Distributed Python dataframes and machine learning with Livebook and Elixir

Livebook, Elixir's computational notebook platform, now features full Python integration funded by NGI0 Commons Fund. Key additions include reproducible Python environments via uv, Python cells with autocompletion and documentation on hover, zero-copy Apache Arrow data transfers between Elixir and Python, distributed Python execution using Erlang's distribution model with a distributed garbage collector, and support for spawning Python/Elixir workloads across Kubernetes and Fly.io clusters via FLAME integration. Developers can load data in Elixir and manipulate it with Polars or Pandas in Python, pass remote object references without copying, and scale workflows using Elixir's fault-tolerance primitives.
