I try to do the certification ML Practionner but I have a problem with the data from the first question.
It is asked to exam the column "grade". After changing the type to "integer" instead of string, I begin a univariate analysis by split by school but I have no data in "grade".
I have a warning and the column grade is empty as you can see in the file attached.
I delete the project many times and download again but it's Always the same problem. After changing grade, the column is empty?
Can you help me ?
Tanks a lot.
Operating system used: DSS
I think the problem is resolved. the storage for "grade" was integer with decimal !!! I take double and it's okay.
sorry for the question but I'm new with dataiku.
