`e3nn` is declared only in the `dpa-adapt` extra, but
`sezm_nn/projection.py` imported it at module scope. That module is reached
from `deepmd/pt/model/descriptor/__init__.py`, so on an installation without
that extra `import deepmd.pt.model.model` raised
ModuleNotFoundError: No module named 'e3nn'
and the whole PyTorch backend was unusable, whether or not the user went
anywhere near a SeZM descriptor. `pip check` stays clean, because nothing
declares the dependency that the import actually creates.
Import `e3nn.o3` inside the two projection builders that need it instead, and
raise an ImportError naming the package and the extra when it is missing.
Both builders need it: the e3nn grid backend uses `ToS2Grid`/`FromS2Grid`,
and the Lebedev backend uses `spherical_harmonics`, so switching
`grid_method` is not a way to avoid the dependency and the message does not
suggest it.
Import timing and the error text are the only changes; no default, no
numerical behaviour and no public API is touched.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Only translate a missing e3nn module error.
This handler catches import failures raised inside an installed e3nn package or one of its dependencies. It then reports that e3nn is not installed. Preserve those failures so users can diagnose the actual broken dependency. Catch ModuleNotFoundError only when it identifies e3nn.

Reviewed the complete current diff and existing discussion at this head. The lazy import fixes the unconditional PyTorch-backend dependency as intended. The existing unresolved inline finding is valid and I am not duplicating it: catching every ImportError can misreport an installed e3nn whose import fails because of a broken/transitive dependency as “e3nn is not installed”; the handler should only translate the missing-e3nn case and re-raise other import failures unchanged.
Disposition: COMMENT / NEEDS HUMAN REVIEW for now because the exact-head Test Python and Test C++ workflows are still in progress. The completed CUDA, C++ build, C-library build, package/PyPI, and CodeQL workflows are green.

Re-reviewed because the exact-head CI state has materially changed since the prior monitoring pass. All GitHub Actions workflows for this head are now completed successfully, so CI is no longer the reason to defer a final disposition.
The existing unresolved inline finding remains a concrete correctness/diagnostic blocker: _import_e3nn_o3() catches every ImportError, so an installed e3nn whose own import fails because of a broken/transitive dependency is incorrectly reported as “e3nn is not installed.” Please translate only the ModuleNotFoundError corresponding to the missing e3nn package and re-raise other import failures unchanged. I am not duplicating the already-precise inline comment.

e3nnis declared only in thedpa-adaptoptional extra, butdeepmd/pt/model/descriptor/sezm_nn/projection.pyimported it at module scope. That module isreached unconditionally from
deepmd/pt/model/descriptor/__init__.py, so on an installation withoutthat extra:
The whole PyTorch backend was therefore unusable, whether or not the user went anywhere near a SeZM
descriptor.
pip checkstays clean, because nothing declares the dependency that the import actuallycreates — the failure only shows up at import time, and the traceback points at a grid-projection
helper rather than at a missing extra.
Change
Import
e3nn.o3inside the two projection builders that need it, and raise anImportErrornamingboth the package and the extra when it is absent.
Both builders need it, so switching grid backends is not a way to avoid the dependency and the message
does not suggest it:
_build_e3nn_projection_matsToS2Grid,FromS2Grid_build_lebedev_projection_matsspherical_harmonicsImport timing and the error text are the only changes. No default, no numerical behaviour and no
public API is touched.
Tests
source/tests/pt/test_optional_e3nn_import.pyblockse3nnwith a meta-path hook in a subprocess(already-imported modules cannot be un-imported in-process) and checks that
deepmd.pt.model.modelanddeepmd.pt.entrypoints.mainboth import, and that building a projectorwithout
e3nnreports the package and the extra.Without the fix all three fail; with it all three pass.
test_descriptor_sezm_grid_projection.pystill passes (21 tests, 179 subtests), so the e3nn path itself is unaffected.
