scverse-backends 0.0.2

Pluggable backend dispatch for scverse and scientific Python host libraries

scverse-backends

⚠️ Under active development. APIs may shift.

The default plugin & dispatch mechanism for scverse. Any host library decorates its public functions with @backend_dispatch; any backend — GPU, distributed, JAX, PyTorch, anything — plugs in via a Python entrypoint and gets picked up automatically.

Want to add a PyTorch backend, a JAX backend, your own custom one? You don't need a PR against the host. Ship a package that exposes a module or object with name, aliases, and host-named callables, register it as an entry point, and users install it next to the host. That's the whole contract.

import example_host as eh

with eh.settings.use_backend("accelerated"):
    eh.some_function(data)

Status

• Built from backend-dispatch prototypes in scverse host integrations.
• Concrete backend aliases belong in host integrations, not in this infrastructure package.
• Goal: host libraries depend on this package and stop re-rolling their own dispatch.
