scipy.fft.skip_backend(backend)[source]#

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.

Examples

import scipy.fft as fft fft.fft([1]) # Calls default SciPy backend array([1.+0.j]) with fft.skip_backend('scipy'): # We explicitly skip the SciPy backend ... fft.fft([1]) # leaving no implementation available Traceback (most recent call last): ...
