Let's examine the uploaded dataset file to identify any issues related to <hint>. Upon reviewing the file, the following potential issues were found:

1. The script has several TODO comments indicating unfinished tasks:
   - In the `ADULT` class:
     - Set up version information (TODO: Set up version).
     - Implement logic to download data and define splits (TODO: Downloads the data and defines the splits).
     - Implement logic to yield key and example tuples from the dataset (TODO: Yields (key, example) tuples from the dataset).

These tasks need completion for the script to work correctly and provide its intended functionality.

Summary of potential issues:

<issue>
{
    "issue": "Unfinished tasks in the script",
    "evidence": "TODO comments found in the script indicating unfinished tasks. These include: Set up version, Downloads the data and defines the splits, Yields (key, example) tuples from the dataset.",
    "description": "The script contains TODO comments for unfinished tasks that need completion. These tasks include setting up the version, implementing data download and split logic, and yielding key and example tuples. Addressing these tasks is crucial for the script's proper functioning.",
}
</issue>
