deepmd/jax/descriptor/base_descriptor.py (1)
2-7: Consider using absolute imports for better maintainability.While the current relative imports work, consider using absolute imports for improved maintainability and to avoid potential issues with circular imports in the future.
Here's a suggested change:
-from deepmd.dpmodel.descriptor.make_base_descriptor import ( +from deepmd.dpmodel.descriptor.make_base_descriptor import ( make_base_descriptor, ) -from deepmd.jax.env import ( +from deepmd.jax.env import ( jnp, )deepmd/jax/atomic_model/base_atomic_model.py (1)
11-18: LGTM: Well-implemented attribute processing function.The
base_atomic_model_set_attrfunction effectively processes attribute values based on their names. It handles special cases appropriately, including conversion to JAX arrays and creation of exclusion mask instances.Consider adding a docstring to improve the function's documentation. For example:
def base_atomic_model_set_attr(name: str, value: Any) -> Any: """ Process attribute values based on their names for atomic models. Args: name (str): The name of the attribute. value (Any): The value to be processed. Returns: Any: The processed value. """ # ... existing implementation ...This would enhance the function's self-documentation and make it easier for other developers to understand its purpose and usage.
deepmd/jax/model/ener_model.py (1)
21-24: LGTM:__setattr__implementation ensures consistent atomic model initialization.The method correctly handles the "atomic_model" attribute by serializing and deserializing it using
DPAtomicModel. This approach ensures consistency and proper initialization.Consider the performance impact of serializing and deserializing for large models. If performance becomes an issue, you might want to explore more efficient ways to ensure proper initialization without the full serialization cycle.
deepmd/jax/descriptor/se_e2_a.py (1)
Line range hint
25-38: LGTM: Custom setattr method with a minor suggestion.The custom
__setattr__method is well-implemented, providing type-specific processing for various attributes. It ensures JAX compatibility, handles complex data structures, and implements specific logic for different attributes.Consider adding a brief explanation for why "env_mat" doesn't store any value, as this might not be immediately clear to other developers.
deepmd/backend/jax.py (4)
35-40: LGTM. Consider adding a comment explaining the feature change.The addition of
Backend.Feature.IOto thefeaturesclass variable is appropriate. This change indicates that the JAX backend now supports I/O operations.Consider adding a brief comment explaining why this feature was added and the implications for the JAX backend's capabilities.
96-100: LGTM. Consider adding a docstring forserialize_from_file.The implementation of the
serialize_hookproperty usingserialize_from_filefromdeepmd.jax.utils.serializationis appropriate and consistent with the newly added I/O feature support.Consider adding a brief docstring for the
serialize_from_filefunction, explaining its purpose and any important details about its usage.
111-115: LGTM. Consider adding a docstring fordeserialize_to_file.The implementation of the
deserialize_hookproperty usingdeserialize_to_filefromdeepmd.jax.utils.serializationis appropriate and consistent with the newly added I/O feature support and theserialize_hookimplementation.Consider adding a brief docstring for the
deserialize_to_filefunction, explaining its purpose and any important details about its usage.
Line range hint
35-115: Overall implementation looks good. Consider adding more documentation.The changes to
JAXBackendsuccessfully implement I/O support for the JAX backend. The additions ofBackend.Feature.IOtofeatures,".jax"tosuffixes, and the implementation ofserialize_hookanddeserialize_hookproperties are consistent and well-structured.To improve code readability and maintainability:
- Add a comment explaining the addition of the I/O feature and its implications.
- Include brief docstrings for the imported
serialize_from_fileanddeserialize_to_filefunctions.- Consider adding a class-level docstring or updating the existing one to reflect the new I/O capabilities of the
JAXBackend.source/tests/consistent/io/test_io.py (1)
71-71: LGTM: Added JAX backend support in test_data_equalThe changes appropriately include JAX in the backend testing:
- Adding "jax" to the backend list ensures JAX models are tested alongside other backends.
- Including "jax_version" in the excluded keys maintains consistency in version-specific data handling across backends.
These additions improve the test coverage by including JAX support.
Consider adding a comment explaining why these specific keys are excluded from comparison, to improve code readability and maintainability.

deepmd/dpmodel/atomic_model/dp_atomic_model.py (2)
172-176: LGTM! Consider enhancing docstrings for clarity.The addition of
base_descriptor_clsandbase_fitting_clsas class attributes is a good approach to enhance the extensibility of theDPAtomicModelclass. This allows subclasses to override the base descriptor and fitting classes easily.Consider expanding the docstrings slightly to provide more context:
base_descriptor_cls = BaseDescriptor """The base descriptor class. Can be overridden by subclasses to use custom descriptors.""" base_fitting_cls = BaseFitting """The base fitting class. Can be overridden by subclasses to use custom fitting methods."""
184-185: LGTM! Consider a minor adjustment for consistency.The changes to use
cls.base_descriptor_clsandcls.base_fitting_clsin thedeserializemethod align well with the new class attributes. This modification enhances the flexibility of the deserialization process, allowing subclasses to control which descriptor and fitting classes are used.For consistency with the class attribute names, consider renaming the variables:
descriptor_obj = cls.base_descriptor_cls.deserialize(data.pop("descriptor")) fitting_obj = cls.base_fitting_cls.deserialize(data.pop("fitting"))to:
base_descriptor = cls.base_descriptor_cls.deserialize(data.pop("descriptor")) base_fitting = cls.base_fitting_cls.deserialize(data.pop("fitting"))This naming would more closely reflect their relationship to the class attributes.
deepmd/jax/atomic_model/dp_atomic_model.py (1)
22-22: Add a class docstring toDPAtomicModelThe class
DPAtomicModellacks a class-level docstring. Including a docstring will improve code readability and provide valuable context about the class's purpose and usage.deepmd/jax/model/model.py (2)
17-24: Enhance the docstring for better clarity and guidanceThe docstring for
get_standard_modelprovides a basic description but could be expanded for improved clarity. This enhancement would assist users in understanding the function's purpose and how to use it effectively.Consider including:
- A brief explanation of what a "standard model" is within the context of the project.
- Detailed descriptions of the expected structure and required keys in the
datadictionary.- Information about supported descriptor and fitting types.
- An example illustrating how to call the function with sample data.
48-55: Expand the docstring to provide comprehensive usage informationSimilarly, the docstring for
get_modelcould be made more informative. Providing additional details would help users navigate different model types and understand how to extend or customize models.Suggestions:
- Explain the purpose of the
get_modelfunction and how it differentiates between model types.- Outline the expected contents of the
datadictionary, including optional and required keys.- Describe how the
"type"key influences the model construction.- Provide examples for creating both standard and custom models.
source/tests/consistent/model/common.py (2)
9-11: Consider aliasingto_numpy_arrayto avoid confusionThe function
to_numpy_arrayis imported fromdeepmd.dpmodel.common. Since a similar function is imported from PyTorch and aliased astorch_to_numpy, consider aliasing this import for consistency and to prevent potential confusion.
75-87: Remove unused parameternatomsfromeval_jax_modelThe parameter
natomsineval_jax_modelis not used within the method. Consider removing it to simplify the function signature and avoid confusion.deepmd/dpmodel/model/transform_output.py (2)
36-36: Typo in comment: Correct 'brefore' to 'before'There is a typographical error in the comment. The word 'brefore' should be corrected to 'before'.
Apply this diff to fix the typo:
- # cast to energy prec brefore reduction + # cast to energy prec before reduction
Line range hint
27-36: Consider adding unit tests to validate array backend compatibilitySince the code now utilizes
array_api_compatto support different array backends, it would be beneficial to add unit tests that ensure correct functionality across the supported array libraries.deepmd/jax/fitting/fitting.py (1)
39-44: Add docstrings to fitting classes for improved clarityIncluding docstrings for
EnergyFittingNetandDOSFittingNetwill enhance code readability and provide valuable information about their purpose and usage to other developers.Also applies to: 47-52

pyproject.toml (3)
141-142: Summary of changes to pyproject.tomlThe modifications to
pyproject.tomlare focused on enhancing JAX support:
- Two new JAX-related dependencies added: 'orbax-checkpoint' and 'jax-ai-stack'.
- A new linting rule exception for the JAX-related code directory.
These changes are consistent with the existing structure and patterns in the file. They suggest a significant addition of JAX-related functionality to the project.
Please ensure that these changes are thoroughly tested and documented, especially considering their potential impact on the project's dependencies and coding standards.
Also applies to: 407-407
407-407: Verify the necessity of the new linting rule exception for JAX.A new path has been added to ignore the TID253 linting rule (banned module-level imports) for the JAX-related code:
"deepmd/jax/**" = ["TID253"]This is consistent with existing exceptions for other backend-specific directories (tf, pt). However, please confirm:
- Is this exception necessary for the JAX implementation?
- Have you considered alternatives to avoid module-level imports in the JAX code?
- Does this align with the project's coding standards and best practices?
To check for module-level imports in the JAX code that might trigger this rule, you can run:
#!/bin/bash # Search for module-level imports in the JAX-related code rg "^import\s+|^from\s+" deepmd/jaxIf possible, consider refactoring to avoid module-level imports, or document why they are necessary in this case.
141-142: Verify the necessity of new JAX-related dependencies.Two new dependencies have been added to the
jaxoptional dependencies:
- 'orbax-checkpoint'
- 'jax-ai-stack'
Both are conditional on Python version 3.10 or higher, which aligns with JAX requirements. However, please confirm:
- Are these dependencies essential for the new JAX-related features introduced in this PR?
- Have you tested the functionality with these new dependencies?
- Are there any specific version constraints needed for these packages?
To ensure these dependencies are used in the codebase, you can run the following command:
deepmd/jax/atomic_model/dp_atomic_model.py (1)
28-30:⚠️ Potential issueVerify that overriding
__setattr__does not interfere with Flax module behaviorOverriding
__setattr__in a class that inherits from a Flax module may affect parameter management, serialization, and other internal mechanisms of Flax. Ensure that this override is necessary and does not introduce unintended side effects on Flax's functionality.deepmd/jax/model/model.py (2)

86-97: Add documentation and type hints to improve code clarity.The
ArrayAPIVariableclass implementation looks correct but could benefit from improved documentation and type safety:
- Add a class docstring explaining:
- Purpose of the class
- Usage examples
- Requirements for the

Here's the suggested improvement:

86-97: Consider adding validation to ensure value compatibility.To improve robustness, consider validating that the wrapped value supports the required protocols during initialization. This would prevent runtime errors when array operations are attempted on incompatible values.
Example implementation:
def __init__(self, value: Any): """Initialize with validation for required protocols. Parameters ---------- value : Any A value that supports Array API and DLPack protocols Raises ------ TypeError If value doesn't support required protocols """ required_methods = ['__array__', '__array_namespace__', '__dlpack__', '__dlpack_device__'] missing = [method for method in required_methods if not hasattr(value, method)] if missing: raise TypeError(f"Value must support {', '.join(missing)} methods") super().__init__(value)deepmd/jax/descriptor/dpa1.py (3)

32-36: Consider adding type validation before deserialization.While the deserialization logic is correct, it might be safer to verify that the value has a
serializemethod before attempting to use it. This could prevent cryptic errors if an invalid value is passed.def __setattr__(self, name: str, value: Any) -> None: if name in {"in_proj", "out_proj"}: + if not hasattr(value, 'serialize'): + raise ValueError(f"Expected serializable object for {name}, got {type(value)}") value = NativeLayer.deserialize(value.serialize()) return super().__setattr__(name, value)
Line range hint
50-56: Consider optimizing list comprehension and adding validation.The current implementation could be improved for better efficiency and safety:
- Validate that value is a list before processing
- Use generator expression instead of list comprehension for memory efficiency with large lists
def __setattr__(self, name: str, value: Any) -> None: if name == "attention_layers": + if not isinstance(value, (list, tuple)): + raise ValueError(f"Expected list for {name}, got {type(value)}") - value = [ - NeighborGatedAttentionLayer.deserialize(ii.serialize()) for ii in value - ] + value = list(NeighborGatedAttentionLayer.deserialize(ii.serialize()) + for ii in value if hasattr(ii, 'serialize')) return super().__setattr__(name, value)

68-81: LGTM: Comprehensive attribute handling with proper JAX integration.The implementation correctly handles various attribute types and ensures proper JAX compatibility. A few suggestions for improvement:
- Consider grouping related attributes in dictionaries for cleaner code
- Add docstring explaining the purpose of each attribute type

11-21: Verify ArrayAPIVariable serialization supportSince this function processes attributes for the new JAX checkpoint format, we should verify that
ArrayAPIVariableproperly supports serialization.✅ Verification successful
Let me gather more specific information about serialization in the JAX implementation.
This will help us understand:
- The complete implementation of ArrayAPIVariable
- The JAX-specific serialization utilities
- The base Variable class that ArrayAPIVariable extends
Let me check one more aspect to understand how the JAX model handles serialization through the base model class.
Based on the gathered information, I can now provide the final response:
ArrayAPIVariable provides sufficient serialization support through JAX ecosystem
The implementation shows that:
ArrayAPIVariableextendsnnx.Variableand implements the necessary array interface methods (__array__,__array_namespace__,__dlpack__)- JAX backend has dedicated serialization utilities in
deepmd/jax/utils/serialization.pythat handle model state serialization using the Orbax Checkpoint (ocp) system- The serialization is handled at the model level where variables are automatically included in the state dictionary through the JAX/Orbax checkpointing system
The reason for verification is that:
ArrayAPIVariableis properly integrated into JAX's array ecosystem through standard array protocol methods- The serialization is handled by JAX's robust checkpointing system (Orbax) which is designed to handle all JAX array types
- The implementation follows JAX's standard practices for model serialization, ensuring proper handling of all model variables

20-21: Verify compatibility with parent class implementation.The null check before wrapping in
ArrayAPIVariablelooks correct, but we should verify that this maintains compatibility with the parentAtomExcludeMaskDPclass's expectations.✅ Verification successful
Let me gather more information about the JAX implementation to ensure full compatibility.
Let me check one more thing to understand the inheritance hierarchy and the ArrayAPIVariable usage.
Let me check one final thing about the class inheritance.
The null check is compatible with parent class implementation
The verification confirms that:
- The JAX implementation (
AtomExcludeMask) inherits fromAtomExcludeMaskDP- The parent class uses
type_maskas a numpy array- The null check in
__setattr__safely handles the conversion:
- First converts to JAX array using
to_jax_array- Only wraps non-null values in
ArrayAPIVariable- Uses
super().__setattr__to maintain parent class behaviorThe change maintains compatibility while adding type safety for JAX-specific array handling.

ArrayAPIVariable-wrapped attributes are correctly handled during serialization/deserialization.✅ Verification successful
Let me try different search paths since the previous attempt didn't find the test directory.
Let's examine the ArrayAPIVariable class definition and the serialization implementation in JAX.
Based on the code analysis, I can now provide a final response:
ArrayAPIVariablewrapping is safe for serializationThe review concern can be resolved because:
ArrayAPIVariableis a thin wrapper around JAX arrays that only implements array protocol methods (__array__,__array_namespace__,__dlpack__, etc.)- The JAX serialization system (in
deepmd/jax/utils/serialization.py) handles model state through Orbax checkpointing, which works at a lower level with pure dictionaries- The test file

33-34: Verify consistent ArrayAPIVariable usageLet's verify that the
ArrayAPIVariablewrapping is consistently applied across the codebase for similar model parameters.✅ Verification successful
Let me gather more information to verify the consistency of ArrayAPIVariable usage, particularly focusing on the initialization and handling of model parameters.
This will help us understand:
- The overall usage pattern of ArrayAPIVariable
- If there's a consistent pattern for parameter initialization
- If there are any inconsistencies in how parameters are wrapped
Based on the comprehensive search results, I can now generate the final response:
ArrayAPIVariable usage is consistent across the codebase
The wrapping of values with
ArrayAPIVariablefollows a consistent pattern throughout the codebase:
- All numerical parameters are first converted using
to_jax_arrayand then wrapped withArrayAPIVariable- The pattern
if value is not None: value = ArrayAPIVariable(value)is consistently used in:
- Fitting parameters (bias_atom_e, fparam_avg, etc.)
- Descriptor parameters (mean, stddev, dstd, davg)
- Type embedding parameters (econf_tebd)
- Atomic model parameters (out_bias, out_std)

✅ Verification successful
Let me gather more specific information about the serialization implementation to verify the checkpoint functionality properly.
Based on the gathered information, I can now provide a final verification response.
Checkpoint serialization/deserialization implementation is properly structured and secure.
The implementation shows:
- A robust serialization utility (
serialization.py) using Orbax checkpoint handler for JAX models- Consistent serialization/deserialization pattern across the descriptor hierarchy
- Proper type conversion and error handling for JAX-specific formats
- Clean inheritance from DP implementations with appropriate JAX adaptations
The code in
dpa1.pycorrectly implements the checkpoint I/O by:
- Converting all nested components through their respective serialization methods
- Maintaining the component hierarchy during deserialization
- Properly handling special cases like environment matrices and masks
- Using type-safe conversions for arrays and network components
