Maybe relevant:

https://github.com/cython/cython/commit/b37607f46b165e81f7af2b4eec2ae7f76f7717df

garfieldnate commented 2 years ago

Cython 0.29.24 fixed the issue. Is it correct to say that all that is needed is to rebuild this library with the new version?

christianbundy commented 2 years ago

I think so -- although I'd also like to see Python 3.10 added to the build matrix (https://github.com/scrapinghub/python-crfsuite/pull/131)

garfieldnate commented 2 years ago

Makes sense. I don't know anything about the CI system used here (there is an open PR that migrates it over to GH actions), but regenerating the CPP files using a new Cython version turned out to be very easy. I've opened a PR with the new files. For now, I'm just using my fork in my dependencies, specified in poetry like so:

python-crfsuite = { git = "https://github.com/garfieldnate/python-crfsuite.git", branch = "fix-python-3.10" }
christianbundy commented 2 years ago

Thanks for merging the fix @kmike! Looking forward to a new release.

chingc commented 2 years ago

Hi, I hit this problem today and judging by the comments in this ticket it appears the problem has already been fixed. It's been about a month since the last comment. Any ETA on when the fixed version will be released? Thanks!

kmike commented 2 years ago

He @christianbundy @chingc! The issue with the release is the following: we were making releases from CI; CI has been building wheels for various platforms, to simplify installation. Then, the CI got broken. I migrated tests from travis.org (which no longer works) to Github Actions, but haven't migrated the releasing and wheel building setup yet. That's why we don't have a release yet.

In the meantime it should be possible to install pythton-crfsuite from github using pip. It won't contain wheels, but with a compiler available installation should work.

chingc commented 2 years ago

@kmike Thank you for the status update!

christianbundy commented 2 years ago

Would you be open to publishing an pre-release (e.g. alpha/beta/rc) to pip? I don't need prebuilt wheels, but it'd be great to avoid depending on this GitHub repo.

chris-erickson commented 2 years ago

This works for me, python 3.10.1 in my requirements.txt (for future hair-pullers, this was required by usaddress in my case):

anyone can help me fix this error step by step ? i am a newbie and try everything i can but it not working

mlissner commented 2 years ago

Hi, I'm trying to upgrade my code to Python 3.10, but I can't because my code relies on usaddress, which relies on this package.

@kmike, you said the CI is broken. Could I help fix it somehow? I assume you're referring to the github actions? I don't see any issue explaining what's wrong with the CI, but if you or somebody else could explain, maybe I could take a look, so we could get a Python 3.10 release out the door?

Thanks in advance for this useful package!

Just use pip install -U git+https://github.com/scrapinghub/python-crfsuite.git or add python-crfsuite = { git = "https://github.com/scrapinghub/python-crfsuite.git" } to your Pipfile if you are using one.

fgregg commented 2 years ago

there is now a 3.10 compatible release on pypi
