[GitHub] [arrow] assignUser commented on issue #34277: [Python] pyarrow does not disable SIMD CPU optimizations when set to do so.

   The issue I see above is that you try to build pyarrow from main (12.0.0) with the 11.0.0 C++ libarrow which is likely the cause for the issues due to changes on main that diverged from the 11.0.0 library thus being incompatible. 
   
   Regarding the SIMD level you will have to build C++ libarrow from source as well for the switch to work **but** as you mentioned popcnt is required regardless of SIMD level which means that the fix for this would be #23013
