mindspore.ops.IsNan

class mindspore.ops.IsNan[source]

Determines which elements are NaN for each position.

Refer to mindspore.ops.isnan() for more details.

Inputs:

x (Tensor) - The input tensor. \((N, *)\) where \(*\) means, any number of additional dimensions.

Outputs:

Tensor, has the same shape of input, and the dtype is bool.

Supported Platforms:

Ascend GPU CPU

Examples

>>> is_nan = ops.IsNan()
>>> x = Tensor(np.array([np.log(-1), 1, np.log(0)]), mindspore.float32)
>>> output = is_nan(x)
>>> print(output)
