Task 2 is not working. Kindly help me!!! Pls help with appropriate code -- Evaluate the performance of the customer_classification_model SELECT * FROM ML.EVALUATE(MODEL `ecommerce.customer_classification_model`, ( SELECT * EXCEPT(fullVisitorId) FROM # features for evaluation (SELECT fullVisitorId, IFNULL(totals.bounces, 0) AS bounces, IFNULL(totals.timeOnSite, 0) AS time_on_site FROM `data-to-insights.ecommerce.web_analytics` WHERE totals.newVisits = 1 AND date > '20170430') -- evaluate on data after the training period JOIN (SELECT fullvisitorid, IF(COUNTIF(totals.transactions > 0 AND totals.newVisits IS NULL) > 0, 1, 0) AS will_buy_on_return_visit FROM `data-to-insights.ecommerce.web_analytics` GROUP BY fullvisitorid) USING (fullVisitorId) ));
