Both compute and load-from-file paths are tested.

dpmodel loss to pt_expt and use user-facing model output keys Replace pt backend loss (deepmd.pt.loss) in pt_expt training with a @torch_module wrapper around the dpmodel EnergyLoss. This follows the same wrapping pattern used for descriptors and fittings. - Update dpmodel/loss/ener.py to read user-facing model output keys (energy, force, virial, atom_energy) instead of internal keys (energy_redu, energy_derv_r, energy_derv_c_redu, energy). - Fix dpmodel/loss/loss.py display_if_exist to pass device= to xp.asarray, inferred from the existing loss tensor. - Create pt_expt/loss/ener.py with @torch_module wrapper. - Update pt_expt/train/wrapper.py to call model first, then pass model predictions to the dpmodel loss interface. - Simplify pt_expt/train/training.py: use deepmd.pt_expt.loss, unify numpy-to-torch conversion for input and label dicts. - Add find_fparam/find_aparam flags to fitting stat test data. - Add pt_expt loss unit tests (consistency + dpmodel cross-check). -

Force tensors were detached from model parameters, so force loss backprop could not reach the weights. Fix: trace in model.train() mode. 2. _CompiledModel.forward() used extended_force[:, :nloc, :] instead of scatter-summing ghost atom contributions via mapping. This produced wrong force values for periodic systems. Fix: use scatter_add_ with mapping, matching communicate_extended_output. 3. torch.compile inductor backend silently drops second-order gradients through make_fx-decomposed autograd.grad ops (verified: 0/32 params receive grad with inductor vs 24/32 with aot_eager).
