Hi scikit-learn team,

We’re reaching out to propose enabling CI support for the ppc64le (IBM Power) architecture in your repository, as part of a broader effort to ensure cross-platform compatibility in the scientific Python ecosystem.

We’re using a GitHub Actions (GHA)-based runner service provided and maintained by IBM to run jobs for the ppc64le architecture. This setup has already been successfully integrated into projects like:

✅ cryptography

📌 Tracking issue in NumPy

We’d now like to propose enabling the GitHub Actions app in this repository to allow running CI jobs for ppc64le directly via GitHub Actions. This would support upstream compatibility and help ensure continued support for the Power architecture in scikit-learn.

Key Benefits:
🔒 Ephemeral and secure runners, isolated per job

🛠️ Maintained by IBM, requires no setup effort from your side

🔁 Integrates with existing GitHub Actions workflows

📚 Technical documentation and usage details:

We’re happy to assist with the setup or provide any additional details the team may need.

Thanks so much!
