feat: Upgrade pydantic to v2

[adrijanik]

Overview

Hi team,

Do you have any plans to upgrade pydantic to v2 from v1.8.2? Is there maybe any branch that I could use if such transition is happening? It becomes a problem when you want to use opentrons library in a project where packages dependencies requires pydantic v2. I couldn't find any issue that address that.

Thanks!

Implementation details

I haven't tested that, but this could be a simple fix by using v1 apis from within v2 version, see below:
from pydantic.v1 import BaseModel

There is also a helper package bump-pydantic which may help with that. Here is also a migration guide.

Design

No response

Acceptance criteria

Lift the dependency from pydantic 1.8.2 to pydantic >=2.

Yeah, we definitely want to upgrade Pydantic. (Internal reference: RSS-227)

Unfortunately we haven't started that work yet, so there's no branch you could use. We don't have a timeline for it, since we're focusing on the new Opentrons Flex.

There is also a helper package bump-pydantic which may help with that. Here is also a migration guide.

This is helpful. Thank you!

Hello @SyntaxColoring is there any proposed plan for this?
You could even use the new namespace pydantic.v1

Sorry for the lack of updates here. Yes, we're working on this in PR #14871. It's not our first priority, though, so I can't promise it will be completed soon.

please please please prioritize this. Pydantic should have fixed many import perf issues. It's a major pain that we can't easily interoperate between core models in parts of our codebase.
