What is the simplest syntax to transform 2D tensor A B C D into A A B B A A B B C C D D C C D D Note they are parameter tensors, so I need autograd to back propagate gradient from latter into former. Thanks!

I found a numpy.repeat()-like function in latest pytorch (1.1), but it is needed to be called twice: z = x.repeat_interleave(2,dim=0).repeat_interleave(2,dim=1)

How to repeat a matrix into a bigger one along both dimensions?
