Project team round

Here we discuss topics that need broader attention, for example questions that came up but are outside a single project's scope, larger planned changes/PRs that affect all teams or pending work that is blocked by external factors.

Go to the Project boards.

In-depth discussion

Model example deployments

• some astrocyte examples are currently failing due to a mismatch between deployed NEST versions and NEST examples.
• dependencies require releases. referring to master is very unstable.

Updates for NEST's Python user interface

• discussions at the Bernstein Conference 2024 have advanced our idea of the next generation PyNEST API
• some use-cases have been played through using a combination of more object orientation in NEST models and Python standard library features. This looks very promising.

Representation of hierarchical models in the Python API (#3322)

• @heplesser presented an example how to handle hierarchical model descriptions in pandas.DataFrames and build the network by multi-level indexing into the array
• Currently some output in Jupyter is hindered by a lookup in NodeCollection.__getattr__()
