Error with temp_fft = sp.fftpack.fft(temp) when run in Jupyter Notebook

[armarvin]

Hello, the code does not function for me when run in Jupyter Notebook. I replaced to_datetime with to_pydatetime. That fixed one error but now I am getting an error with temp_fft = sp.fftpack.fft(temp) it is throwing the error AttributeError: 'Series' object has no attribute 'flags'

I have updated Conda and scipy to the latest available and the error persists.
Thank you
