Running mypy via precommit with --install-type --non-interactive seem to silence some errors

.pre-commit-config.yaml から始め、issue に示されている 2 つの pre-commit mypy コマンドを再現します。--non-interactive を付けた場合と付けない場合の動作を比較し、その後、ipykernel/pylab/config.py、ipykernel/pylab/backend_inline.py、ipykernel/ipkernel.py で報告されたエラーを確認します。異なる診断の原因が特定され、意図された設定の動作が文書化または修正されれば完了です。

It seem to be just --install-types

I also get way more errors running mypy manually, but I think this is because of missing dependencies.
