📝 Walkthrough

"""

Walkthrough

The CINN JIT compilation logic for Paddle models is moved from the run() method to the __init__ method of the Trainer class, ensuring static compilation occurs during initialization. Additionally, new informational log messages about CINN compilation status are added to the C++ inference code after model loading.

Changes

File(s) Change Summary
deepmd/pd/train/training.py CINN JIT compilation moved from run() to __init__ of Trainer; ensures pre-DDP compilation.
source/api_cc/src/DeepPotPD.cc Added log messages after model loading to indicate CINN compilation status.

🧹 Nitpick comments (5)
deepmd/pd/train/training.py (5)

609-609: Remove redundant backend assignment.

The line backend = "CINN" if CINN else None is redundant since this code block only executes when CINN is True. The backend will always be "CINN".

Apply this diff to simplify the code:

-            backend = "CINN" if CINN else None
+            backend = "CINN"

631-635: Clean up commented code.

The commented lines should either be removed if they're no longer needed, or properly documented if they represent future functionality.

Consider removing these commented lines or adding a TODO comment explaining their purpose:

                    },  # label,
-                    # None, # task_key
-                    # False, # inference_only
-                    # False, # do_atomic_virial
-                    # None, # fparam
-                    # None, # aparam
                ],

641-643: Fix typo in log message.

There's a typo: "traning" should be "training".

Apply this diff to fix the typo:

            log.info(
                "Enable CINN during training, there may be some additional "
-                "compilation time in the first traning step."
+                "compilation time in the first training step."
            )

610-638: Consider validating input specification compatibility.

The input_spec definition is quite detailed and hard-coded. Consider adding validation to ensure that the actual runtime inputs match this specification, as mismatches could cause compilation errors.

The current implementation assumes specific tensor shapes and types. If the actual model inputs differ from this specification, CINN compilation might fail. Consider adding runtime validation or making the input specification more flexible based on the actual model requirements.


604-607: Consider moving imports to module level.

While the conditional imports work correctly, consider moving the paddle imports to the module level for better performance if CINN checking happens frequently.

The current approach:

if CINN:
    from paddle import (
        jit,
        static,
    )

Could be optimized to:

# At module level
try:
    from paddle import jit, static
    PADDLE_JIT_AVAILABLE = True
except ImportError:
    PADDLE_JIT_AVAILABLE = False

# In the conditional block
if CINN and PADDLE_JIT_AVAILABLE:
    # Use jit and static

602-603: LGTM on the wrapper ordering comment.

The comment correctly explains the important sequencing requirement for CINN compilation before distributed wrappers.
