>> model = sm.tsa.arima_model.ARIMA
AttributeError: 'module' object has no attribute 'arima_model'
>> import statsmodels as sm
>> model = sm.tsa.arima_model.ARIMA  ## works fine now
What is expected:

The import should work in the very first line.




    

What happened:

To be able to function properly, the import required importing statsmodels.api then overwriting that with importing statsmodels to finally work.
