[BUG]

[salsa360]

Describe the bug When running ARIMA, I get an error message - TypeError: new() got an unexpected keyword argument 'p'.

To Reproduce model_arima = ARIMA(p=0, d=2, q=2)

model_arima.fit(train) prediction_arima = model_arima.predict(len(val))

System (please complete the following information):

• darts==0.8.1
• The system version is 3.8.13 (default, Mar 28 2022, 06:59:08) [MSC v.1916 64 bit (AMD64)]

Could you update Darts doing pip install -U darts

I updated Darts as suggested but the same issue persists even with running DARTS in Google Colab.

Could you then provide a fully self-contained code snippet to reproduce the issue, as well as the full stacktrace of the error you obtain? Are you sure the ARIMA symbol is really the Darts model and not another import?

Hi Julien,

Thanks for responding.

Attached is my ipynb file and input date file. Listed below are the error messages I am getting.

ERROR MESSAGE 1

model_arima.fit(train) prediction_arima = model_arima.predict(len(val))

series.plot(label='Actual') prediction_arima.plot(label='ARIMA Forecasting', lw=2) plt.legend() plt.show()

Thank you.
