[BUG] test_empty_slice_1d/test_empty_slice_2d fail with NumPy 2.2.1 #108
Description
Describe the bug
The same tests pass with NumPy 2.0.1 but fail with 2.2.1.
Upon a closer inspection, I noticed that somewhere in this repo NumPy has been pinned to 2.0.2, so all CI runs in this repo could not catch this test error. However, I am unable to locate where the pinning is done. It could be possible that it comes from the RAPIDS CI setup, since lots of CI infra here seem to come from RAPIDS.
Steps/Code to reproduce bug
Update NumPy to 2.2.x and rerun the tests.
Expected behavior
Test pass.
Environment details (please complete the following information):
See below.
