Atanh
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.
$$ \mbox{out}_{i} = \tanh^{-1}(\mbox{input}_{i}) $$
atanh(input, *, out=None) -> Tensor
Returns a new tensor with the inverse hyperbolic tangent of the elements of input.
Examples

a = torch_randn(c(4))$uniform_(-1, 1)
