Pre-release

This release is a pre-release and may not be stable for production use.

opspec

Describe image-processing ops so plugins, runners and hosts can share them.

opspec is a small Python package with no dependencies beyond the standard library. It defines two things:

  • Ops: how a plugin author declares what an op takes and returns (for example "a 2D image, numpy only").
  • Runners: the interface a runner implements to run those ops, whether in the same process, in another environment, or on a GPU.

Hosts (napari, CellProfiler, a notebook) read the op declarations and hand ops to a runner.

Install

opspec lives in the scikit-ops repository. Not on PyPI yet:

pip install "opspec @ git+https://github.com/apposed/scikit-ops#subdirectory=opspec"

Docs

  • 0001 — what an OpSpec is: @op, roles, ImageOf, Axes
  • 0002 — what a runner does: the Runner and Builder protocols
  • 0003 — where opspec and scikit-ops' spec code differed, and which way each went
