see everything that is going on. The Dask Heartbeat by Coiled is a monthly publication intended to centralize and broadcast Dask news over the previous four weeks.  

If you want something added to this list either send an e-mail at info@coiled.io, or tweet and tag @dask_dev and we’ll try to include it. Keep reading for the latest updates.

Dask Distributed Summit 

Thanks to everyone who submitted talk, tutorial, and workshop proposals for the Dask Distributed Summit. Stay tuned for an announcement about the conference schedule and don’t forget to register for the summit


Over the last month there have been several releases in the Dask ecosystem. In particular:

Dask monthly community meeting 

Some highlights from the April Dask community meeting:

Dask with PyTorch for large scale image analysis

Nicholas Sofroniew (CZI), Genevieve Buckley recently published a blog post that explores applying a pre-trained PyTorch model in parallel with Dask Array.

Dropped Python 3.6 support

Both Dask and Distributed dropped support for Python 3.6 in version 2021.03.1. This means today Dask and Distributed supports Python 3.7, 3.8, and 3.9.

Dask adds more dependencies

Dask recently added cloudpickle, partd, fsspec, and toolz as required dependencies. Previously these packages were required to use certain functionality in Dask (e.g. Dask delayed), but were upgraded to required dependencies to reduce project maintenance.

The Dask development team maintains commit rights on all of these projects. 

Main branch migration

The Dask community continues migrating the default branch name for its repositories to “main”. Recently the Dask and Distributed repositories were migrated. You can track progress here

Image segmentation with Dask

In a recent blog post, Genevieve Buckley walks through how to create a basic image segmentation pipeline, using the Dask-Image library.
