required dependency on importlib_resources missing

まず tensorflow-datasets の依存関係メタデータと、importlib_resources に到達するデータセット読み込みパスを調査します。不足しているパッケージをインストールする前後の Python 3.12 環境で、失敗を再現します。新しい環境で、キャッシュされていないデータセットを ModuleNotFoundError なしでダウンロードできれば完了です。

/!\ PLEASE INCLUDE THE FULL STACKTRACE AND CODE SNIPPET

Short description
Description of the bug.

Our downstream project depends on tfds and while we're in the process of patching in our repo, the better answer would be for you to fix it directly in yours.

Simply adding a dependency for higher python versions than 3.9 for importlib_resources should be sufficient.

Our repo is https://github.com/trueagi-io/FabricPC and here's the stacktrace.

Environment information

• Operating System: ubuntu 24

• Python version: 3.12.3

• tensorflow-datasets/tfds-nightly version: tfds_nightly-4.9.9.dev202510250044-py3-none-any.whl

• tensorflow/tf-nightly version:

• Does the issue still exists with the last tfds-nightly package (pip install --upgrade tfds-nightly) ?
  yes it does

Reproduction instructions

In a python3.12 (and possibly other >3.9) virtual environment on a machine where a dataset has not yet been downloaded, try to use tfds to fetch the dataset and you'll get an error.

<put a code snippet, a link to a gist or a colab here>

If you share a colab, make sure to update the permissions to share it.

Link to logs
If applicable, <link to gist with logs, stack trace>

Expected behavior
What you expected to happen.

I expected the dataset to download and instead got the above stacktrace.

After pip install importlib_resources the problem disappears.
