Note the datetime column is in datetimeformat , even then it throws error. Could you please help me with the resolution

Sorry this issue still persists. Please consider it open
Machine_learning_Assignment (1).zip
Attached is the sample notebook
Hi @plaban1981 👍
Thanks for the detailed notebook. yes I found the bug and fixed it, you should upgrade your auto-ts version like this:
pip install auto-ts --upgrade
and run it.
All the best!

Thanks a lot for the prompt resolution. It surely does executes for Prophet now . Much Appreciated.

Hi @plaban1981 👍
I found that you should set seasonality = False and run ARIMA first. Then try it setting as True.
