Hi @Brian Head, yes it still applies if you are using
scaler_type
to scale the data, and only for RNN methods. It will still return values, but we have seen that because of the way we are scaling, we have seen some performance degradation for the predict insample. If you scale the time series before (with the core class, see this tutorial: https://nixtla.github.io/neuralforecast/examples/time_series_scaling.html ) then this warning does not apply.

Thank you again @Cristian (Nixtla). I'm now having a different issue with
predict_insample
. I started getting an error
Copy code
ValueError: could not broadcast input array from shape (48384,9) into shape (48222,9)
after making the scaling change. It still happens after switching back to what I had. I can't find anything else I've changed. Any ideas?
BTW,
cross_validation
and
fit
both work as expected. It's only a problem with the
predict_insample
.
