J08nY · 2025-01-16T11:18:08Z

Description

Fixes the build on Python 3.13 (with Cython 3). Fixes #926 and fixes #947.

Types of change

Removal of Cython version restriction and a small fix.

It would also be neat to check the Cython 3.1 alpha release or Cython's master branch against free-threaded 3.13.

See https://py-free-threading.github.io for more info about supporting free-threaded Python in native code.

J08nY · 2025-02-02T11:26:42Z

Any progress on getting this in and cutting a new release? Python 3.13 is now 4 months old.

I would be willing to test this in conda-forge (where we run the test suite anyway), but thinc depends on srsly, confection & wasabi, so those need to be solved first.

Xref conda-forge/srsly-feedstock#53

I would be willing to test this in conda-forge (where we run the test suite anyway), but thinc depends on srsly, confection & wasabi, so those need to be solved first.

It seems that all of srsly, confection & wasabi now install under Python 3.13. Atleast in my environment.

I am getting lots of warnings while running tests under 3.13:

It will be disallowed in Python 3.15.
    return cast(Any, type_)._evaluate(globalns, localns, recursive_guard=set())

Also some errors:

which expand out to this, and are clearly connected to the warning:

Seems to be an upstream pydantic issue: pydantic/pydantic#9613

Pinging this. Could anyone have a look, fix the failing test and merge? It is blocking a lot of people depending on spacy.

salty-horse · 2025-02-12T08:09:39Z

requirements.txt should also be updated, since it's referenced in the README.

If no-one responds in a few more weeks, maybe email Explosion.

For 3.13, we'd also need to lift the cap here

thinc/setup.cfg

Line 37 in 256e403

blis>=1.0.0,<1.1.0

because we only have 3.13 builds for blis>=1.1 (though it's technically possible to backport this to 1.0, that makes no sense IMO in terms of policy).

I can confirm that this PR allows to build thinc on Arch Linux with Python 3.13

Does this fix all of the test failures? I haven't had a chance to try.

davispuh · 2025-03-07T17:08:35Z

It only fixes so that tests itself run.

There are some test failures but I'm not sure if they're due Python 3.13 as they might be because of some other reason.

Thanks for attention on this. We've had a size restriction on PyPi that prevented releases on spaCy, and there's issues associated with Python 3.13 to do with the Pydantic usage for validation. I'm working on the update now.

We need to target the 8.3.x branch. That's the one spaCy uses.

I've been streaming some spaCy and ecosystem development to increase transparency, so you can see some of the issues around Pydantic in this stream: https://www.youtube.com/watch?v=TTEWWJ2PmZQ&list=PLBmcuObd5An5_iAxNYLJa_xWmNzsYce8c&index=1&t=2882s . I've had to work on a consulting project the last couple of weeks so I had to pause work on this, but I'm back on it now.

Unknownuserfrommars · 2025-04-04T08:58:26Z

Guys any news on this? Lots of packages are depending on spaCy and it can't update to support for Py 3.13.

Support Cython 3 (and also Python 3.13).
