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 ({'Feature Completion Time (days)'}) and 1 missing columns ({'Feature Completion Time'}).
This happened while the csv dataset builder was generating data using
hf://datasets/naushadnizarali/developer-stats/developer-stats.csv (at revision 0bc7aefe8dfb18ea2aeb9b01795f8f4bd390a17a)
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)
