[BUG] running the Leiden algorithm doesn't support oversubscription

[Lem-P]

Describe the bug While running the leiden algorithm rsc.tl.leiden(adata, key_added="leiden_res0_25", resolution=0.25 , I got a "CUDA error encountered 101 cudaErrorInvalidDevice invalid device ordinal"

Just setting rmm.reinitialize managed_memory to False resolved the issue

Expected behavior Just information for other people running into the same error

Environment details (please complete the following information):

• Environment location: Conda running in WSL2
• Linux Distro/Architecture: Ubuntu 22.04.4 LTS
• GPU Model/Driver: [RTX 3070 and driver 31.0.15.5161]
• CUDA: 12.4
• Method of Rapids install: conda

where did you get the error? That means do you get this in rsc or cugraph. Could you also please upload the full stack-trace. If you can reproduce the error just with cugraph. I think I would be amazing if you create an issue there too.

I get this in rapids_singlecell

Ok I cant reproduce the error. Can you make an issue on cugraph. This happens inside of the cugraph graph construction. They should know about this, because they might be able to fix this.
