mindspore.ops.csr_acos
- mindspore.ops.csr_acos(x: CSRTensor)[source]
Computes arccosine of input csr_tensors element-wise.
\[out_i = \cos^{-1}(x_i)\]- Parameters
x (CSRTensor) – Input CSRTensor.
- Returns
CSRTensor, has the same shape and dtype as x.
- Raises
complex128.

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_acos(x) >>> print(output.values) [3.1415927 nan]
