Torch Gather Vs Index_Select at Joseph Graves blog

Torch Gather Vs Index_Select. In summary, torch.gather can be seen as an extension of torch.index_select that enables independent indexing for each element. It doesn't modify the original tensor x. Returns a new tensor which indexes the input tensor along dimension dim using the entries in index which is a longtensor. Let’s demonstrate this with a 2d example, in which we select along dimension 1: If you specifically need to select entire rows or columns based on indices,. Gather (input, dim, index, *, sparse_grad = false, out = none) → tensor gathers values along an axis specified by dim. Torch.index_select returns a new tensor containing the selected elements. Torch.index_select selects elements along one dimension, while keeping the other ones unchanged. Keep all elements from all other dimensions, but pick elements in the target dimensions following the index tensor.
