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 23 new columns ({'mean_seed_ir', 'mean_best_sharpe', 'n_seeds', 'mean_best_aer', 'year', 'mean_seed_sharpe', 'mean_best_performance_return', 'mean_best_ic', 'mean_best_winrate', 'n_valid', 'mean_best_ir', 'vr_global', 'mean_seed_winrate', 'mean_seed_ic', 'mean_seed_performance_return', 'mean_seed_aer', 'n_calls', 'pass_at_3', 'vr_seed_mean', 'market_regime', 'mean_seed_mdd', 'mean_best_mdd', 'pass_at_5'}) and 2 missing columns ({'{', '__index_level_0__'}).

This happened while the csv dataset builder was generating data using
