@shiyu1994 did you use admin powers to merge this despite failing CI checks?

It looks like most CUDA CI jobs are failing.

bba92b5 has passed all the tests. And a883479 just changes a comment. And the tests failed simply because the branch is already merged.

oooo ok I see, thanks @shiyu1994

I normally would say we should wait for all of CI to run successfully before merging, but I understand that you're actively working on this part of the code right now and all other non-CUDA CI passed, so I think it was ok this time.

[shiyu1994]

@jameslamb Thanks for your kind understanding.

[jameslamb]

thank YOU for all your work on cuda_exp! really exciting to see the progress 😊
