Hi, I want to share that the imputed features in /output folder in the team project directory. dt_feat_calc_design_imputed_061024.qs is the file name, and it requires qs package to read. Please note that zero variance features were already excluded, so you might want to adjust your base learner codes on doing that. Please feel free to ask me any questions. Thank you.
