scipy.fft.set_global_backend

scipy.fft.set_global_backend(backend)

Sets the global fft backend

The global backend has higher priority than registered backends, but lower priority than context-specific backends set with set_backend.

Parameters

backend: {object, ‘scipy’}

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

Raises

ValueError: If the backend does not implement numpy.scipy.fft

Notes

This will overwrite the previously set global backend, which by default is the SciPy implementation.
