Description

Tests and Documentation

[romanlutz]

Looks like it's failing right now. There may be a few dependencies that aren't yet 3.14 compatible, of course.

[cclauss]

Yes. The blockers I see so far are:

• https://github.com/explosion/cython-blis fails to build explosion/spaCy#13870
• Python 3.14 support for PyTorch pytorch/pytorch#156856

Are there others?

[romanlutz]

Yes. The blockers I see so far are:

• https://github.com/explosion/cython-blis fails to build explosion/spaCy#13870
• Python 3.14 support for PyTorch pytorch/pytorch#156856

Are there others?

Agreed. I'm checking to see what pulls in spaCy anyway since that's a decent-sized dependency we don't use (I think)
Spacy is part of a recent extra addition.

[romanlutz]

Heads up I'll leave this open until everything works fine in 3.14 and 3.14t because people expect things to work.

[romanlutz]

I'm about to remove semantic-kernel in #1005 but the others are all important.

@cclauss are you still interested in continuing with this? No pressure, just wanted to check in since it's been a while since we checked in on this.
