Auto-regression model doesn't work ?

[theoeiferman]

Hey, couldn't find anything online for this error : Raise ValueError("cannot reindex from a duplicate axis")

When I am tring to fit the model to my simple dataset data_prophet this way:

model_AR.fit(data_prophet,valid_p=0.2,freq='H',epochs=100)

where

model_AR =NeuralProphet(n_forecasts=60,n_lags=60,changepoints_range=0.95,n_changepoints=100,yearly_seasonality=True,weekly_seasonality=False,daily_seasonality=False,batch_size=64,epochs=100,learning_rate=1.0)

What's wrong here ?
Thans you in advance for your help

Hi @theoeiferman
This sounds like a data format issue. Might you have an index in your dataframe?
You can try creating a fresh dataframe without an index and just 'ds' and 'y' columns.
If that does not resolve it, please share some details about your dataframe.
