LGTM.com - false positive when using imports with TYPE_CHECKING

[david-zwicker]

Description of the false positive

lgtm complains that a "Module is imported more than once" in my python code, but the first import ist protected by "if TYPE_CHECKING:", which is required for mypy type checking to work properly. I think lgtm should simply ignore imports that are under TYPE_CHECKING.

URL to the alert on the project page on LGTM.com

Here is the concrete error:

Hi @david-zwicker, thanks for reporting this 👍 I agree that your use-case is reasonable, and we probably shouldn't give a alert 😊

We're currently busy reworking large parts of the Python QL libraries, so I can't make any promises on when we'll be able to look into solving this one, but we'll keep it in our backlog 😊

Hi @RasmusWL we ran into this with

https://github.com/bluesky/ophyd-async/

it's still creating this error, we'd like to be able to turn this off too
