torch.sqrt — PyTorch 2.7 documentation (original) (raw)

Shortcuts

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

Returns a new tensor with the square-root of the elements of input.

outi=inputi\text{out}_{i} = \sqrt{\text{input}_{i}}

Parameters

input (Tensor) – the input tensor.

Keyword Arguments

out (Tensor, optional) – the output tensor.

Example:

a = torch.randn(4) a tensor([-2.0755, 1.0226, 0.0831, 0.4806]) torch.sqrt(a) tensor([ nan, 1.0112, 0.2883, 0.6933])
