Try bumping gpy

Issue #, if available: n/a

Description of changes: GPy caught up with numpy>2, let's update!

By far the most common, and the most annoying, error is this:

TypeError: only 0-dimensional arrays can be converted to Python scalars

basically all places that were implicitly converting single valued arrays [1] or even [[1]] to 1 now have to explicitly extract the float
