mypy fails due to "unused-ignore"

[xaellison]

Checks

• I have checked that this issue has not already been reported.
• I have confirmed this bug exists on the latest version of Polars.

Reproducible example

error occurs simply for:

import polars

Here's output from my terminal showing my virtual env, a trivial .py, and running mypy on that trivial file

Issue description

mypy fails on any code that imports polars. I want to incorporate polars into an existing project that uses mypy, but cannot due to this issue.

Expected behavior

mypy does not fail for importing polars :)

FYI: we run mypy on the codebase on every commit, and it doesn't fail ;)

I suspect you just need to update to a more recent mypy than 1.0.0 🤔

You need to update your environment. We test against mypy. I will close this as there isn't any action here for us.
