Signature de la fonction skip_backend

def skip_backend(backend) 

Description

skip_backend.__doc__

Context manager to skip a backend within a fixed scope.

    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):
        ...
    BackendNotImplementedError: No selected backends had an implementation ...
