From tscv import gapkfold
WebThis cross-validation object is a variation of KFold . In the kth split, it returns first k folds as train set and the (k+1)th fold as test set. Note that unlike standard cross-validation methods, successive training sets are supersets of those that come before them. Read more in the User Guide. New in version 0.18.
