mindspore.ops.IsInf

class mindspore.ops.IsInf[source]

Determines which elements are inf or -inf for each position

outi={ if xi=Inf,  True if xiInf,  False

where Inf means not a number.

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.

Raises

TypeError – If x is not a Tensor.

Supported Platforms:

GPU

Examples

>>> is_inf = ops.IsInf()
>>> x = Tensor(np.array([np.log(-1), 1, np.log(0)]), mindspore.float32)
>>> output = is_inf(x)
>>> print(output)
[False False True]
