How to tile a tensor?

If I have a tensor like: z = torch.FloatTensor([[1,2,3],[4,5,6]]) 1 2 3 4 5 6 How might I turn it into a tensor like: 1 2 3 1 2 3 1 2 3 1 2 3 4 5 6 4 5 6 4 5 6 4 5 6 I imagine that torch.repeat() is somehow in play here. The only solution I have come up with is to do: z.repeat(1,4).view(-1, 3) Is there one operation that collapses these two commands into one? Moreover, if I have columnwise data I want to repeat, how can I do this without transposing the data back and forth? For example,…

As mentioned here How to tile a tensor? - #2 by richard, we can build wit .repeat() and .view(). For your solution: a.view(-1, 1).repeat(1,2).view(2,4).repeat(1,2).view(4,4)
