Walkthrough

The recent updates to structuretoolkit/analyse/symmetry.py enhance the tensor symmetrization process by refining the symmetrize_tensor method and introducing several helper functions for improved tensor manipulation. Corresponding tests in tests/test_symmetry.py have also been updated to reflect these changes, including new symmetry operations and the removal of redundant test methods.

Changes

File Path Change Summary
structuretoolkit/analyse/symmetry.py Updated the symmetrize_tensor method; added _get_inner_slicer, _get_einsum_str; updated _get_outer_slicer, _back_order; removed _SymmetrizeTensor.
tests/test_symmetry.py Renamed class TestAtoms to TestSymmetry; removed TestSymmetrizeTensors and its test methods; added new test methods related to symmetry operations.

Poem

Tensors dance in symmetry,
A melody of math, you see,
New functions join the lively spree,
While obsolete ones take their leave,
Tests align in harmony,
Code refined, more clarity.

Line range hint 235-266: Address unused variable and verify tensor operations.

The variable v is defined but not used, which could be a mistake or leftover from a previous version of the code. Additionally, the tensor operations using np.einsum need to be verified for correctness, especially since they are crucial for the new functionality.

-        v = np.transpose(
-            tensor[_get_outer_slicer(tensor.shape, self.permutations)],
-            _back_order(tensor.shape, len(self._structure))
-        )
-        return np.einsum(
-            _get_einsum_str(tensor.shape, len(self._structure)),
-            *sum([s == len(self._structure) for s in tensor.shape]) * [self.rotations],
-            tensor,
-        )
+        # Assuming the intended use of `v` was in the einsum operation
+        return np.einsum(
+            _get_einsum_str(tensor.shape, len(self._structure)),

Line range hint 1-463: Verify coverage for new tensor symmetrization functionality.

The removal of the TestSymmetrizeTensors class raises concerns about whether the new tensor symmetrization functionality introduced in symmetry.py is adequately tested. It's crucial to ensure that the remaining tests or new tests cover this extended functionality.

429-433: Review the _get_inner_slicer function for correctness.

Ensure that the _get_inner_slicer function correctly generates slicing tuples as intended. This function is critical for tensor manipulation in symmetrize_tensor.

Verification successful

Verification of _get_inner_slicer function

The _get_inner_slicer function correctly generates slicing tuples as intended. It initializes a list of None values of length n, sets the first and i-th elements to slice(None), and returns the list as a tuple. This behavior aligns with the expected functionality for tensor manipulation in symmetrize_tensor.

  • The function definition is located in structuretoolkit/analyse/symmetry.py:
    • Line 429: def _get_inner_slicer(n, i):
    • Line 430: s = [None for nn in range(n)]
    • Line 431: s[0] = slice(None)
    • Line 432: s[i] = slice(None)
    • Line 433: return tuple(s)

450-461: Review the _back_order function for correctness.

The _back_order function reorders tensor indices. Verify that it correctly handles the reordering based on the tensor shape.


436-447: Review the _get_outer_slicer function for correctness.

The _get_outer_slicer function is used to generate slicing tuples for tensor operations. Verify that it handles different tensor shapes correctly.


463-473: Review the _get_einsum_str function for correctness.

The _get_einsum_str function generates the string for np.einsum operations. Ensure that it correctly constructs the string based on the tensor shape and structure.

426-430: Add comments for clarity in _get_inner_slicer.

The function appears to be correctly implemented for generating slicing indices. However, adding inline comments explaining the purpose of each step would enhance readability and maintainability.


433-444: Consider optimizing the _get_outer_slicer function.

While the function is correctly implemented, the loop and conditional checks might be optimized for better performance, especially for large tensors. Consider exploring alternatives that could simplify or speed up this slicing operation.


447-458: Refactor for simplicity in _back_order.

The function's logic is correct, but its complexity could hinder readability and maintainability. Consider refactoring to simplify the operations, possibly by breaking it down into smaller, more descriptive helper functions or by using more descriptive variable names.


460-470: Add detailed comments in _get_einsum_str.

This function cleverly constructs the einsum operation string dynamically. Given the complexity of the operations involved, adding detailed comments explaining how the einsum string is constructed would greatly aid in understanding and maintaining the code.


250-263: Remove unused variable and verify tensor operations.

The variable v is assigned but never used, which could be a leftover from debugging. Consider removing it to clean up the code.

-        v = np.transpose(
+        _ = np.transpose(

Also, ensure the complex numpy operations in this function are correctly handling the tensor symmetrization as intended. It might be beneficial to add more detailed comments or documentation explaining each step for future maintainability.

Line range hint 31-150: Review of New and Modified Test Methods

  1. Class Name Change: The renaming of the test class from TestAtoms to TestSymmetry is appropriate given the focus on symmetry operations. This change aligns the class name with its functionality, enhancing readability and maintainability.

  2. Method test_symmetrize_tensor: This new test method effectively checks the functionality of the symmetrize_tensor function by validating the properties of the symmetrized tensor:

    • The peak-to-peak (ptp) values being less than a very small threshold suggests correct symmetrization of tensor components.
    • The shape assertions ensure that the tensor dimensions are maintained correctly after symmetrization.
    • Using random data for tensors is a good practice as it tests the function under various scenarios. However, it might be beneficial to include some deterministic tests to ensure reproducibility and easier debugging.
    • The use of assertAlmostEqual for floating-point comparisons is appropriate, considering the precision issues inherent in such operations.
  3. Coverage and Exception Testing: The tests cover various scenarios, including error handling and boundary conditions. The use of assertRaises to check for expected exceptions when input conditions are not met is a good practice as it ensures robustness.

  4. Randomness in Tests: While using random numbers can simulate a wide range of inputs, it's also important to include specific, deterministic test cases that serve as clear examples of what is expected. This can aid in debugging and understanding the test suite.

    # Suggestion to add deterministic test cases alongside random ones
    deterministic_tensor = np.array([[1, 2, 3], [2, 1, 4], [3, 4, 1]])
    sym_tensor = symmetry.symmetrize_tensor(deterministic_tensor)
    expected_tensor = np.array([[...]])  # Expected symmetrized tensor
    self.assertTrue(np.allclose(sym_tensor, expected_tensor))
  5. Documentation and Comments: Adding comments within the test methods to explain the purpose of each assertion and the significance of the values being tested can greatly improve the maintainability and readability of the test code.

    # Example comment addition
    # Check that the diagonal elements of the symmetrized tensor have minimal variance, indicating proper symmetrization
    self.assertLess(sym_tensor.diagonal().ptp(), 1.0e-8)

Overall, the test suite modifications support the extended functionality of the symmetrize_tensor method effectively. The tests seem well-structured to validate the new capabilities, ensuring that the symmetrization process is both accurate and efficient.

@samwaseda Coverage decreased (-5.5%) why was this merged even though it is not covered by the tests?

The Github action coverage/coveralls for the commit Format black reports the coverage decreased, most likely because you deleted the _SymmetrizeTensor and the corresponding tests.
