Extensions

ezmsg uses Python namespace packages to provide a modular ecosystem of extensions. Namespace packages allow multiple independently distributed packages to share a common namespace (ezmsg.*), so you can install only what you need while keeping imports consistent.

For example, installing ezmsg-sigproc makes the ezmsg.sigproc module available:

pip install ezmsg-sigproc

from ezmsg.sigproc.butterworthfilter import ButterworthFilter

Each extension is a separate package with its own dependencies, versioning, and release cycle. This keeps the core ezmsg package lightweight while allowing the ecosystem to grow.
