mindspore.ops.isinf
- mindspore.ops.isinf(input)[source]
Determines which elements are inf or -inf for each position.
\[\begin{split}out_i = \begin{cases} & \ True,\ \text{ if } x_{i} = \text{Inf} \\ & \ False,\ \text{ if } x_{i} \ne \text{Inf} \end{cases}\end{split}\]where \(Inf\) means not a number.
- Parameters
input (Tensor) – The input tensor.
- Returns
Tensor, has the same shape of input, and the dtype is bool.
- Raises
TypeError – If input is not a Tensor.
- Supported Platforms:
Ascend
GPU
CPU
Examples
>>> import mindspore >>> import numpy as np >>> from mindspore import Tensor, ops >>> x = Tensor(np.array([np.log(-1), 1, np.log(0)]), mindspore.float32) >>> output = ops.isinf(x) >>> print(output) [False False True] >>> x = Tensor(2.1, mindspore.float64) >>> output = ops.isinf(x) >>> print(output) False
