The dataset generation failed because of a cast error
Error code: DatasetGenerationCastError
Exception: DatasetGenerationCastError
Message: An error occurred while generating the dataset
All the data files must have the same columns, but at some point there are 4 new columns ({'COL3', 'COL1', 'COL2', 'COL4'}) and 3 missing columns ({'B', 'C', 'A'}).
This happened while the csv dataset builder was generating data using
hf://datasets/xiexueyan/testDataset/test2.csv (at revision 450694ddea47f41812a3e30aa0539a08bfd4296d)
Please either edit the data files to have matching columns, or separate them into different configurations (see docs at https://hf.co/docs/hub/datasets-manual-configuration#multiple-configurations)
