Examples

>>> import mindspore
>>> import numpy as np
>>> from mindspore import Tensor, ops
>>> is_nan = ops.IsNan()
>>> x = Tensor(np.array([np.log(-1), 1, np.log(0)]), mindspore.float32)
>>> output = is_nan(x)
>>> print(output)
[ True False False]
>>> x = Tensor(2.1, mindspore.float64)
>>> output = is_nan(x)
>>> print(output)
False
