mindspore.ops.csr_acosh(x: CSRTensor)[source]

Computes inverse hyperbolic cosine of the inputs element-wise.

\[out_i = \cosh^{-1}(input_i)\]
Parameters

x (CSRTensor) – The input CSRTensor of inverse hyperbolic cosine function, its element must be in range [1, inf].

Returns

CSRTensor, has the same shape and type as x.

Raises

TypeError – If x is not a CSRTensor.

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