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
