Had to debug an error in the SQL to make the lab work. The ABS(MOD(FARM_FINGERPRINT(CAST(CURRENT_DATE() AS STRING)), 10)) < 8 field was the issue. Since current date function would be the same for all records, it returned 9 for all records. This meant that there were no records in the training dataset! I was able to get through the lab by changing this to FlightDate (the date of the flight in the dataset), but I'm not sure if this was the intent. ABS(MOD(FARM_FINGERPRINT(CAST(FlightDate AS STRING)), 10)) < 8
