Pydantic dependency

[andresailer]

Hi @jonas-eschle

Is the requirement for pydantic something for the runtime of zfit

zfit/requirements.txt

Line 17 in 7a2fc4d

pydantic<2.0.0 # fails with not a "subclass", won't fix soon

Or is this a testing dependency?
For the LCGstacks it would be nice if we can update pydantic.

Thanks for clarifying!

Hey thanks for bringing it up, it's unfortunately a runtime dependency, but an inconvenient one! It is however only used in the serialization.
We're working on getting it upgraded or at least having it as an optional dependency, it's a blocker otherwise.
I'll ping you if there are updates

[andresailer]

Thanks for your answer! I look forward to the update :)
We are currently trying to get python 3.11 integrated, and for that we need to update pydantic.

Out of curiosity, why exactly would you need that for Python 3.11? I assume some dependency conflicts? Pydantic 1 supports up to 3.12 at least

[andresailer]

Ahh, good point! Maybe we just too eagerly updated from the version we had, and we should just go to https://pypi.org/project/pydantic/1.10.15/.

[jonas-eschle]

That should surely work as an intermediate step, yes

I'll keep this anyway open, as we're trying to move to Pydantic 2 anyways

thanks for upgrading the LCG!

@andresailer you will need pydantic 2 if you upgrade correctionlib to v2.5.0 though.
