Enable Python 3.13 #85
Conversation
Tested working with `kokoro -t Hello -o test.wav`. This is needed for Ubuntu 25.04.

Any idea when this will be merged in? |

@hexgrad This misaki PR should be merged so that the identically-named kokoro PR you merged can start having effect. |

Blis seems to be not yet ready for Py3.13 |
|
That cython-blis PR is not evidence that "Blis seems to be not yet ready for Py3.13". The last part that "Changes accepted Python versions to <3.15" merely enables Python 3.13 testing. Unlike this PR, cython-blis already had 3.13 enabled. The first half of that cython-blis PR adds "free-threading support". According to https://docs.python.org/3/howto/free-threading-python.html , "The free-threaded mode is experimental and work is ongoing to improve it: expect some bugs and a substantial single-threaded performance hit." Most machine learning people aren't enabling it in production, if not, at all. They are using the "the default GIL-enabled build". Even if I wanted to use free-threading, I couldn't find the build for Ubuntu, or upstream in Debian. Most importantly, since cython-blis is declaring incompatibility with free-threading, so my this PR will allow installation on normal Python 3.13, while I think the cython-blis dependency will block installation when using the experimental option. |

Why does the Python 3.13 test fail in |
|
That is because something is pinning Blis to 0.7: https://github.com/cclauss/misaki/actions/runs/17343241531/job/49239886842#step:5:237 I will send a PR here fixing this via spaCy in a few minutes. |
spaCy 4 hasn't been released. 4.0.0.dev{1,2} have been yanked,
questioning the stability. More importantly, 4.0.0.dev3 was published
2024-04-22 while the normal 3.8.7 is newer, being published 2025-05-23,
a whole year later. The outdated 2024 spaCy depends on an outdated
thinc, which depends on an outdated blis whose build fails on Python
3.13.
I fixed this by restricting spaCy to stable 3.x versions. The spaCy 4
apparently wasn't even being used in the final installation that Kokoro
sees, somehow only appearing in a misconfigured build step.
