- sign(x)[source]¶
Element-wise sign.
Returns an indication of the sign of a number for each element \(x_i\) of the input tensor \(x\).
- Parameters
inp – input tensor. Should have a numeric data type.
- Returns
a tensor containing the evaluated result for each element in \(x\). The returned array must have the same data type as \(x\).
Examples
Element-wise sign:
>>> x = Tensor([1, -1, 0]) >>> F.sign(x) Tensor([ 1 -1 0], dtype=int32, device=xpux:0)
