Dev Sprint: Getting the PyMC v4.0 Release Out#
The v4.0 release of the PyMC library was officially announced on June 6, 2022. To achieve this milestone, the PyMC team planned a week-long online sprint beginning May 30, 2022. The goal was to complete remaining issues on the v4.0 release. But, mainly it was to finalize the documentation and update the website for PyMC.
And all 3 websites had separate navigation bars and it was confusing for the users, maybe for the library maintainers too?
This Dev sprint was held on the new PyMC Discord server which easily enables sharing video, camera and screen share and provides an easy way to hop between “channels”.
We shared the sprint events on our new PyMC Online Meetup to involve experienced contributors in the community as well. We had a mix of core contributors and newcomers, which is a great combination, as it enables us to be productive, but also to foster the new generation of core developers. The following team members attended, from various locations around the world:
Thomas Wiecki (Germany)
Ricardo Vieira (Romania)
Christian Luhmann (New York, USA)
Alex Andorra (France)
Michael Osthege (Germany)
Oriol Abril Pla (Finland)
Chris Fonnesbeck (Nashville, USA)
Osvaldo Martin (Argentina)
Maxim Kochurov (Moscow, Russia)
Reshama Shaikh (New York, USA)
The PyMC project also have begun the 2022 Google Summer of Code (GSOC) program and the following GSOC folks joined:
Connor Hassan (Australia)
Purna Chandra Mansingh (India)
Danh Phan (Australia)
Larry Dong (Canada)
A number of contributors joined from the community:
Rob Zinkov (Germany)
There were lots of people throughout the week, and it is likely we are forgetting some folks. If we forgot you, let us know!
Highlight Achievements During the Sprint#
Below are a list of highlights that the PyMC development team is excited to share.
The new website at https://t.co/tbR03EYZl5 is indeed a major improvement. The docs team, lead by @OriolAbril completely overhauled it. It even has an interactive demo of PyMC running in the browser with @pyodide 🤯. https://t.co/yDkLfPmo9C— Thomas Wiecki (@twiecki) June 6, 2022

Hierarchical Modeling with LKJ Prior#
Tomas Capretto wrote an article on Hierarchical modeling with the LKJ (Lewandowski-Kurowicka-Joe) prior in PyMC
#PyMC version 4 is out and we're all excited about the massive improvements. In this new blogpost, I explore how to use `LKJCholeskyCov` and `LKJCorr` to place a prior on a correlation matrix in hierarchical modeling. Want to have a look?! https://t.co/08LULKa5XL— Tomás Capretto (@CaprettoTomas) June 13, 2022
