                Oh, in that case, neither of these solutions work: 
>>> t = torch.tensor([[1, 2, 3], [4, 4, 4]])                                                        
>>> t
tensor([[1, 2, 3],
        [4, 4, 4]])
>>> torch.cat(3*[t])
tensor([[1, 2, 3],
        [4, 4, 4],
        [1, 2, 3],
        [4, 4, 4],
     …
