Issue #15878

What does this implement/fix? Explain your changes.

This implement fixes the Macro average error which was being caused due to the missing zero_division argument here.

Any other comments?

It is just one line of code containing the argument so there won't be any issue if it is merged to the master branch directly so that we can quickly update the module and get the correct output.

Thanks for the PR,

Can you please add a non-regression test (mentioning the original issue number) by e.g. making sure the warning isn't raised when zero_division != warn? The test should be failing on master

@Bibyutatsu I pushed a few commits to add the missing test for this PR to be able to get it merged in time for the 0.22.1 release.

Note that you issued your PR from your master branch. Next time I would rather advise to create a new branch each time your want to issue a new PR instead. This way you can track the ever evolving state of the upstream master branch in your own master branch, irrespective of the order of the merge of your future contributions.

@NicolasHug @qinhanmin2014 I just added a minimal test that check the presence or abscence of the warning based on the value of the zero_division variable. The actual values of the metrics are already properly tested in other tests for the underlying metric functions.
