Walkthrough

This pull request primarily introduces type annotations to several functions within the deepmd/pt/model/descriptor module, enhancing type safety and clarity regarding the expected input and output types. The functions tabulate_fusion_se_a, tabulate_fusion_se_atten, tabulate_fusion_se_r, and tabulate_fusion_se_t have been updated with specific types for their parameters and return values. Additionally, the DescrptBlockSeAtten class's constructor has been modified to remove an unnecessary parameter. The overall functionality and logic of the related classes remain unchanged.

Changes

File Change Summary
deepmd/pt/model/descriptor/se_a.py - Added type annotations to tabulate_fusion_se_a: parameters as torch.Tensor and int, return type as list[torch.Tensor].
deepmd/pt/model/descriptor/se_atten.py - Added type annotations to tabulate_fusion_se_atten: parameters as torch.Tensor, int, and bool, return type as list[torch.Tensor].
- Removed type parameter from DescrptBlockSeAtten constructor.
deepmd/pt/model/descriptor/se_r.py - Added type annotations to tabulate_fusion_se_r: parameters as torch.Tensor and int, return type as list[torch.Tensor].
deepmd/pt/model/descriptor/se_t.py - Added type annotations to tabulate_fusion_se_t: parameters as torch.Tensor and int, return type as list[torch.Tensor].
doc/freeze/compress.md - Added a new section "Requirements of installation" for PyTorch backend, detailing the installation of a customized OP library during model freezing.

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

132-132: Consider adding a complete example command.

To make the instructions more actionable, consider adding a complete example command showing how to set the environment variable:

 The customized OP library for the Python interface can be installed by setting environment variable {envvar}`DP_ENABLE_PYTORCH` to `1` during [installation](../install/install-from-source.md).
+
+```bash
+export DP_ENABLE_PYTORCH=1
+pip install .
+```
deepmd/pt/model/descriptor/se_a.py (1)

Line range hint 82-85: Consider enhancing the error message and documentation.

The error message could be more specific about which operation is missing and provide a direct link to the model compression documentation. Additionally, the LAMMPS compatibility note could be more prominent.

Consider updating the error message like this:

- "tabulate_fusion_se_a is not available since customized PyTorch OP library is not built when freezing the model. "
+ "The tabulate_fusion_se_a operation is not available. This operation requires the custom PyTorch operations library, which is not built. "
+ "Please refer to https://docs.deepmodeling.org/projects/deepmd/en/master/model-compression.html for details on model compression. "
deepmd/pt/model/descriptor/se_t.py (1)

76-80: Improve type annotations and documentation

While adding type annotations is good for type safety, consider these improvements:

  1. Use more descriptive parameter names instead of generic argumentN
  2. Add dimension information to tensor type hints using # shape: ... comments
  3. Add a docstring explaining the parameters and return value
-    argument0: torch.Tensor,
-    argument1: torch.Tensor,
-    argument2: torch.Tensor,
-    argument3: torch.Tensor,
-    argument4: int,
+    table_data: torch.Tensor,  # shape: [table_size, out_dim]
+    table_info: torch.Tensor,  # shape: [6]
+    env_deriv: torch.Tensor,  # shape: [batch_size, 1]
+    env: torch.Tensor,  # shape: [batch_size, n_types_i, n_types_j]
+    output_dim: int,

Also consider adding a docstring:

"""Fuse and tabulate the environment matrix for the SE(3) descriptor.

Parameters
----------
table_data : torch.Tensor
    The tabulated data for interpolation
table_info : torch.Tensor
    Configuration info containing [lower, upper, upper_ext, stride1, stride2, check_freq]
env_deriv : torch.Tensor
    Environment derivatives
env : torch.Tensor
    Environment matrix
output_dim : int
    Output dimension of the network

Returns
-------
list[torch.Tensor]
    List containing the fused descriptor values
"""
deepmd/pt/model/descriptor/se_atten.py (2)

55-61: Improve parameter names and add docstring.

While the type annotations are correct, the function would benefit from:

  1. More descriptive parameter names that indicate their purpose
  2. A docstring explaining the parameters and return value

Consider renaming parameters and adding documentation:

 def tabulate_fusion_se_atten(
-    argument0: torch.Tensor,
-    argument1: torch.Tensor,
-    argument2: torch.Tensor,
-    argument3: torch.Tensor,
-    argument4: torch.Tensor,
-    argument5: int,
-    argument6: bool,
+    compress_data: torch.Tensor,
+    compress_info: torch.Tensor,
+    input_data: torch.Tensor,
+    radial_data: torch.Tensor,
+    gate_data: torch.Tensor,
+    filter_neuron: int,
+    is_sorted: bool,
 ) -> list[torch.Tensor]:
+    """Fallback implementation for the custom tabulate_fusion_se_atten operation.
+    
+    Parameters
+    ----------
+    compress_data : torch.Tensor
+        Compressed network data
+    compress_info : torch.Tensor
+        Compression configuration information
+    input_data : torch.Tensor
+        Input tensor for the network
+    radial_data : torch.Tensor
+        Radial information tensor
+    gate_data : torch.Tensor
+        Gating tensor
+    filter_neuron : int
+        Number of filter neurons
+    is_sorted : bool
+        Whether the input data is sorted
+        
+    Returns
+    -------
+    list[torch.Tensor]
+        List of output tensors from the fusion operation
+    """

Line range hint 87-156: Remove deprecated type parameter.

The type parameter is immediately deleted after being passed to the constructor, indicating it's deprecated. For better code clarity:

  1. Remove the parameter from the constructor signature
  2. Remove its documentation from the docstring

Apply this change:

     def __init__(
         self,
         rcut: float,
         rcut_smth: float,
         sel: Union[list[int], int],
         ntypes: int,
         neuron: list = [25, 50, 100],
         axis_neuron: int = 16,
         tebd_dim: int = 8,
         tebd_input_mode: str = "concat",
         set_davg_zero: bool = True,
         attn: int = 128,
         attn_layer: int = 2,
         attn_dotr: bool = True,
         attn_mask: bool = False,
         activation_function="tanh",
         precision: str = "float64",
         resnet_dt: bool = False,
         scaling_factor=1.0,
         normalize=True,
         temperature=None,
         smooth: bool = True,
         type_one_side: bool = False,
         exclude_types: list[tuple[int, int]] = [],
         env_protection: float = 0.0,
         trainable_ln: bool = True,
         ln_eps: Optional[float] = 1e-5,
-        seed: Optional[Union[int, list[int]]] = None,
-        type: Optional[str] = None,
+        seed: Optional[Union[int, list[int]]] = None
     ):

Also remove the parameter from the docstring.

76-80: LGTM! Type annotations are accurate and helpful.

The type annotations correctly specify torch.Tensor for tensor arguments and int for the scalar argument, improving code clarity and type safety.
