Hi, 

I am training a logistic regression in the doctor, however after training and scoring of the model (according to the logs) I have a memory error. I think this error is due to the computation of features to explain the model, is it possible to chose not to compute these features ?

Hey Mouch Mouch,

Good to see you. Updating DSS to the latest version should solve the issue!
