Rewrote the code to use the torch batch SVD. The code still assumes that the input and output must be numpy arrays, so they are converted to torch tensors and then back to numpy arrays.

I have changed the get_2d_proejction( ) function. The original one was written in numpy. This commit makes use of the pytorch batch SVD.
Since the inputs and outputs are supposed to be numpy arrays, I change them to tensor at the start and then back to arrays at the end.
