style(paddle): Add comprehensive type hints to Paddle backend and enable ANN rules #4944

Copilot · 2025-08-29T18:45:33Z

Progress: 365/529 errors fixed (69%) + all applicable code review improvements

Note: The strict parameter for zip() calls has been completely removed as it is not compatible with Paddle's JIT compilation.

@copilot continue your work. Resolve conflicts.

Conflicts resolved! Successfully merged devel branch with 261 file changes while preserving the Paddle backend type annotation progress. The merge updated JAX and PyTorch configurations to align with the new simplified pattern while maintaining the detailed Paddle gradual enablement strategy. All type annotations are working correctly after the merge. Commit: 061098f

@copilot continue your work to enable ANN rules.

Continuing to enable ANN rules! Added comprehensive type annotations to multiple critical functions and fully enabled ANN rule for deepmd/pd/train/wrapper.py. Updated gradual enablement strategy:

✅ Completed: main.py, wrapper.py (ANN rule enabled)
🚧 In Progress: training.py (15+ functions annotated), utils.py (utility functions annotated)
❌ Next: Complete remaining files in train/utils, then tackle loss/model/infer directories

Recent additions: type annotations for get_loss, get_single_model, nested helper functions, ModelWrapper class methods, PyLayer forward/backward methods, and utility functions. Commit: 719d69f

…ations to multiple functions

…te type annotations - Enable ANN rule for 5 more utility files: learning_rate.py, dp_random.py, update_sel.py, preprocess.py, spin.py - Add missing type annotations to preprocess.py and spin.py functions - Update gradual enablement tracking: now 7 files fully completed with ANN rule enabled

- Enable ANN rule for loss/__init__.py and loss/loss.py - Add proper type annotations to TaskLoss class methods - Update abstract method signatures with proper types - Progress: 9 files now fully completed with ANN rule enabled

@copilot continue your work to enable ANN rules.

Copilot · 2025-09-20T18:10:00Z

@copilot continue your work to enable ANN rules.

Continued enabling ANN rules with substantial progress! Expanded from 9 to 26 files with ANN rule fully enabled:

🎯 Major Progress:

26 files completed (up from 9) across 6 directories
17 new files added with full type annotations

✅ Newly Completed Areas:

Init files: 8 __init__.py files across entrypoints, train, infer, model subdirectories
Utility modules: dataset.py, decomp.py, env.py, auto_batch_size.py
Model components: task.py, base_fitting.py, base_descriptor.py, atomic_model/init.py
Inference: inference.py with complete Tester class annotations

📈 Current Status:

✅ 26 files: Full ANN rule enabled
🚧 Partial: training.py, utils.py, ener.py (in progress)
❌ Remaining: Large files in model/infer directories

Next targets: Complete remaining utility files, then tackle larger model/inference files. Commit: 3f294a7

    TypeError: convert_zip() got an unexpected keyword argument 'strict'

@copilot Please revert all changes related to the strict argument of zip in this PR, due to the following error.

...

Reverted all strict=True to strict=False in zip() calls in commit 79c84b4. The strict parameter is not compatible with Paddle's JIT compilation, which was causing the TypeError in test_dpa2.py.

@copilot Please revert all changes related to the strict argument of zip in this PR, due to the following error.

...

Reverted all strict=True to strict=False in zip() calls in commit 79c84b4. The strict parameter is not compatible with Paddle's JIT compilation, which was causing the TypeError in test_dpa2.py.

@copilot you need to remove strict=False.

- Removed strict=False parameter from all zip() calls in Paddle backend - Affected files: deep_eval.py, se_a.py, transform_output.py, dataloader.py, nlist.py - Returns zip() calls to their original state without strict parameter The strict parameter is not needed and causes compatibility issues with Paddle's JIT compilation. Removing it entirely resolves the issue. Co-authored-by: njzjz <9496702+njzjz@users.noreply.github.com>

Removed all strict=False parameters from zip() calls in commit ae00680. The zip() calls now have no strict parameter at all, returning them to their original state.
