Motivation for features / changes
Nightlies are failing due to new numpy release(one example: https://github.com/tensorflow/tensorboard/actions/runs/9546526095/job/26309613783)
See #6869 for context.
Technical description of changes
The new numpy replaced np.string_ with np.bytes_ and np.unicode_ with np.str_
Screenshots of UI changes (or N/A)
Detailed steps to verify changes work correctly (as executed by you)
I ran tests that were failing and they passed.
Alternate designs / implementations considered (or N/A)
Locking numpy version < 2 was considered. However, this will eventually get us very out of date and should be avoided.
