        Computes inverse hyperbolic cosine of the inputs element-wise.

        .. math::

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

        .. warning::
            Given an input tensor input, the function computes inverse hyperbolic cosine of every element.
            Input range is [1, inf].

        Args:
            input (Tensor): The input tensor of inverse hyperbolic cosine function.

        Returns:
            Tensor, has the same shape and type as `input`.

        Raises:
            TypeError: If `input` is not a Tensor.

        Supported Platforms:
            ``Ascend`` ``GPU`` ``CPU``

        Examples:
            >>> import mindspore
            >>> import numpy as np
            >>> from mindspore import Tensor, ops
            >>> input = Tensor(np.array([1.0, 1.5, 3.0, 100.0]), mindspore.float32)
            >>> output = ops.acosh(input)
            >>> print(output)
