torch.cosh
torch.cosh(input, *, out=None) -> Tensor
Returns a new tensor with the hyperbolic cosine  of the elements of
   "input".
  \text{out}_{i} = \cosh(\text{input}_{i})

Parameters:
      input (Tensor) -- the input tensor.
Keyword Arguments:
      out (Tensor, optional) -- the output tensor.
Example:
  >>> a = torch.randn(4)
  >>> a
  tensor([ 0.1632,  1.1835, -0.6979, -0.7325])
  >>> torch.cosh(a)
  tensor([ 1.0133,  1.7860,  1.2536,  1.2805])

Note:
 When "input" is on the CPU, the implementation of torch.cosh may
 use the Sleef library, which rounds very large results to
 infinity or negative infinity. See here for details.
