`scipy.fft._backend:skip_backend`

source: build-install/usr/lib/python3.14/site-packages/scipy/fft/_backend.py:176

Signature

def skip_backend(backend)

Summary

Context manager to skip a backend within a fixed scope.

Extended Summary

Within the context of a with statement, the given backend will not be called. This covers backends registered both locally and globally. Upon exit, the backend will again be considered.

Parameters

backend : {object, 'scipy'}: The backend to skip. Can either be a str containing the name of a known backend {'scipy'} or an object that implements the uarray protocol.

Returns

context : uarray._SetBackendContext: Context manager that skips the backend.

Notes

Array API Standard Support

skip_backend is not in-scope for support of Python Array API Standard compatible backends other than NumPy.

See dev-arrayapi for more information.

Examples

import scipy.fft as fft

✓

fft.fft([1])  # Calls default SciPy backend
with fft.skip_backend('scipy'):  # We explicitly skip the SciPy backend
    fft.fft([1])                 # leaving no implementation available

✗
