torch_sign(self)

Arguments

self

(Tensor) the input tensor.

sign(input, out=NULL) -> Tensor

Returns a new tensor with the signs of the elements of input.

$${\text{out}}_i=\text{sgn}({\text{input}}_i)$$

Examples

if (torch_is_installed()) {

a = torch_tensor(c(0.7, -1.2, 0., 2.3))
a
torch_sign(a)
