The matplotlib 3.10.9 -> 3.11.0 bump (336bff1) removed the private matplotlib.style.core submodule. preliz <=0.26.0 imports it at module load, so `import preliz` raised AttributeError during pytest collection and aborted the whole test-python job (CI run 27759402631). preliz 0.27.0 ships the fix (arviz-devs/preliz#727). Pin the floor in both environment.yml and pyproject.toml so CI and the package metadata require the fixed release. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Problem
CI run 27759402631 failed in the
test-pythonjob.pytestaborted during collection (exit code 2):Because collection was interrupted, none of the other 128 tests ran.
Root cause
A dependency-version collision triggered by a Dependabot bump:
matplotlib.style.coresubmodule.prelizwas unpinned, so CI installed 0.26.0, which still importsmatplotlib.style.coreat module load — hence theAttributeErroronimport preliz.The run was unlucky on timing: preliz 0.27.0 — which ships the fix (arviz-devs/preliz#727, "Fix import failure on matplotlib 3.11") — was published ~50 minutes after CI executed pytest.
Fix
Pin the floor to
preliz>=0.27.0in bothenvironment.yml(used by CI) andsrc/python/pyproject.toml(package metadata), so the fixed release is required and a cached/olderprelizcannot regress.🤖 Generated with Claude Code
