I tried plenty combinations and even I found out there is few types of "Single Trip" values, but still cannot pass the answer, any idea on this? I will share my code here ========================== SELECT AVG(predicted_label) as Average_Predicted_Trip_Duration, avg(label) as Average_Truth_Trip_Duration FROM ML.PREDICT(MODEL `data.model_2`, ( SELECT duration_minutes as label, start_station_name, subscriber_type, start_time, FROM `data.trips` WHERE start_station_id = ( select start_station_id from data.trips where extract(year from start_time) = 2019 group by start_station_id order by count(trip_id) desc limit 1 ) and subscriber_type Like "%Single%" ))
