mindspore.Tensor.isfinite

Tensor.isfinite() → Tensor

Determine which elements are finite for each position. If elements are not NaN , -INF , INF, they are finite.

$$\begin{array}{r}ou{t}_i=\{\begin{array}{ll}& \text{ if }{x}_i=\text{Finite},True\\ & \text{ if }{x}_i\ne \text{Finite},False\end{array}\end{array}$$

Returns

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

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
