Running SummarizeWithin against "memory" datasets

Question

I have a script that runs SummarizeWithin() as a step in the analysis process. If I pass it paths to feature classes within an on-disk gdb for the input and output data it runs fine, but if I try to use "memory" datasets ("memory/in_points" and "memory/out_hexes"), it fails with "ERROR 000187: Only supports Geodatabase tables and feature classes".

Does SummarizeWithin() not work with "memory" datasets?

I see this is a 4yo post, but this still persists. SummarizeWithin does support memory dataset, but you have to use in_memory, which is a legacy memory-based workspace for ArcMap, and anything written to in_memory can't actually be added to a map. It will first be converted to a file GDB dataset, and then added. This doc explains the memory workspace. Definitely frustrating, as I am encountering it, too.

I was using memory to avoid having to clean up a bunch of intermediate files, but I've built a workaround with a temporary GDB that I can nuke when I'm finished. I'll stick with that until I have time to troubleshoot more. Thanks for the suggestions!

The only thing you might try is MakeTable in memory first, then use it.

I rarely use since I dont find it speeds anything up much
