BackendManager

class BackendManager

Bases: object

Manager for template matching backends.

This class serves as an interface to various computational backends (e.g., CPU, GPU). It allows users to seamlessly swap between different backend implementations while preserving the consistency and functionality of the API. Direct attribute and method calls to the manager are delegated to the current active backend.

Attributes:

_BACKEND_REGISTRYdict

A dictionary mapping backend names to their respective classes or instances.

_backendinstance of MatchingBackend

An instance of the currently active backend.

_backend_namestr

Name of the current backend.

_backend_argsDict

Arguments passed to create current backend.

Notes

The backend has to be reinitialzed when using fork-based parallelism.

Examples

>>> from tme.backends import backend
>>> backend.multiply(arr1, arr2)
# This will use the default NumpyFFTWBackend's multiply method

>>> backend.change_backend("pytorch")
>>> backend.multiply(arr1, arr2)
# This will use the pytorchs multiply method

>>> backend.available_backends()
# Backends available on your system

Methods

BackendManager.add_backend(backend_name, ...)	Adds a custom backend to the registry.
BackendManager.available_backends()	Determines importable backends.
BackendManager.change_backend(backend_name, ...)	Change the backend.
