You are probably using the old version. Please update the SDK version, and the example should work fine.

So it is not is /main yet?

I didn't understand it. It has been quite some time since set_logger_provider moved to api (opentelemetry) package.

Do you suggest I close the PR as fixed/not-required?

Yes, this change is invalid. The example works with any version >= 1.15
