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: 

開啟 competitions/cloud-cover/benchmark-tutorial.ipynb，檢查失敗的 TRAIN_FEATURES.exists() assertion 周圍的資料磁碟區設定。在一個 Hub 執行個體上重現該 notebook，並將資料磁碟區的預期內容與 DATA_DIR 定義的路徑進行比較；當文件中記載的資料可用且 assertion 通過時，工作即完成。
