mindspore.ops.csr_isinf
- mindspore.ops.csr_isinf(x: CSRTensor)[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 not a number.
- Parameters
x (CSRTensor) – The input CSRTensor.
- Returns
CSRTensor, has the same shape of input, and the dtype is bool.
- Raises
TypeError – If x is not a CSRTensor.
- Supported Platforms:
GPU
CPU
Examples
>>> from mindspore import dtype as mstype >>> from mindspore import Tensor, ops, CSRTensor >>> indptr = Tensor([0, 1, 2, 2], dtype=mstype.int32) >>> indices = Tensor([3, 0], dtype=mstype.int32) >>> values = Tensor([-1, 2], dtype=mstype.float32) >>> shape = (3, 4) >>> x = CSRTensor(indptr, indices, values, shape) >>> output = ops.csr_isinf(x) >>> print(output.values) [False False]
