mindspore.ops.csr_isfinite

mindspore.ops.csr_isfinite(x: CSRTensor)[source]

Determines which elements are finite for each position.

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

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:: Ascend GPU CPU

Examples

>>> 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_isfinite(x)
>>> print(output.values)
