While running pip install faststylometry, I get this error (linux OS, python 3.12.3):

Hi @Francois-Rolland

thanks so much for the feedback and please forgive my late reply.

I have now upgraded the library to 1.0.15. It works with Python 3.12 but you need to downgrade Numpy.

You need Python 3.12 or later

This is inconvenient because Google Colab runs on 3.11 by default. So anyone running the Colab script needs to work out how to upgrade Python within Colab to get this library to work.

Then you can install with

pip install faststylometry==1.0.15
pip install numpy==1.26.4

The second command is to downgrade Numpy. I tried to get the library to build so that it runs with Numpy 2.x but I cannot see how to do that. This is still an open issue if anyone can see how to make the Pypi package build with upgraded Numpy.

For anyone coming across this issue

Please can you check the pyproject.toml and .github scripts to see how you can make this package build, so that it runs out of the box with Numpy 2.x?
