dpnp.any

dpnp.any(x, /, axis=None, out=None, keepdims=False, *, where=True)[source]

Test whether any array element along a given axis evaluates to True.

For full documentation refer to numpy.any.

Returns:: out – An array with a data type of bool containing the results of the logical OR reduction.
Return type:: dpnp.ndarray

Limitations

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

dpnp.all: Test whether all elements along a given axis evaluate to True.

Notes

Not a Number (NaN), positive infinity and negative infinity evaluate to True because these are not equal to zero.

Examples

>>> import dpnp as np
>>> x = np.array([[True, False], [True, True]])
>>> np.any(x)
array(True)

>>> np.any(x, axis=0)
array([ True,  True])

>>> x2 = np.array([0, 0, 0])
>>> np.any(x2)
array(False)

>>> x3 = np.array([1.0, np.nan])
>>> np.any(x3)
array(True)
