mindspore.Tensor.isfinite

Tensor.isfinite(input) → Tensor

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.

Supported Platforms:

Ascend GPU CPU

Examples

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