`pip install lightfm` fails

Thanks for opening an issue!

Please include as much detail as possible: what does your dataset look like, what hyperparameters you are using (and have you tried other ones?).

When including code snippets, make sure you use appropriate code formatting using backtics. Have a look at the markdown reference for details: https://guides.github.com/features/mastering-markdown/.

When running pip install lightfm, this long error is printed. I have Visual Studio Build Tools 2022 v17.2.1 installed, despite the error suggesting I don’t.

I got the same issue using Windows 10, pip and Python 3.10. I tested using Python 3.7 and conda: conda install -c conda-forge lightfm

That worked for me, though I know this doesn’t address the specific issue.

[yuzhay]

I am also facing this issue. Any solutions for it yet?

I think you need to run python setup.py cythonize to regenerate *.c files for python 3.10.
