datasets.data_files.EmptyDatasetError: The directory at wikisql doesn't contain any data files
Fixed. Please close.
### Describe the bug

From these lines:

from datasets import list_datasets, load_dataset
dataset = load_dataset("wikisql","binary")

I get error message:
datasets.data_files.EmptyDatasetError: The directory at wikisql doesn't contain any data files

And yet the 'wikisql' is reported to exist via the list_datasets(). 

Any help appreciated.
