I have this tensor:
tensor([[425.0000, 625.0000],
        [550.0000, 566.6667],
        [700.0000, 600.0000]])

and I want to obtain something like this:
tensor([[425.0000, 425.0000, 625.0000, 625.0000],
        [550.0000, 550.0000, 566.6667, 566.6667],
        [700.0000, 700.0000, 600.0000, 600.0000]

Is there anyway to do this efficiently?
