Pull request overview
This PR updates Cornac’s built-in MovieLens dataset downloader to use a new mirror (static.preferred.ai) because the original GroupLens file-hosting domain is unavailable, ensuring cornac.datasets.movielens.load_feedback() can still fetch data.
Changes:
- Switched MovieLens (100K/1M/10M/20M) download URLs from
files.grouplens.orgtostatic.preferred.ai.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.
