This PR adds support for training and predicting Born Effective Charges (BEC) as a 4th quantity. * Adds corresponding `BORN_EFFECTIVE_CHARGES` keys to `_keys.py` and constants to `_const.py`. * Modifies `sevenn/train/dataload.py` to correctly parse and extract BEC per atom. * Extends `build_E3_equivariant_model` in `sevenn/model_build.py` to add an `IrrepsLinear` layer mappings hidden features to a 9x0e irrep if `is_train_bec` is enabled. * Adds a `BECLoss` class in `sevenn/train/loss.py` to compare true BEC vs predicted BEC tensors. * Updates `SevenNetCalculator` to properly expose `born_effective_charges` in results.

Shorten lines to fix E501 errors related to line length exceeding 85 characters in `sevenn/calculator.py`, `sevenn/train/dataload.py` and `tests/unit_tests/test_data.py`. Co-authored-by: AugustinLu <59640670+AugustinLu@users.noreply.github.com>
* Added `BornEffectiveCharges` missing configuration key in `sevenn/error_recorder.py` to enable tracking metrics (like RMSE). * Adjusted `predict_bec` in `sevenn/model_build.py` to ensure correct dimensionality matching after node features reduction depending on `READOUT_AS_FCN` configuration. * Added `test_bec_training.py` demonstrating the correct working of the pipeline.

Fixes line length errors causing E501 errors in `sevenn/model_build.py` and fixes the `test_bec_training.py` formatting errors and missing imports to comply with isort and flake8 specifications. Co-authored-by: AugustinLu <59640670+AugustinLu@users.noreply.github.com>
Fixed isort complaining that `import time` should be placed before `from copy import deepcopy` in `test_bec_training.py`. Co-authored-by: AugustinLu <59640670+AugustinLu@users.noreply.github.com>
* Fix `sevenn/error_recorder.py` to index `y_ref` and `y_pred` with proper dimension handling. `~unlabelled_idx` is mapped correctly depending on `y_ref.dim()`. * Ensure `sevenn/calculator.py` properly reshapes output `PRED_BORN_EFFECTIVE_CHARGES` `(N, 9)` to `(N, 3, 3)`.

Resolves a flake8 (E501) error occurring on line 152. Co-authored-by: AugustinLu <59640670+AugustinLu@users.noreply.github.com>
Updates `test_bec_training.py` to: - Compute and print overall RMSE for Born Effective Charges. - Compute and print per-component (3x3) RMSE. - Generate and save a 3x3 parity plot grid (`bec_parity_plot.png`) for manual verification. Co-authored-by: AugustinLu <59640670+AugustinLu@users.noreply.github.com>
This fixes a `seed-isort-config` failure during pre-commit hooks triggered by importing `matplotlib.pyplot` in the newly added `test_bec_training.py` script. Co-authored-by: AugustinLu <59640670+AugustinLu@users.noreply.github.com>
* Adjusted `test_bec_training.py` loading logic when collecting the true BEC values from test geometries. `extxyz` stores these arrays in `calc.results['born_effective_charges']` instead of `.arrays` since it interprets these fields as output from calculators via the `Properties` format standard string. Co-authored-by: AugustinLu <59640670+AugustinLu@users.noreply.github.com>
* Deletes the leftover ad-hoc test scripts `test_ase.py`, `test_ase2.py`, and mock `xyz`/`pth` artifacts created during verification of `ase.io.extxyz`. These files were triggering formatting violations with the pre-commit system. Co-authored-by: AugustinLu <59640670+AugustinLu@users.noreply.github.com>
- Add `born_effective_charges` prediction head using `CartesianTensor` and e3nn Irreps representation of rank-2 tensors. - Parse BEC data in `sevenn/train/dataload.py` and convert from true Cartesian 3x3 to target irreps format in loss preprocess. - Update `SevenNetCalculator` to map BEC irreps back to Cartesian tensor format. - Added a script `test_bec_training.py` demonstrating model execution and evaluation.

- Added `born_effective_charges` parsing from extxyz data. - Added BEC target (3x3 tensor) mapped to Irreps `1x0e+1x1e+1x2e`. - Adjusted final layer `lmax=2` and `parity_mode='full'` when `IS_TRAIN_BEC` is enabled to support off-diagonal tensor components. - Added `BECLoss` mapping Cartesian truth back to Irreps for correct gradient calculation. - Optimized `CartesianTensor` instantiation with class-level caching to fix O(N) memory leaks and `copy.deepcopy` failures in tests. - Added `born_effective_charges` to SevenNetCalculator results. Co-authored-by: AugustinLu <59640670+AugustinLu@users.noreply.github.com>
- Updated `sevenn/train/graph_dataset.py` `_run_stat` to natively collect and calculate dataset statistics (min, max, mean, std, median) for `KEY.BORN_EFFECTIVE_CHARGES` arrays. - Added safe skipping logic (`if len(dct['_array']) == 0: continue`) when a property is missing to maintain backward compatibility with datasets that only contain energy and forces. Co-authored-by: AugustinLu <59640670+AugustinLu@users.noreply.github.com>
- Refactored `_get_cartesian_tensor` in `BECLoss`, `ErrorRecorder`, and `SevenNetCalculator` to properly cache both `CartesianTensor('ij')` and its associated `reduced_tensor_products()` (`rtp`) at the instance level (`self._ct`, `self._rtp`).
- This fixes an `AttributeError`/`TypeError` caused by mismatched return unpacking and completely eliminates the severe `O(N)` time inflation/memory leak caused by `e3nn` dynamically compiling `fx.GraphModule`s on every training batch.
- Removed all temporary patch/testing scripts from the repository root.
- Ensured code formatting passes Flake8 and Isort CI hooks.

- Verified no additional source code changes are required for tensor target error recording discrepancies. - The `error_recorder` natively supports `ComponentRMSE` and `MAE` for evaluating element-wise metrics (like what is used in external parity plots). The default `RMSE` evaluates $L_2$ vector sums, making it naturally $\approx 3\times$ larger for 9-component (vdim=9) matrices.

- Deleted `debug_cart.py`, `test_rmse.py`, `test_rmse_live.py`, and `test_rmse_math.py` which were accidentally left in the repository root during the previous commit. - These unformatted temporary files were failing the `prek` (`isort` and `flake8`) GitHub Actions CI pipeline checks. - Verified that `setup.cfg` does not contain `matplotlib` in `known_third_party`. Co-authored-by: AugustinLu <59640670+AugustinLu@users.noreply.github.com>
- Add `mae`: `nn.L1Loss` to `loss_dict` in `sevenn/train/optim.py` to allow training on MAE instead of MSE. Co-authored-by: AugustinLu <59640670+AugustinLu@users.noreply.github.com>

- Removed `test_cart.py`, `test_mae.py`, `debug_ase_read.py`, and other temporary scratchpad files from the root directory to fix `prek` (pre-commit) GitHub CI validation failures for `flake8` and `isort`. Co-authored-by: AugustinLu <59640670+AugustinLu@users.noreply.github.com>

- Added `mae`: `nn.L1Loss` to `loss_dict` in `sevenn/train/optim.py`. - Reverts previous destructing commit and ensures the codebase is completely clean of temporary scratchpad files to pass `flake8` and `isort` CI tests in `prek`. Co-authored-by: AugustinLu <59640670+AugustinLu@users.noreply.github.com>
- Deletes the 400KB `dummy_ckpt.pth` test artifact from the root repository as per the PR code review feedback. - Final validation of L1Loss implementation inside `sevenn/train/optim.py`. Co-authored-by: AugustinLu <59640670+AugustinLu@users.noreply.github.com>
