mindspore.ops.csr_cos
- mindspore.ops.csr_cos(x: CSRTensor)[source]
Computes cosine of input element-wise.
\[out_i = \cos(x_i)\]Warning
Currently support data types float16 and float32. If use float64, there may be a problem of missing precision.
- Parameters
x (CSRTensor) – Input CSRTensor.
- Returns
CSRTensor, has the same shape and dtype as x.
- Raises
- Supported Platforms:
Ascend
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_cos(x) >>> print(output.values) [ 0.5403023 -0.41614684]
