deepmd/jax/utils/exclude_mask.py (1)
12-16: LGTM: Well-implemented class with custom attribute handling.The
PairExcludeMaskclass effectively extendsPairExcludeMaskDPand provides custom handling for thetype_maskattribute. The implementation ensures thattype_maskis always stored as a JAX array, which is crucial for compatibility with JAX-based operations.Consider using a set for faster lookup of attribute names:
class PairExcludeMask(PairExcludeMaskDP): + _jax_attributes = {"type_mask"} def __setattr__(self, name: str, value: Any) -> None: - if name in {"type_mask"}: + if name in self._jax_attributes: value = to_jax_array(value) return super().__setattr__(name, value)This change allows for easier extension if more attributes need similar handling in the future.
source/tests/array_api_strict/utils/exclude_mask.py (1)
14-17: LGTM with suggestions:__setattr__implementation is correct but could be more explicit.The
__setattr__method correctly overrides the parent class to provide custom behavior for thetype_maskattribute. However, consider the following suggestions:
- Add a docstring to explain the purpose of this override and what
to_array_api_strict_arraydoes.- Consider using a more explicit condition, such as
if name == "type_mask"instead ofif name in {"type_mask"}, unless you plan to add more attributes to this set in the future.Here's a suggested improvement:
def __setattr__(self, name: str, value: Any) -> None: """ Override __setattr__ to ensure 'type_mask' is converted to a strict array API compliant array. This method intercepts assignments to 'type_mask' and applies the to_array_api_strict_array conversion before setting the attribute. All other attributes are set normally. Args: name (str): The name of the attribute being set. value (Any): The value to assign to the attribute. """ if name == "type_mask": value = to_array_api_strict_array(value) return super().__setattr__(name, value)source/tests/array_api_strict/common.py (3)
10-10: Consider adding the return type to the function signature.While the docstring specifies the return type, it would be beneficial to add it to the function signature as well for better type hinting.
Consider updating the function signature as follows:
def to_array_api_strict_array(array: Optional[np.ndarray]) -> Optional[array_api_strict.Array]:This change will provide more explicit type information and improve code readability.
11-22: Improve docstring for consistency and accuracy.The docstring is well-structured, but there are a few inconsistencies that should be addressed:
- The parameter type should be
Optional[np.ndarray]to match the function signature.- The return type should be
Optional[array_api_strict.Array]to accurately reflect the function's behavior and the use ofarray_api_strict.- The docstring should mention that the function returns
Noneif the input isNone.Consider updating the docstring as follows:
""" Convert a numpy array to a JAX array. Parameters ---------- array : Optional[np.ndarray] The numpy array to convert, or None. Returns ------- Optional[array_api_strict.Array] The JAX array, or None if the input is None. """These changes will improve the accuracy and consistency of the documentation.
23-25: LGTM: Implementation is correct and concise.The function correctly handles the case where the input is None and uses the appropriate method to convert the array.
Consider adding explicit error handling for invalid input types. For example:
def to_array_api_strict_array(array: Optional[np.ndarray]) -> Optional[array_api_strict.Array]: if array is None: return None if not isinstance(array, np.ndarray): raise TypeError(f"Expected np.ndarray or None, got {type(array)}") return array_api_strict.asarray(array)This addition would make the function more robust against potential misuse.
deepmd/jax/common.py (1)
Line range hint
23-33: Update the docstring to reflect optional input and output.The function signature has been updated to handle optional input and output, but the docstring doesn't reflect this change. Please update the docstring to accurately describe the new behavior.
Here's a suggested update for the docstring:
def to_jax_array(array: Optional[np.ndarray]) -> Optional[jnp.ndarray]: """Convert a numpy array to a JAX array or handle None input. Parameters ---------- array : Optional[np.ndarray] The numpy array to convert, or None. Returns ------- Optional[jnp.ndarray] The JAX tensor, or None if the input is None. """source/tests/array_api_strict/utils/type_embed.py (1)
17-22: LGTM with suggestions: Custom attribute setting looks good.The
__setattr__method implementation effectively customizes attribute setting for "econf_tebd" and "embedding_net". This approach aligns well with the PR objective of implementing JAX or Array API compatibility.Suggestions for improvement:
- Consider using a more specific type hint for the
valueparameter instead ofAnyto improve type safety.- The serialization and deserialization of "embedding_net" might benefit from a comment explaining its purpose (e.g., creating a deep copy or ensuring a specific format).
Here's a suggested improvement for the method signature:
from typing import Union from numpy import ndarray from jax import Array def __setattr__(self, name: str, value: Union[ndarray, Array, EmbeddingNet]) -> None:This change would provide more specific type hinting for the
valueparameter, improving type safety and code readability.deepmd/jax/utils/network.py (1)
44-45: LGTM: LayerNorm class is correctly implemented.The LayerNorm class effectively combines functionalities from LayerNormDP and NativeLayer through multiple inheritance. The empty class body is appropriate as no additional methods or attributes are needed.
Consider adding a docstring to explain the purpose of this class and its inheritance structure. For example:
class LayerNorm(LayerNormDP, NativeLayer): """ A layer normalization class that combines functionality from LayerNormDP and NativeLayer. This class inherits methods and properties from both parent classes without modification. """ passsource/tests/array_api_strict/utils/network.py (1)
29-29: Nitpick: Redundantreturnstatement in__setattr__method.In the
__setattr__method, thereturnstatement is unnecessary becausesuper().__setattr__(name, value)does not return a meaningful value (it returnsNone). Omitting thereturnstatement can improve readability.Apply this diff to remove the redundant
returnstatement:- return super().__setattr__(name, value) + super().__setattr__(name, value)deepmd/jax/descriptor/dpa1.py (1)
65-67: Clarify the handling of theenv_matattribute.The attribute
env_mathas a comment indicating it doesn't store any value, followed by apassstatement. To enhance code clarity, consider explicitly settingvaluetoNoneforenv_mat.Apply this diff for explicit assignment:
elif name == "env_mat": # env_mat doesn't store any value + value = None passdeepmd/dpmodel/utils/exclude_mask.py (2)
118-130: Ensure consistent behavior of complex array operations across backendsThe sequence of array operations involving
xp.concat,xp.reshape,xp.where,xp.take, and advanced indexing should be verified for consistency across all supported array backends. Differences in backend implementations could lead to subtle bugs or unexpected behavior.
126-126: Remove commented-out code to improve code cleanlinessThe line
# type_j = xp.take_along_axis(ae, index, axis=1).reshape(nf, nloc, nnei)appears to be obsolete. Removing commented-out code enhances readability and maintainability.deepmd/dpmodel/utils/nlist.py (5)
101-103: Simplify the conditional assignment ofxmaxusing a ternary operatorTo make the code more concise, consider using a ternary operator for assigning
xmax.Apply this diff to simplify the code:
-if coord.size > 0: - xmax = xp.max(coord) + 2.0 * rcut -else: - xmax = 2.0 * rcut +xmax = xp.max(coord) + 2.0 * rcut if coord.size > 0 else 2.0 * rcutTools
Ruff
100-103: Use ternary operator
xmax = xp.max(coord) + 2.0 * rcut if coord.size > 0 else 2.0 * rcutinstead ofif-else-blockReplace
if-else-block withxmax = xp.max(coord) + 2.0 * rcut if coord.size > 0 else 2.0 * rcut(SIM108)
276-276: Includecellin array namespace initializationWhen initializing the array namespace with
array_api_compat, include all arrays (coord,atype,cell) to ensure they are compatible within the function.Apply this diff to include
cell:-xp = array_api_compat.array_namespace(coord, atype) +xp = array_api_compat.array_namespace(coord, atype, cell)
308-309: Usexp.transposeinstead ofxp.permute_dimsfor better compatibilityThe function
xp.transposeis commonly used across different array libraries and enhances readability.Apply this diff to use
xp.transpose:-shift_vec = xp.permute_dims(shift_vec, (1, 0, 2)) +shift_vec = xp.transpose(shift_vec, (1, 0, 2))
92-93: Correct the typo in the comment: 'implemantation' to 'implementation'There's a typo in the comment; 'implemantation' should be 'implementation'.
Apply this diff to correct the typo:
-## translated from torch implemantation by chatgpt +## Translated from Torch implementation by ChatGPT
97-98: Fix spelling errors in docstringsThere are several typos in the docstrings, such as 'neightbor' instead of 'neighbor' and 'exptended' instead of 'extended'.
Apply this diff to correct the typos:
-"""Build neightbor list for a single frame. keeps nsel neighbors. Parameters ---------- coord : np.ndarray exptended coordinates of shape [batch_size, nall x 3] ... +"""Build neighbor list for a single frame. Keeps nsel neighbors. Parameters ---------- coord : np.ndarray extended coordinates of shape [batch_size, nall x 3] ...This improves the readability and professionalism of the documentation.

83-83: Add docstring forarray_api_strict_classTo maintain consistency with other class variables, please add a docstring for
array_api_strict_class.Apply this diff to add the docstring:
array_api_strict_class: ClassVar[Optional[type]] +"""Array API Strict model class."""

267-273: Update docstring to reflect the new order of reference backendsThe docstring for
get_reference_backendlists the order of checking as "Order of checking for ref: DP, TF, PT." Since you've added JAX andARRAY_API_STRICT, please update the docstring to reflect the current order.Apply this diff to update the docstring:

This implementation follows good practices and can be useful for dynamic network creation or configuration.
Line range hint
1-45: Summary: JAX-specific network implementations added successfully.The changes in this file introduce JAX-specific implementations of NetworkCollection and LayerNorm classes, extending the existing DeepMD functionality. These additions are consistent with the PR objective (feat(jax/array-api): dpa1) and follow good coding practices. The new classes leverage multiple inheritance and type hinting to create a clear and maintainable structure.
Key points:
- NetworkCollection provides a mapping between string identifiers and network types, which can facilitate dynamic network creation or configuration.
- LayerNorm combines functionality from LayerNormDP and NativeLayer, potentially allowing for JAX-specific optimizations.
These changes appear to be a solid foundation for integrating JAX capabilities into the DeepMD framework. As the feature develops, ensure that any JAX-specific optimizations or behaviors are well-documented for users transitioning from the standard DeepMD implementation.
source/tests/common/dpmodel/test_descriptor_dpa1.py (1)
40-57: LGTM! Well-structured test for multi-frame consistency.The new test method
test_multiple_framesis well-structured and effectively tests the consistency ofDescrptDPA1across multiple frames. It properly initializes the descriptor, prepares multi-frame input data, and asserts the consistency of the output.Enhance error messages for easier debugging.
Consider improving the error messages in the assertions to provide more context about the failing comparisons.
You could modify the error messages as follows:
- np.testing.assert_allclose(mm0[ii][0], mm0[ii][2], err_msg=f"{ii} 0~2") - np.testing.assert_allclose(mm0[ii][1], mm0[ii][3], err_msg=f"{ii} 1~3") + np.testing.assert_allclose(mm0[ii][0], mm0[ii][2], err_msg=f"Mismatch in output {ii} between frame 0 and 2") + np.testing.assert_allclose(mm0[ii][1], mm0[ii][3], err_msg=f"Mismatch in output {ii} between frame 1 and 3")Add a comment explaining the test's purpose.
It would be helpful to add a brief comment explaining the purpose of this test method at the beginning.
Consider adding a docstring like this:
def test_multiple_frames(self): """ Test that DescrptDPA1 produces consistent output across multiple frames. This test duplicates the input data to create a two-frame scenario and verifies that the output for both frames is identical. """Verify the correctness of frame duplication.
The test assumes that duplicating the input data (coord_ext, atype_ext, nlist) correctly represents multiple frames. It's important to ensure this approach accurately simulates multi-frame behavior in the actual use case.
To verify this, we can check if there are any frame-specific operations in the
DescrptDPA1class:If this search returns results, it might indicate that the current test method doesn't fully capture the multi-frame behavior, and we may need to adjust the test accordingly.
Verification successful
Frame duplication approach is valid and effective for multi-frame testing.
The extensive code search results provide strong evidence that the
DescrptDPA1class and related components are designed to handle multiple frames. Thetest_multiple_framesmethod intest_descriptor_dpa1.pyappropriately leverages this capability by duplicating input data to create a two-frame scenario. This approach is consistent with how multi-frame data is processed throughout the codebase, as evidenced by numerousnframes-related operations and reshaping. The test method effectively verifies the descriptor's behavior across multiple frames, which is crucial for ensuring the model's performance in real-world scenarios with varying numbers of atoms and frames.Scripts executed

compute_input_statsmethod is not implemented and raises a NotImplementedError. This suggests that this functionality is not yet available or needs to be implemented in the future.The
set_stat_mean_and_stddevandget_stat_mean_and_stddevmethods are correctly implemented, delegating to the se_atten attribute, which is consistent with the class design.Would you like assistance in implementing the
compute_input_statsmethod or creating a GitHub issue to track this task?

407-501: Replacexp.concatwithxp.concatenatefor array API complianceThe
callmethod is well-implemented and correctly computes the descriptor based on the input data. The use ofarray_api_compatenhances compatibility across different array libraries, which is a good practice.However, there are several instances where
xp.concatis used. For better compliance with the array API standard, these should be replaced withxp.concatenate.Please apply the following changes:
- grrg = xp.concat( + grrg = xp.concatenate(- ss = xp.concat([ss, atype_embd_nlist, atype_embd_nnei], axis=-1) + ss = xp.concatenate([ss, atype_embd_nlist, atype_embd_nnei], axis=-1)- ss = xp.concat([ss, atype_embd_nlist], axis=-1) + ss = xp.concatenate([ss, atype_embd_nlist], axis=-1)- tt = xp.concat([atype_embd_nlist, atype_embd_nnei], axis=-1) + tt = xp.concatenate([atype_embd_nlist, atype_embd_nnei], axis=-1)These changes will ensure consistency with the array API standard across different backend implementations.

563-605: Remove unused variable and approve deserialization implementationThe
deserializeclass method is well-implemented, correctly reconstructing a DescrptDPA1 object from a serialized dictionary. The version compatibility check is a good practice, and the reconstruction of nested objects is handled properly.However, there's an unused variable that should be removed:
- env_mat = data.pop("env_mat")This line assigns a value to
env_mat, but the variable is never used afterwards. Removing it will clean up the code and eliminate unnecessary assignments.Overall, the deserialization process is comprehensive and correct.
Line range hint
633-1445: Replace remainingxp.concatwithxp.concatenateand approve class implementationsThe implementations of
DescrptBlockSeAtten,NeighborGatedAttention,NeighborGatedAttentionLayer, andGatedAttentionLayerclasses are correct and consistent with the overall descriptor design. They properly implement the necessary methods for initialization, computation, serialization, and deserialization.However, there are a few remaining instances of
xp.concatthat should be replaced withxp.concatenatefor consistency with the array API standard:In the
DescrptBlockSeAttenclass:- ss = xp.concat([ss, atype_embd_nlist, atype_embd_nnei], axis=-1) + ss = xp.concatenate([ss, atype_embd_nlist, atype_embd_nnei], axis=-1)- ss = xp.concat([ss, atype_embd_nlist], axis=-1) + ss = xp.concatenate([ss, atype_embd_nlist], axis=-1)- tt = xp.concat([atype_embd_nlist, atype_embd_nnei], axis=-1) + tt = xp.concatenate([atype_embd_nlist, atype_embd_nnei], axis=-1)These changes will ensure consistency across the entire implementation.
Overall, the classes are well-implemented, with proper use of array operations and attention mechanisms. The serialization and deserialization methods for each class ensure that the model state can be correctly saved and loaded.

9-10: LGTM: Enhanced array compatibilityThe addition of
array_api_compatimport is a good step towards improving compatibility with different array libraries, which aligns well with the overall changes in this file.
94-96: LGTM: Flexible array operationsThe introduction of
xpusingarray_api_compat.array_namespaceenhances flexibility in array operations. The reshaping ofcoordmaintains consistency with the original implementation while leveraging the new array API.
115-116: Optimize distance calculation using broadcastingThe current calculation of
diffis correct but may consume significant memory for large arrays.As suggested in a previous review, consider optimizing the operation to improve performance:
-diff = ( - xp.reshape(coord1, [batch_size, -1, 3])[:, None, :, :] - - xp.reshape(coord0, [batch_size, -1, 3])[:, :, None, :] -) +coord1_reshaped = xp.reshape(coord1, (batch_size, -1, 3)) +coord0_reshaped = xp.reshape(coord0, (batch_size, -1, 3)) +diff = coord0_reshaped[:, :, xp.newaxis, :] - coord1_reshaped[:, xp.newaxis, :, :]This optimization reduces the need for large intermediate arrays and takes advantage of broadcasting for better efficiency.
131-144: LGTM: Consistent use of array API for padding and maskingThe changes in this segment effectively adapt the padding and masking operations to use the new array API. The logic remains consistent with the original implementation, while leveraging
xpmethods likexp.logical_orandxp.where. This ensures compatibility and maintains the intended functionality.
161-178: LGTM: Effective adaptation of type distinction logic to array APIThe changes in the
nlist_distinguish_typesfunction successfully adapt the atom type distinction logic to use the new array API. The use ofxpmethods likexp.tile,xp.take_along_axis, andxp.argsortis appropriate and maintains the original functionality while ensuring compatibility with different array libraries.
276-283: LGTM: Consistent adaptation to array API in ghost coordinate extensionThe changes in this segment of
extend_coord_with_ghostsfunction effectively adapt the initial setup and the handling of thecell is Nonecase to use the new array API. The use ofxpmethods maintains the original logic while ensuring compatibility with different array libraries.
285-292: LGTM: Effective adaptation of array operations in coordinate extensionThe changes in this segment successfully adapt the array reshaping and
nbuffcalculations to use the new array API. The use ofxpmethods for operations likereshape,astype, andarangeis appropriate and maintains the original functionality while ensuring compatibility with different array libraries.
302-317: LGTM: Effective adaptation of complex array operationsThe changes in this final segment successfully adapt complex array operations to use the new array API. Notable improvements include:
- Appropriate use of
xpmethods for array manipulations.- Replacement of
einsumwithtensordot, which maintains the original functionality while being compatible with the array API.These changes ensure compatibility with different array libraries while preserving the intended behavior of the
extend_coord_with_ghostsfunction.

1-317: Summary: Successful adaptation to array API with minor improvements neededThe changes in this file effectively adapt the neighbor list calculations to use the
array_api_compatlibrary, improving compatibility with different array libraries. The majority of the changes are well-implemented and maintain the original functionality.Key points:
- Consistent use of the
xpnamespace for array operations.- Appropriate adaptation of complex calculations to the new API.
- Maintained logic and functionality throughout the changes.
However, a few areas require attention:
- Potential optimization of the
diffcalculation for memory efficiency.- Addressing the use of
xp.eyefor non-square matrices.- Correcting the use of
xp.linalg.outertoxp.outer.Addressing these minor issues will further improve the code's robustness and efficiency. Overall, the transition to the array API is a positive change that enhances the flexibility and compatibility of the codebase.

119-123:⚠️ Potential issuePotential issue with
xp.eyefor non-square matricesThe changes to use
xp.linalg.vector_normandxpsorting methods are appropriate adaptations to the new array API. However, there's a potential issue with the use ofxp.eye.As noted in a previous review, the use of
xp.eye(nloc, nall, dtype=diff.dtype)may raise an error ifnlocandnallare not equal, as theeyefunction in the Array API standard typically supports only square matrices.Consider replacing this line with an alternative approach:
-rr -= xp.eye(nloc, nall, dtype=diff.dtype)[xp.newaxis, :, :] +# Create a mask to set self-distances to a large value +self_mask = xp.arange(nloc)[:, xp.newaxis] == xp.arange(nall) +rr += xp.where(self_mask, xp.inf, 0)[xp.newaxis, :, :]This ensures that self-distances are effectively ignored during sorting without relying on
xp.eyefor non-square matrices.
293-301:⚠️ Potential issueIncorrect use of
xp.linalg.outerinstead ofxp.outerAs noted in a previous review, the
outerfunction should be called from the top-level namespacexp, not fromxp.linalg. Usingxp.linalg.outermay result in anAttributeError.Please apply the following changes to fix the function calls:
-xyz = xp.linalg.outer(xi, xp.asarray([1, 0, 0]))[:, xp.newaxis, xp.newaxis, :] +xyz = xp.outer(xi, xp.asarray([1, 0, 0]))[:, xp.newaxis, xp.newaxis, :] ... -xyz = xyz + xp.linalg.outer(yi, xp.asarray([0, 1, 0]))[xp.newaxis, :, xp.newaxis, :] +xyz = xyz + xp.outer(yi, xp.asarray([0, 1, 0]))[xp.newaxis, :, xp.newaxis, :] ... -xyz = xyz + xp.linalg.outer(zi, xp.asarray([0, 0, 1]))[xp.newaxis, xp.newaxis, :, :] +xyz = xyz + xp.outer(zi, xp.asarray([0, 0, 1]))[xp.newaxis, xp.newaxis, :, :]This ensures compatibility with the Array API, as

65-69: Improvednp_softmaxfunction with better compatibility and NaN handlingThe changes to the
np_softmaxfunction enhance its compatibility across different array libraries and improve its robustness by explicitly handling NaN values. These are positive improvements.However, there's a minor optimization opportunity:
Consider combining the NaN handling and the exponential calculation to reduce the number of operations:
- x = xp.where(xp.isnan(x), xp.zeros_like(x), x) - e_x = xp.exp(x - xp.max(x, axis=axis, keepdims=True)) + max_x = xp.max(xp.where(xp.isnan(x), -xp.inf, x), axis=axis, keepdims=True) + e_x = xp.exp(xp.where(xp.isnan(x), 0, x - max_x))This change would handle NaN values and compute the exponential in a single pass, potentially improving performance.
986-1029: Comprehensive serialization method for DescrptDPA1The new
serializemethod provides a comprehensive way to convert theDescrptDPA1object into a dictionary format. This is crucial for saving and loading models, and the method covers all relevant attributes, including special handling for the "strip" mode.To improve maintainability, consider using a constant for the version number:
+ VERSION = 1 ... - "@version": 1, + "@version": self.VERSION,This would make it easier to update the version number in the future if needed.
1031-1055: Robust deserialization method for DescrptDPA1The new
deserializeclass method provides a robust way to reconstruct aDescrptDPA1object from a serialized dictionary. The method includes version compatibility checks and correctly handles special cases like the "strip" mode.Consider adding error handling for missing keys in the input dictionary:
+ required_keys = ["embeddings", "attention_layers", "env_mat", "tebd_input_mode"] + for key in required_keys: + if key not in data: + raise ValueError(f"Missing required key '{key}' in serialized data")This would make the deserialization process more robust against incomplete or corrupted input data.

1349-1405: ImprovedGatedAttentionLayer.callmethod with better compatibility and potential performance enhancementsThe changes to the
callmethod enhance its compatibility across different array libraries by usingarray_api_compat. The manual linear projection and explicit reshaping operations are likely to be more efficient. These changes improve the overall quality and potential performance of the function.Consider using
xp.einsumfor the matrix multiplications, which might be more readable and potentially more efficient:- attn_weights = q @ xp.permute_dims(k, (0, 1, 3, 2)) + attn_weights = xp.einsum('bhid,bhjd->bhij', q, k) - o = attn_weights @ v + o = xp.einsum('bhij,bhjd->bhid', attn_weights, v)This change would make the operations more explicit and might allow for better optimizations by the underlying array library.

8-17: Consider documenting the rationale for introducing Flax'snnx.The addition of
nnxfrom Flax suggests a shift towards using Flax for JAX-based modules. To ensure clarity for all team members and future contributors, it would be beneficial to document:
- The rationale behind introducing Flax's
nnx.- The expected benefits and use cases within the project.
- Any architectural or development practice changes this introduction might entail.
This documentation could be added as a comment in this file or in a separate document (e.g., README or ARCHITECTURE.md).
deepmd/jax/utils/type_embed.py (2)
Line range hint
18-24: LGTM:__setattr__implementation, with a suggestion for improvement.The
__setattr__method is well-implemented, handling specific attributes appropriately:
econf_tebdis converted to a JAX array.embedding_netis serialized and deserialized, likely to ensure compatibility with Flax.The use of type annotations and
super().__setattr__is commendable.Consider adding a brief comment explaining the rationale behind the special handling of
econf_tebdandembedding_net. This would improve code maintainability. For example:def __setattr__(self, name: str, value: Any) -> None: # Convert econf_tebd to JAX array for compatibility if name == "econf_tebd": value = to_jax_array(value) # Ensure embedding_net is properly serialized for Flax compatibility elif name == "embedding_net": value = EmbeddingNet.deserialize(value.serialize()) return super().__setattr__(name, value)
Line range hint
1-24: Overall assessment: Changes align with PR objectives and improve JAX/Flax integration.The modifications to
TypeEmbedNetsuccessfully integrate Flax functionality:
- The
@flax_moduledecorator likely enhances support for parameter initialization and backward propagation.- The
__setattr__method ensures proper handling of JAX arrays and Flax-compatible serialization.These changes align well with the PR objectives of using Flax for JAX-implemented modules. The implementation is correct and consistent with the stated goals.
To further improve this implementation:
- Consider adding documentation explaining the benefits of using the
@flax_moduledecorator for this specific class.- Add comments in the
__setattr__method to clarify the rationale behind the special handling ofeconf_tebdandembedding_net.- If not already present, consider adding unit tests to verify the correct behavior of the Flax integration, especially focusing on the serialization and deserialization of the
embedding_netattribute.deepmd/jax/utils/network.py (6)
25-31: LGTM: NativeLayer implementation looks good.The
NativeLayerclass is correctly decorated with@flax_moduleand inherits fromNativeLayerDP. The custom__setattr__method appropriately converts specific attributes to JAX arrays usingto_jax_array.Consider using a set for faster lookup of attribute names:
CONVERT_TO_JAX = {"w", "b", "idt"} def __setattr__(self, name: str, value: Any) -> None: if name in CONVERT_TO_JAX: value = to_jax_array(value) return super().__setattr__(name, value)This change would slightly improve performance, especially if the method is called frequently.
33-35: LGTM: NativeNet class is correctly defined.The
NativeNetclass is appropriately decorated with@flax_moduleand inherits from the result ofmake_multilayer_network(NativeLayer, NativeOP). This structure aligns with the PR objectives of implementing JAX-specific versions of existing classes.Consider adding a docstring to explain the purpose of this class and its relationship to the parent class:
@flax_module class NativeNet(make_multilayer_network(NativeLayer, NativeOP)): """ A JAX-compatible implementation of a multi-layer network. This class inherits all functionality from the parent class created by make_multilayer_network, using NativeLayer and NativeOP as building blocks. """ pass
38-40: LGTM: EmbeddingNet class is correctly defined.The
EmbeddingNetclass is appropriately decorated with@flax_moduleand inherits from the result ofmake_embedding_network(NativeNet, NativeLayer). This structure is consistent with the implementation of JAX-specific versions of existing classes.Consider adding a docstring to explain the purpose of this class and its relationship to the parent class:
@flax_module class EmbeddingNet(make_embedding_network(NativeNet, NativeLayer)): """ A JAX-compatible implementation of an embedding network. This class inherits all functionality from the parent class created by make_embedding_network, using NativeNet and NativeLayer as building blocks. """ pass
43-45: LGTM: FittingNet class is correctly defined.The
FittingNetclass is appropriately decorated with@flax_moduleand inherits from the result ofmake_fitting_network(EmbeddingNet, NativeNet, NativeLayer). This structure is consistent with the implementation of JAX-specific versions of existing classes.Consider adding a docstring to explain the purpose of this class and its relationship to the parent class:
@flax_module class FittingNet(make_fitting_network(EmbeddingNet, NativeNet, NativeLayer)): """ A JAX-compatible implementation of a fitting network. This class inherits all functionality from the parent class created by make_fitting_network, using EmbeddingNet, NativeNet, and NativeLayer as building blocks. """ pass
48-54: LGTM: NetworkCollection class is well-structured.The
NetworkCollectionclass is appropriately decorated with@flax_moduleand inherits fromNetworkCollectionDP. TheNETWORK_TYPE_MAPclass variable provides a centralized way to map network types to their JAX-specific implementations, which is a good design choice.Consider adding a docstring to explain the purpose of this class and the
NETWORK_TYPE_MAP:@flax_module class NetworkCollection(NetworkCollectionDP): """ A collection of JAX-compatible network implementations. This class provides a mapping between network type identifiers and their corresponding JAX-specific implementations. """ NETWORK_TYPE_MAP: ClassVar[Dict[str, type]] = { "network": NativeNet, "embedding_network": EmbeddingNet, "fitting_network": FittingNet, }Additionally, you might want to consider using an Enum for the network type keys to prevent typos and improve type checking:
from enum import Enum, auto class NetworkType(Enum): NETWORK = auto() EMBEDDING_NETWORK = auto() FITTING_NETWORK = auto() NETWORK_TYPE_MAP: ClassVar[Dict[NetworkType, type]] = { NetworkType.NETWORK: NativeNet, NetworkType.EMBEDDING_NETWORK: EmbeddingNet, NetworkType.FITTING_NETWORK: FittingNet, }
57-59: LGTM: LayerNorm class is correctly defined.The
LayerNormclass is appropriately decorated with@flax_moduleand inherits from bothLayerNormDPandNativeLayer. This multiple inheritance structure effectively combines the functionality ofLayerNormDPwith the JAX-specificNativeLayer.Consider adding a docstring to explain the purpose of this class and its relationship to the parent classes:
@flax_module class LayerNorm(LayerNormDP, NativeLayer): """ A JAX-compatible implementation of Layer Normalization. This class combines the functionality of LayerNormDP with the JAX-specific features of NativeLayer to provide a layer normalization implementation compatible with the JAX ecosystem. """ passdeepmd/jax/common.py (1)
44-77: Good implementation, but consider improving class initialization.The
flax_modulefunction is well-implemented and documented. The use of a dynamic metaclass to handle multiple inheritance is a good approach. However, there's a potential issue with the class creation.Consider modifying the
FlaxModuleclass to properly initialize both parent classes. Here's a suggested improvement:class FlaxModule(module, nnx.Module, metaclass=MixedMetaClass): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) nnx.Module.__init__(self)This ensures that both
moduleandnnx.Moduleare properly initialized.

140-140: LGTM: Addition of Flax dependency aligns with PR objectivesThe addition of Flax (>=0.8.0) as a dependency for Python versions 3.10 and above is a good choice. This aligns with the discussion in the PR comments about using Flax for modules implemented by JAX. Flax provides a structure similar to
torch.nn.Module, which can enhance support for parameter initialization and backward propagation in JAX-based implementations.source/tests/array_api_strict/utils/network.py (3)
36-42: LGTMThe
NetworkCollectionclass and itsNETWORK_TYPE_MAPare well-defined, providing a clear mapping of network types to their corresponding classes.
44-45: Verify method resolution order (MRO) forLayerNormIn the multiple inheritance of
class LayerNorm(LayerNormDP, NativeLayer), the order of base classes affects the method resolution order. Verify that this order ensures the desired behavior, and that methods from bothLayerNormDPandNativeLayerare correctly inherited and invoked.Run the following script to inspect the inheritance hierarchy and confirm the MRO:
#!/bin/bash # Description: Inspect the class definition and inheritance of LayerNorm. # Search for the LayerNorm class definition. rg --type python -A 5 $'class LayerNorm' # Optionally, check other classes that inherit from LayerNormDP or NativeLayer. rg --type python -A 5 $'(LayerNormDP|NativeLayer)'
31-33: Verify compatibility of network constructors withNativeLayerEnsure that
make_multilayer_network,make_embedding_network, andmake_fitting_networkare compatible with the updatedNativeLayerclass. Confirm that these functions accept the new parameters and integrate smoothly with the modified layer definitions.Run the following script to check the definitions and usages of the network constructors:
deepmd/jax/utils/network.py (4)
27-39: Implementation ofArrayAPIParamenhances interoperabilityThe
ArrayAPIParamclass correctly extendsnnx.Paramand implements array interface methods such as__array__,__array_namespace__,__dlpack__, and__dlpack_device__. This ensures that parameters can seamlessly integrate with different array operations and backends, improving the flexibility and compatibility of the code.
41-49: Properly wrapping parameters inNativeLayerwithArrayAPIParamIn the
__setattr__method ofNativeLayer, the attributesw,b, andidtare suitably converted to JAX arrays usingto_jax_array(value). If the value is notNone, it is wrapped withArrayAPIParam. This approach ensures that these parameters support the necessary array interfaces for downstream computations.
64-71:NetworkCollectioncorrectly definesNETWORK_TYPE_MAPfor dynamic network selectionThe
NETWORK_TYPE_MAPinNetworkCollectionappropriately maps string identifiers to their corresponding network classes. The use ofClassVarwith explicit type hints ensures proper type checking. This setup facilitates dynamic selection and instantiation of different network types based on configuration.
73-74: Verify the method resolution order (MRO) in theLayerNormclassThe
LayerNormclass inherits from bothLayerNormDPandNativeLayer. Multiple inheritance can sometimes lead to unexpected behaviors if there are overlapping methods or attributes. Ensure that the MRO is as intended and that the correct methods from parent classes are being invoked.To inspect the MRO and confirm the inheritance hierarchy, run the following script:
This will output the MRO, helping you verify that the inheritance structure behaves as expected.

103-105: Consider simplifying theif-elseblock with a ternary operatorThe current
if-elsestatement can be condensed into a single line using a ternary operator for improved readability.🧰 Tools
🪛 Ruff
102-105: Use ternary operator
xmax = xp.max(coord) + 2.0 * rcut if coord.size > 0 else 2.0 * rcutinstead ofif-else-blockReplace
if-else-block withxmax = xp.max(coord) + 2.0 * rcut if coord.size > 0 else 2.0 * rcut(SIM108)
170-171: Ensure correct broadcasting inxp_take_along_axisand subsequent operationsIn the
nlist_distinguish_typesfunction, verify that the use ofxp_take_along_axisand the subsequentsqueeze()operation correctly handle the array dimensions. Improper squeezing might lead to unexpected behavior if dimensions are collapsed incorrectly.Please check the shapes of
tnlistbefore and after squeezing to ensure that they align with the expected dimensions for further processing.
295-303: Confirmed correct usage ofxp.linalg.outerThe use of
xp.linalg.outeris appropriate here, as per the Array API standard,outeris available in thelinalgnamespace and not in the main namespacexp.
123-125:⚠️ Potential issuePotential compatibility issue with
xp.eyefor non-square matricesThe use of
xp.eye(nloc, nall, dtype=diff.dtype)may not be supported across all array backends ifnlocandnallare not equal. Some implementations of the Array API'seyefunction only support creating square matrices.Please verify whether the array backends you intend to support allow non-square matrices with
xp.eye. If not, consider an alternative approach to exclude self-distances, such as creating a mask with broadcasting.source/tests/consistent/descriptor/test_dpa1.py (4)
196-224: Refactor duplicated parameter unpacking inskip_jaxmethodThe unpacking of
self.paramis repeated from lines 199 to 218, similar to other methods. Consider refactoring this into a helper method to improve maintainability.
226-257: Refactor duplicated parameter unpacking inskip_array_api_strictmethodLines 229 to 248 repeat the unpacking of
self.param. Refactoring this into a shared helper method can reduce code duplication and potential errors.
392-401:eval_jaxmethod implementation is correctThe
eval_jaxmethod correctly invokeseval_jax_descriptorwith the appropriate parameters. This ensures consistency with the evaluation methods of other backends.
402-411:eval_array_api_strictmethod implementation looks goodThe
eval_array_api_strictmethod appropriately callseval_array_api_strict_descriptorwith the necessary arguments, aligning with the structure of existing evaluation methods.source/tests/consistent/common.py (6)
13-15: Importfind_specappropriatelyThe import of
find_specfromimportlib.utilis correctly added to check for the presence of thearray_api_strictmodule.
39-39: Detectarray_api_strictinstallation usingfind_specProperly sets
INSTALLED_ARRAY_API_STRICTby checking ifarray_api_strictis installed.
63-63: IncludeINSTALLED_ARRAY_API_STRICTin public APIAdds
INSTALLED_ARRAY_API_STRICTto the__all__list, exposing it as part of the module's public interface.
191-191: AddARRAY_API_STRICTtoRefBackendenumThe addition of
ARRAY_API_STRICTto theRefBackendenum is appropriate and extends backend support.
257-261: Implement serialization method forarray_api_strictThe
get_array_api_strict_ret_serialization_from_clsmethod correctly retrieves return values and serialization data forarray_api_strict.
290-295: SupportARRAY_API_STRICTinget_reference_ret_serializationAdds handling for
ARRAY_API_STRICTinget_reference_ret_serialization, ensuring it can retrieve return values and serialization data.deepmd/dpmodel/descriptor/dpa1.py (1)

149-160: ApprovedThe deserialization logic correctly handles the assignment and reshaping of
w,b, andidt. Usingravel()ensures that these variables are flattened appropriately before being set to the object's attributes. The code is clear and maintains consistency.
369-373: ApprovedThe initialization of
self.wandself.bappropriately utilizes the array API namespace. The use ofxp.squeezeensures that the weight shape is maintained as[num_in]. Settingself.wandself.bwithxp.ones_likeandxp.zeros_likewhenuni_initisTrueis correct and ensures consistency across backends.
386-387: ApprovedThe
serializemethod now correctly usesto_numpy_arrayfor convertingself.wandself.b. This change ensures consistent serialization across different backends and maintains compatibility, addressing previous concerns.
481-486: ApprovedThe
layer_norm_numpymethod correctly employs the array API namespace for calculating the mean and variance. The use oftuple(range(-len(shape), 0))for theaxisparameter ensures that the normalization operates over the correct dimensions, accommodating inputs of varying shapes. The updated calculations enhance compatibility and maintain the functionality of layer normalization.
