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! 🎉👨‍💻

Hi @AliTarekk ,
Thanks for the PR, I have left a request considering the changes you have added. I also notice the tests for nanmean seems to be failing. Please feel free to request a re-review after the changes.

The tests seems to still be failing as shown in the run_tests (1) and display_test_results units of the CI checks. Please resolve them and the branch conflicts. Thanks and feel free to re-request a review
