torch.log2# torch.log2(input: Tensor, *, out: Optional[Tensor]) → Tensor# Returns a new tensor with the logarithm to the base 2 of the elements of input. yi=log2(xi)y_{i} = \log_{2} (x_{i}) yi=log2(xi) Parameters input (Tensor) – the input tensor. Keyword Arguments out (Tensor, optional) – the output tensor. Example: >>> a = torch.rand(5) >>> a tensor([ 0.8419, 0.8003, 0.9971, 0.5287, 0.0490]) >>> torch.log2(a) tensor([-0.2483, -0.3213, -0.0042, -0.9196, -4.3504])
