chore: remove dead denoise code - #6018
Conversation
DenoiseLoss, DenoiseNet and TypePredictNet have been unreachable since they arrived with deepmodeling#3180: argcheck rejects loss.type="denoise", all three classes are abstract and cannot be instantiated, every denoise test has been skipped since deepmodeling#3190 (two days later), and coord_denoise_net is never assigned. Remove them together with the helpers they alone used (MaskLMHead, NonLinearHead) and the set_noise stubs, whose only caller path also cannot run. No behaviour change.

LmdbDataReaderis publicly re-exported fromdeepmd.dpmodel.utils, and its existingset_noiseno-op is removed here. That turns established calls intoAttributeError; retain a deprecated no-op compatibility method or explicitly treat this as a breaking API change.

set_noiseis a public method onLmdbDatasetand was explicitly covered bytest_set_noise_noop; removing it makes existing callers fail withAttributeError, even though the previous implementation was a no-op. Please retain a deprecated compatibility wrapper or document/version this as an intentional breaking API change rather than a no-behavior-change cleanup.

fitting is a required argument of DPAtomicModel and init_out_stat() dereferences it, so get_fitting_net() is never None. The else branches guarded by it rebuilt the updated_coord output that only DenoiseNet ever produced, in forward() and forward_lower() of ener/dipole/dos/polar/sezm (pt) and ener (pd). Drop the guards and unindent the live path. No behaviour change.

The Returns section still promised the raw forward_common_lower() result when no fitting net is present. That branch is gone, so state the outputs unconditionally.

The denoise cleanup itself is internally consistent on the current head, and the stale model-output branches noted in earlier reviews have been removed. One compatibility issue remains: LmdbDataReader is publicly re-exported from deepmd.dpmodel.utils, while this PR removes its existing set_noise() method outright. Even though the method is a no-op, this turns previously valid external calls into AttributeError. Please keep a deprecated no-op compatibility shim (ideally warning once / via the project’s deprecation mechanism) for at least a transition period. The same principle should be applied to any loader class considered public API.
Current checks show no failing CI on this head.

LmdbDataReader is re-exported in deepmd.dpmodel.utils.__all__, so deleting this method is an externally visible API break. Since the old behavior is a no-op, retaining a deprecated compatibility shim is very cheap and avoids turning existing calls into AttributeError.
DenoiseLoss,DenoiseNetandTypePredictNethave been unreachable since #3180:argcheckrejectsloss.type="denoise", so itsget_loss()branch is dead.fitting_net.coord_denoise_netis never assigned; theget_fitting_net() is not Noneguards feedingupdated_coorddie with it.Also drops the now-unused
MaskLMHeadandNonLinearHead.It is also an API removal:
LmdbDataReader.set_noise(exported fromdeepmd.dpmodel.utils) was a no-op, and bothDpLoaderSet.set_noisemethods always raisedAttributeError. No deprecation shim.#4644 (draft, conflicting) rewrites these files and will need a rebase.
