RuntimeError: The size of tensor a (378) must match the size of tensor b (281) at non-singleton dimension 2

When I train the model,it said ' normD_down = D_down + norm_down RuntimeError: The size of tensor a (378) must match the size of tensor b (281) at non-singleton dimension 2',I don't know how to solve it. Could you tell me where I need to pay attention to of somewhere else I made errors.Thanks!
