In CaSuDa and Gibbs solver, it returns all_I, all_m and E.
(the order may be inverted).
Worth checking if this breaks annealing.execute

The sign convention may differ from the existing solvers. Can you check?

ok, I just realise that the Gibbs solver itself is probably not compatible with Torch. Let me open follow-up

The image classification uses p-kit in an elegant way, not just use p-kit in some way! The algorithm uses a PCircuit more than other implementations I tried. It does not give currently the best results compared to some other experiments I did, but it is the right direction and there is space for optimization. The new primitives and solver (used in this image classification demo) can be used by other algorithms and other users/researchers. Calculation speed has been optimized as the first version was impossibly slow. Also note that the training is very fast, but then the inference is slow.
