Hi @KumoLiu this is the solution I think for getting the tests running again using CPU runners. One issue that we'll find is notebooks will have to run under CPU, some will be very slow as a result plus many in the repo which were tested with GPU cannot be retested now. We can make this change now to put through the PRs we have waiting, or we can change branch rules to allow repo owners to circumvent stuck tests. Thoughts?

Hi @ericspod, yes. we can merge this one now to put through the PRs we have waiting and also let me change the premerge-notebools as a not "required" check, then if there are some tests must be runned on the GPU, the PR will not stuck as well. What do you think?

Sounds good, let's get PRs through but run tests where as much as we can for now.
