mindspore.ops.IsFinite

class mindspore.ops.IsFinite[源代码]

Determines which elements are finite for each position.

\[\begin{split}out_i = \begin{cases} & \text{ if } x_{i} = \text{Finite},\ \ True\ \\ & \text{ if } x_{i} \ne \text{Finite},\ \ False \end{cases}\end{split}\]
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:

Ascend GPU CPU

Examples

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