Here is the question:
suppose:
tensor a is a 3x3 tensor
tensor b is a 4x3 tensor
tensor c is a 5x3 tensor
I want to build a tensor which contains all the unique row tensor of these three tensors
example:
a = [[1,2,3],[4,5,6],[7,8,9]]
b = [[1,3,7],[2,4,8],[3,7,9],[4,5,6]]
c = [[1,2,3],[2,4,8],[3,7,9],[3,5,6],[7,8,9]]
I expect the ouput is a 3xn tensor, which in this example should be:
[[1,2,3],[4,5,6],[7,8,9],[1,3,7],[2,4,8],[3,7,9],[3,5,6]]
Someone could help? Thank you in advance
