torch.atanh¶
- torch.atanh(input, *, out=None) Tensor ¶
Returns a new tensor with the inverse hyperbolic tangent of the elements of
input
.Note
The domain of the inverse hyperbolic tangent is (-1, 1) and values outside this range will be mapped to
NaN
, except for the values 1 and -1 for which the output is mapped to +/-INF respectively.- Parameters
input (Tensor) – the input tensor.
- Keyword Arguments
out (Tensor, optional) – the output tensor.
Example:
>>> a = torch.randn(4).uniform_(-1, 1) >>> a tensor([ -0.9385, 0.2968, -0.8591, -0.1871 ]) >>> torch.atanh(a) tensor([ -1.7253, 0.3060, -1.2899, -0.1893 ])
