I’ve used the Hint’s suggestion, but it didn’t help, still getting the same error:

hi @serko

Go through these thread comments and see if it helps you

Solution 2

Solution 3

Please read each post comments carefully and with your codes, which help you to compare and decide your codes.

“+ 1” helped from

for the first code line where randomly sample the sub-volume, You are suppose to add + 1 to all the samples which you have not done according to instructions provided before the grade cell.

Thanks!
