Summary of Changes

Hello @samthakur587, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request implements support for the numpy.deg2rad function within the OpenVINO backend. Previously, this function was not supported, and attempting to use it would raise a NotImplementedError. With this change, users can now convert degrees to radians using OpenVINO operations, enhancing the backend's compatibility with NumPy functionalities.

Highlights

• Enable numpy.deg2rad support: The deg2rad function in keras/src/backend/openvino/numpy.py has been fully implemented to convert degree values to radians using OpenVINO operations, replacing the previous NotImplementedError.
• Update test exclusions: The test_deg2rad entries have been removed from the excluded_concrete_tests.txt file, indicating that the deg2rad functionality is now expected to pass tests within the OpenVINO backend.

Code Review

This pull request adds support for numpy.deg2rad to the OpenVINO backend. The implementation is well-structured and handles different input data types correctly. I've suggested a minor improvement to use np.pi for better precision and consistency, instead of a hardcoded value.

[gemini-code-assist]

For better precision and to maintain consistency with other parts of the codebase (e.g., arctan2), it's recommended to use np.pi instead of a hardcoded value for pi. This also makes the code more concise.

Suggested change

	pi = 3.14159265358979323846
	pi_over_180 = pi / 180.0
	pi_over_180 = np.pi / 180.0

@samthakur587 , can you rebase to merge changes to excluded_concrete_tests.txt? Then I can merge. Thanks!

[samthakur587]

@hertschuh done!
