Validate automatic fold counts before KFold.
When the datalist has no folds or validation items, validate 2 <= num_fold <= len(datalist["training"]) before constructing KFold. Otherwise, invalid values fail before AutoRunner.set_num_fold() runs. Add tests for both boundaries.
Proposed fix
else:
num_fold = int(self.data_src_cfg.get("num_fold", 5))
+ if not 2 <= num_fold <= len(datalist["training"]):
+ raise ValueError(
+ "num_fold must be at least 2 and no greater than the number of training items "
+ "when AutoRunner generates folds."
