Hi guys, I am looking for a method to index customized contiguous rows of 2d tensor with even/odd starting point. For example, mat is a 4*4 2d tensor. I know a[1::2,:] and a[::2,:] can index odd/even rows.
But I dont know how to index 2 contiguous rows starting from odd rows (i.e., 1 and 3) for getting rows 1/2 and 3/4, respectively. Any idea? Thanks.
