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 1 new columns ({'id'}) and 1 missing columns ({'sales'}).

This happened while the csv dataset builder was generating data using

hf://datasets/ibnummuhammad/coal-price-data/demand-forecasting-kernels-only/test.csv (at revision 70784cf9108c4c64f408f2b89e852dffdf7d6376)

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)
