torch.sqrt# 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}} outi=inputi 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])
