5a02f72f - Modified batched residuals return of torch.linalg.lstsq (#54722)

Modified batched residuals return of torch.linalg.lstsq (#54722) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/54722 SciPy and NumPy operate only on non-batched input and return an empty array with shape (0,) if rank(a) != n. The behavior for non-batched inputs is NumPy and SciPy compatible and the same result is computed. For batched inputs, if any matrix in the batch has a rank less than `n`, then an empty tensor is returned.
