The torch.index_select( input,dim,index,out=None ) function returns a quantum set ... function to index the 1D tensor, 2D tensor and 3D tensor respectively.

torch.index_select¶ torch. index_select (input, dim, index, *, out = None) → Tensor ¶ Returns a new tensor which indexes the input tensor along dimension dim using the entries in index which is a LongTensor.. The returned tensor has the same number of dimensions as the original tensor (input).The dim th dimension has the same size as the length of index; other dimensions have …

torch.Tensor.select. Slices the self tensor along the selected dimension at the given index. This function returns a view of the original tensor with the given dimension removed. select () is equivalent to slicing. For example, tensor.select (0, index) is equivalent to tensor [index] and tensor.select (2, index) is equivalent to tensor [:,:,index].

05.04.2017 · What is the major difference between gather and index_select, other than that gather “gathers” values and index_select “selects” values? Is there any difference on the basis of underlying storage? Also, if I want to assign a sub-tensor of a tensor (indexed using index_select) to a new value? How do I do that? For example, t = torch.Tensor([[1,2,5],[3,4,6]]) t1 = …
