mindspore.ops.csr_isnan
- mindspore.ops.csr_isnan(x: CSRTensor)[source]
Determines which elements are NaN for each position.
where
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:

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_isnan(x) >>> print(output.values) [False False]
