dpnp.isinf

dpnp.isinf(x, /, out=None, *, where=True, order='K', dtype=None, subok=True, **kwargs)

Test element-wise for positive or negative infinity.

For full documentation refer to numpy.isinf.

Limitations

Parameters x is only supported as either dpnp.ndarray or dpctl.tensor.usm_ndarray. Parameters where, dtype and subok are supported with their default values. Otherwise the function will be executed sequentially on CPU. Input array data types are limited by supported DPNP Data types.
