How do you transpose a tensor in LibTorch?

Question

I can't seem to figure out how to transpose a tensor in LibTorch, the (C++ version of PyTorch).

torch::Tensor one_T = torch::rand({6, 6});

int main() {
    std::cout << one_T.transpose << "\n";
}

My error...

Answer 1

one_T.transpose(0, 1)

The 0, 1 is the type of default transpose used in PyTorch and Numpy without being specified.
