🚀 Pull Request

Description

This PR expands on the original demonstration (a82bea0) to make Iris fully NumPy v2 compliant. Notable changes:

Expand for the text from the original demonstration:

We already know that Iris' syntax is NumPy v2 compliant, thanks to Ruff, but that does not prove that the code will all function with NumPy v2.

A vanilla Conda install of Iris does get NumPy v2, but unfortunately our full test environment does not (some of the dependencies must be pinned). So I have forced the issue by manually editing requirements/locks/py312-linux-64.lock, which does thankfully produce a working environment since none of NumPy's dependencies have changed.

The test failures show us what work we need to do for Iris to be compliant with NumPy v2. It seems to mostly be around changes in:

  • Handling of array dtypes
  • Array string representation
  • Array difference tolerances

Note to self: tests.test_ff.TestFF2PP2Cube.test_unit_pass_0 keeps flipping between expecting float32 or float64. I suspect a NumPy v2 change now means that something is no longer deterministic.

I propose that the performance changes (e.g. #6035 (comment)) are:

  • Acceptable - only a couple of minor regressions
  • Too specific to report in a What's New entry

Note to self: tests.test_ff.TestFF2PP2Cube.test_unit_pass_0 keeps flipping between expecting float32 or float64. I suspect a NumPy v2 change now means that something is no longer deterministic.
