torch.tanh

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

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

$$\text{out}_{i} = \tanh(\text{input}_{i})$$

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])
