How do I stack copies of a 1D tensor in keras? I have a tensor x of shape (5, 1). I would like to stack 10 copies of it so that I get a tensor of shape (5, 10). In a sort, it would look like [x|..|x]. How to do it the keras way? I have tried the Concatenate layer, but I got an error.
Help is welcome!
After many troubles with Concatenate, I simply did:
x = Reshape((5, 1))(x)
t = ones((1, 10))
stacked_x = x @ t

Maths help a lot. Should have thought about it earlier.
