- mindspore.mint.isfinite(x)[source]
Determine which elements are finite for each position. If elements are not
NaN
,-INF
,INF
, they are finite.\[\begin{split}out_i = \begin{cases} & \text{ if } x_{i} = \text{Finite},\ \ True \\ & \text{ if } x_{i} \ne \text{Finite},\ \ False \end{cases}\end{split}\]- Parameters
x (Tensor) – The input tensor.
- Returns
Tensor, has the same shape of input, and the dtype is bool.
- Raises
TypeError – If x is not a Tensor.

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