Thanks for contributing to Ivy! 😊👏
Here are some of the important points from our Contributing Guidelines 📝:
1. Feel free to ignore the run_tests (1), run_tests (2), … jobs, and only look at the display_test_results job. 👀 It contains the following two sections:
- Combined Test Results: This shows the results of all the ivy tests that ran on the PR. ✔️
- New Failures Introduced: This lists the tests that are passing on main, but fail on the PR Fork. Please try to make sure that there are no such tests. 💪
2. The lint / Check formatting / check-formatting tests check for the formatting of your code. 📜 If it fails, please check the exact error message in the logs and fix the same. ⚠️🔧
3. Finally, the test-docstrings / run-docstring-tests check for the changes made in docstrings of the functions. This may be skipped, as well. 📚
Happy coding! 🎉👨‍💻

Hey @AryanSharma21! Thanks for contributing!

Yeah the tests seem to be passing locally no problem there, however it seems that the function arguments are a bit different from the ones used on the original implementation could you please modify the arguments so that they match the original ones?

Other than that the PR looks in good shape!
Thanks! :)

Hello @danielmunioz , thanks for pointing this out. I have removed the dtype argument here and re-tested, Is there anything else that needs to be fixed please let me know.

[danielmunioz]

Hey! @AryanSharma21! Yeah, looks good now, just a minor extra letter on keepdims, paddle uses keepdim instead, but no worries, I'll take care of that little thing!

Other than that, the PR looks good to me!
Merging now! 🚀

Thanks for contributing :)
