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 = …

torch.Tensor.select — PyTorch 1.10.1 documentation
https://pytorch.org/docs/stable/generated/torch.Tensor.select.html
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].
