For Question 3: "Instead of using sklearn.metrics.r2_score, how you calculate the coefficient of determination (r2 score) in this script?", apparently all the options given there are incorrect. Do you mind fixing it soon? Thank you!
Hi svaishnavim! We have checked on our end and several of our staff have also given it a go. We have not been able to recreate the problem you mentioned. Could you log out and re-log in again and let us know if the problem persists? Thank you!
