torch.tanh(input, *, out=None) → Tensor¶

Returns a new tensor with the hyperbolic tangent of the elements of input.

outi=tanh⁡(inputi)\text{out}_{i} = \tanh(\text{input}_{i})

Parameters

input (Tensor) – the input tensor.

Keyword Arguments

out (Tensor, optional) – the output tensor.

Example:

a = torch.randn(4) a tensor([ 0.8986, -0.7279, 1.1745, 0.2611]) torch.tanh(a) tensor([ 0.7156, -0.6218, 0.8257, 0.2553])
