Thank you for opening this issue, we will look into it.

[microsoft-github-policy-service]

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @mbifeld, @FumingZhang, @andyliuliming.

[luckeyca]

same problem happens for the azure devops extension as well. On developer forum, it says it was fixed, but it's NOT as I am still getting it today. See the details here: https://developercommunity.visualstudio.com/t/Azure-DevOps-Extension-reports-pkg_resou/10919558. from the source code, I can still see pkg_resources is referenced everywhere which all need to be replaced to fix this issue all at once.

@yonzhan This is all over the place, not just the AKS extension: https://github.com/search?q=repo%3AAzure%2Fazure-cli-extensions%20__import__(%27pkg_resources%27)&type=code
