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 5 new columns ({'nan', 'stage', 'total', 'asset', 'pct_nan'}) and 29 missing columns ({'return_sse_short', 'return_btc_smooth', 'return_sp500_short', 'return_sp500_long', 'date', 'return_btc_medium', 'return_oil_short', 'return_sse_smooth', 'return_sse_long', 'return_sp500_smooth', 'return_sse_medium', 'return_vnindex_short', 'return_vnindex_long', 'return_vix_smooth', 'return_vix_long', 'return_btc_short', 'return_vix_short', 'return_gold_medium', 'return_oil_medium', 'return_gold_long', 'return_vnindex_medium', 'return_oil_smooth', 'return_vnindex_smooth', 'return_gold_short', 'return_sp500_medium', 'return_btc_long', 'return_vix_medium', 'return_gold_smooth', 'return_oil_long'}).
