LGTM. Feel free to merge once you released the new version.

Looks good from my side, too, if all the tests are passing. 23.04 RAPIDS release should be on April 12th, so this will stay blocked for at least another 2 weeks.

Hi @rusty1s, we have a bit of a compatibility issue here among RAPIDS packages, due to the the different release cadence of Rapids and PyG. The upcoming cugraph 23.04 release is pinned to PyG 2.3.0, however, PyG 2.3.0 was release with cugraph-ops 23.02 (since we did not want to break users at the time).

Is there a chance that we can have a minor release that incorporates this PR? Apologies for the late communication, we will plan this ahead in future releases.

I think this is possible. Let's discuss in person today.

@rusty1s I repurpose this PR to support both 23.02 and 23.04 APIs, feel free to check again. Thanks!

Hey @rusty1s , just want to follow up with the minor release request. Do we have any blockers? Thanks!

[rusty1s]

No blockers, let me create 2.3.1 tomorrow :)
