Not able to download or load certain data

Hi, I have some issue downloading the data.

Here, I followed the colab [notebook](https://github.com/google-deepmind/open_x_embodiment/blob/main/colabs/Open_X_Embodiment_Datasets.ipynb) to load the data, yet getting some errors in the notebook.

```py
for dataset_name in tqdm.tqdm(DATASET_NAMES):
_ = tfds.load(dataset_name, data_dir=DOWNLOAD_DIR)
```

Then, i just follow the readme to directly download the data using `gsutil`
```
gsutil -m cp -r gs://gdm-robotics-open-x-embodiment/{dataset_name} ~/tensorflow_datasets/
```

This mostly gives me empty data. Changing the bucket dir path to `gs://gresearch/robotics/` works.
