introduction to pytorch the stack operation allows you to construct tensor by stacking list of tensors along dimension the resultant tensor will have its dimension increased by one listing - shows how the stacking operation operates along each dimension note that the stack operation takes two parametersthe list of tensors and the stacking dimension the range of dimension is equal to the range of the tensors to be stacked listing - stacking tensors in [ ] torch zeros( , in [ ] out[ ]tensor([[ ][ ]]in [ ] shape out[ ]torch size([ ]in [ ] torch stack([ , , ] in [ ] out[ ]tensor([[[ ][ ]][[ ][ ]][[ ][ ]]]in [ ] shape out[ ]torch size([ ]in [ ] torch stack([ , , ]
