mindspore.ops.isnan
- mindspore.ops.isnan(x)[source]
Determines which elements are NaN for each position.
\[\begin{split}out_i = \begin{cases} & \ True,\ \text{ if } x_{i} = \text{Nan} \\ & \ False,\ \text{ if } x_{i} \ne \text{Nan} \end{cases}\end{split}\]where \(Nan\) means not a number.
- Parameters
x (Tensor) – The input tensor. \((N,*)\) where \(*\) means, any number of additional dimensions.
- 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
>>> x = Tensor(np.array([np.log(-1), 1, np.log(0)]), mindspore.float32) >>> output = ops.isnan(x) >>> print(output) [ True False False]
