We have decided to cherry pick our generic time series features from our generative regression branch and add it to RAMP in a separate PR. We'll also have new tests (get rid of El Nino and netcdf), and also a generic kit where we add popular time series predictors in individual submissions. Anybody using the current time series ingredients, eg https://github.com/paris-saclay-cds/ramp-workflow/blob/master/rampwf/cvs/time_series.py? Do you mind if we break El Nino (but provide a cleaner kit for time series)?
