hey @tibeler. thanks for letting us know about this issue. could you please try adding n_windows=None to cross_validation?

[tibeler]

i am sorry ,now it appears to have another problem. when i use nf.cross_validation(df, n_window = 4,step_size = horizon), it turns out to be : TypeError: TimeSeriesDataModule.init() got an unexpected keyword argument 'n_window'. thank you !
