mindspore.ops.coo_isinf
- mindspore.ops.coo_isinf(x: COOTensor)[source]
Determines which elements are inf or -inf for each position.
\[\begin{split}out_i = \begin{cases} & \text{ if } x_{i} = \text{Inf},\ \ True \\ & \text{ if } x_{i} \ne \text{Inf},\ \ False \end{cases}\end{split}\]where \(Inf\) means infinitity or negative infinitity.
- Parameters
x (COOTensor) – The input COOTensor.
- Returns
COOTensor, has the same shape of input, and the dtype is bool.
- Raises
TypeError – If x is not a COOTensor.
- Supported Platforms:
GPU
CPU
Examples
>>> from mindspore import dtype as mstype >>> from mindspore import Tensor, ops, COOTensor >>> indices = Tensor([[0, 1], [1, 2]], dtype=mstype.int64) >>> values = Tensor([-1, 2], dtype=mstype.float32) >>> shape = (3, 4) >>> x = COOTensor(indices, values, shape) >>> output = ops.coo_isinf(x) >>> print(output.values) [False False]
