[bug] dataset path: rotten_tomatoes → cornell-movie-review-data/rotten_tomatoes in data_utils.py #179

Where

• Phase / lesson: Phase 0 · 09-data-management
• File / URL: phases/00-setup-and-tooling/09-data-management/code/data_utils.py

What's wrong

The main demo block uses "rotten_tomatoes" as the dataset path, which fails to load with the current datasets library. The correct Hugging Face identifier is "cornell-movie-review-data/rotten_tomatoes". This breaks the setup script for anyone running it fresh.

Reproduce

1. Clone repo
2. Install python as shown in phases/00-setup-and-tooling/01-dev-environment/docs/en.md
3. Activate venv if not activated already
4. Run phases/00-setup-and-tooling/09-data-management/code/data_utils.py

Environment

• OS: Fedora Linux 42 (WSL) x86_64
• Python / Node / other runtime version: Python 3.13.13
• How you ran it (local, Colab, Docker, etc.): local

Screenshot or logs

Proposed fix

Update the dataset path from "rotten_tomatoes" to "cornell-movie-review-data/rotten_tomatoes" in the main block. I've tested this locally and it resolves the issue. PR coming next.
