bug: pydantic v1 incompatability error (Py3.14 wheels)

[chamalgomes]

Noticed the following error on the CI runs, might be due to pydantic incompatibility ?

How to reproduce the behaviour

Hey, just want to add on here that spacy isn't functional on Python 3.14 because of this issue. There's a more detailed synopsis here: pydantic/pydantic#12363, but the pydantic.v1 namespace on pydantic>=2.0.0 doesn't support Python 3.14. Similarly, pydantic<2.0.0 doesn't support Python 3.14 at all.

[ghmeier]

For folks following along, Pydantic merged an update to v1 that supports 3.14: pydantic/pydantic#12636. That version of v1 should be included in pydantic v2.13 when that's released in a few weeks.

[bvolkmer]

Wouldn't this be the moment to seriously consider upgrading to Pydantic v2? As v1 will cease to be supported eventually. For 3.14 it already wasn't planned (even though it was now implemented, but with the v2 release still pending)

[chamalgomes]

@ghmeier latest Pydantic pre-release has a minor issue with version but the code is the latest and it still does not resolve the above issue. pydantic/pydantic#12852
