Since PIL is only used optionally in integration tests (with a try/except fallback), we add a mypy override to ignore missing imports for PIL modules. This fixes the Python 3.11 CI failures while maintaining type safety for the rest of the codebase. --- pyproject.toml | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/pyproject.toml b/pyproject.toml index c3263f9..28df13c 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -105,6 +105,10 @@ disallow_any_unimported = true module = "tests.*" disallow_untyped_defs = false +[[tool.mypy.overrides]] +module = "PIL.*" +ignore_missing_imports = true + # Pytest configuration moved to pytest.ini [tool.coverage.run] From 045aed04b4418334a9b4ab77676a5861b700fb36 Mon Sep 17 00:00:00 2001 From: Jonathan Rhyne Date: Wed, 25 Jun 2025 00:36:47 -0400 Subject: [PATCH 13/13] fix: disable disallow_any_unimported for tests in mypy config This prevents mypy failures when optional dependencies like PIL are imported in tests --- pyproject.toml | 1 + 1 file changed, 1 insertion(+) diff --git a/pyproject.toml b/pyproject.toml index 28df13c..bcde3cd 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -104,6 +104,7 @@ disallow_any_unimported = true [[tool.mypy.overrides]] module = "tests.*" disallow_untyped_defs = false +disallow_any_unimported = false [[tool.mypy.overrides]] module = "PIL.*"
