Example of Cython file not compiling:
Error compiling Cython file:

That's very interesting. At the moment, it's challenging to setup the same environment as yours. May I suggest the following options:
- Use Conda to install Cornac.
- Reinstall C++ compiler using Homebrew with
brew install gcc | brew link gcc, then try to install Cornac again usingpip.
Let us know if it resolves your issue.
Hello,
I finally managed to install cornac using conda, but I only got version 1.7.1. How do I upgrade it to 2.1.0?@monuoha could you double check if it's installed from the conda-forge channel?
conda install cornac -c conda-forge
The above command is what I used to install conda.
You can check which version and which channel the package is pull from as shown in the image below:
How do I access that image, I exited out of the terminal window right after cornac was installed.
you'll see it when you run the command
conda install cornac -c conda-forgeI already ran the command, and this is what it showed me:
Collecting package metadata (current_repodata.json): - WARNING conda.models.version:get_matcher(538): Using .* with relational operator is superfluous and deprecated and will be removed in a future version of conda. Your spec was 1.7.1.*, but conda is ignoring the .* and treating it as 1.7.1 done Solving environment: done ==> WARNING: A newer version of conda exists. <== current version: 4.14.0 latest version: 24.3.0 Please update conda by running $ conda update -n base -c conda-forge conda # All requested packages already installed.

Description
Whenever I try to install cornac, several Cython files refuse to compile.
In which platform does it happen?
macOS 12.7.3
How do we replicate the issue?
Run pip install cornac in Terminal
Expected behavior (i.e. solution)
The terminal command should be able to install the cornac package with no problems.
