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

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

out=−1×input\text{out} = -1 \times \text{input}

Parameters

input (Tensor) – the input tensor.

Keyword Arguments

out (Tensor, optional) – the output tensor.

Example:

a = torch.randn(5) a tensor([ 0.0090, -0.2262, -0.0682, -0.2866, 0.3940]) torch.neg(a) tensor([-0.0090, 0.2262, 0.0682, 0.2866, -0.3940])
