Same issue as here: #37729 (comment)

[dwong2708]

I removed this code to keep only the bump changes, but I noticed the CI is failing due to the requirements. Do I need to run make compile-requirements to fix it? I ran it earlier, and it removed this code from the file. @ormsbee

@dwong2708: I guess so. Yes, please run make compile-requirements and see what happens. Thank you.
