The torch.acos ()
function provides support for the inverse cosine function in PyTorch. The input is assumed to be in the range [-1, 1] and outputs the output in radians. Returns nan, if the input is not in the range [-1, 1]. Input type — tensor, and if the input contains more than one element, the inverse cosine is calculated for each element.
Syntax : torch.acos (x, out = None)
Parameters :
x : Input tensor
name (optional): Output tensorReturn type : A tensor with the same type as that of x.
