WebAug 5, 2024 · 1 torch.gather (input=input,dim= 0,index=indx) torch.gather () creates a new tensor from the input tensor by taking the values from each row or column along the input dimension. The index values are passed as tensors, specifying which value to take from each ‘row’ or ‘column’. Webtorch.gather(input, dim, index, *, sparse_grad=False, out=None) → Tensor. Gathers values along an axis specified by dim. For a 3-D tensor the output is specified by: out[i] [j] [k] = input[index[i] [j] [k]] [j] [k] # if dim == 0 out[i] [j] [k] = input[i] [index[i] [j] [k]] [k] # if dim == 1 … Note.
