From 7dcf79b8f8bc0ddf756963548314a5f59e34e90f Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Mon, 4 Sep 2023 17:47:12 +0100 Subject: python3-numpy: Attempt to fix reproducibility issue We've seen reproducibility failures where it appears an extra -O3 compiler flag ends up in the multiarray library compilation. This can only really have come through extra_info for BLASS support since it only affects just this library. Rather than try and track down exactly where this came from in a rabbit warren of code, just disable this since we don't have any of the dependencies anyway.
