Data not available in benchmark-tutorial.ipynb

Working through competitions/cloud-cover/benchmark-tutorial.ipynb on a hub instance, the notebook states the data should be available in a volume but this is not the case:

---------------------------------------------------------------------------
AssertionError                            Traceback (most recent call last)
Input In [4], in <cell line: 5>()
      2 TRAIN_FEATURES = DATA_DIR / "train_features"
      3 TRAIN_LABELS = DATA_DIR / "train_labels"
----> 5 assert TRAIN_FEATURES.exists()

AssertionError: 

打开 competitions/cloud-cover/benchmark-tutorial.ipynb，检查失败的 TRAIN_FEATURES.exists() assertion 附近的数据卷设置。在一个 Hub 实例上复现该 notebook，并将数据卷的预期内容与 DATA_DIR 定义的路径进行比较；当文档中记录的数据可用且 assertion 通过时，工作即完成。
