Failed to install through pip install lap

[vrij]

Hi, thank you for providing this project! I was excited to see that it supports matrices with differing cardinalities. Though the installation sadly didn't work. Is there a way to resolve this?

My machine runs OS X Monterey 12.5 on an intel processor. Here are the logs:

~ % pip3 install lap Collecting lap Using cached lap-0.4.0.tar.gz (1.5 MB) Preparing metadata (setup.py) ... done Installing collected packages: lap DEPRECATION: lap is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option.

note: This error originates from a subprocess, and is likely not a problem with pip. error: legacy-install-failure

Thanks in advance

i got the same problem here, but i used conda instead and that solve my problem. Try this :: conda install pip :: its work for me. hope this will help ur probs

[Zoe-Wan]

i got the same problem here! And I can't find the solution, maybe I'll try conda later...

[coder111111]

I can confirm I can reproduce the same problem on Debian/Sid with Python 3.11.2.

[douo]

I believe that updating to a newer version of Cython should resolve this issue. The problem is caused by a change in Python 3.11:

The non-limited API files cellobject.h, classobject.h, code.h, context.h, funcobject.h, genobject.h and longintrepr.h have been moved to the Include/cpython directory.

Newer versions of Cython add a version check to this include, as shown below:

The upper version 0.4.0 was downloaded from PyPI. The lower is 0.4.0 was built using Cython 0.29.30.

I don’t think _lapjv.cpp should be included in the RELEASE package.

Got sick of this issue so here you go! Just copy the two sub folders lap and lap dist into your site packages folder https://github.com/Adnedvid/Lap-pkg-for-YOLO.git

[Yingrjimsch]

I'm getting the same error did someone fix it? Updating Cython did not help in my case

[Adnedvid]

Did you try copying the package directly like I mentioned above? It has worked for me on 4 different windows machines the past 2 months.

[Ounceleopard]

Try: pip install lapx

Try: pip install lapx

I'm also using Mac Monterey on intel processor. THis works very well - thank you

This is what I've been doing for the past year. Keeping a copy of lap as a backup. As far as I'm aware this approach works on Mac, Linux and Windows.

Interestingly enough, pip is able to install lap on my MacBook with Python 3.9.13. Trying to install it on Windows with the same version of Python and pip results in failure.

You can downgrade the Python from 3.11 to version 3.8.19. It works for me.
