Some issues 1.Non-tuple sequence and 2.NonType object has no attribute get_values

AttributeError: 'NoneType' object has no attribute 'get_values'

I am getting the above errors when running the code.

1. Can someone help my getting this running? This tuple FutureWarning at the beginning seem to not affect the result. How can i avoid this error in the code?
2. why do get 'NoneType' object has no attribute 'get_values'?

Would appreciate any help to get this running. Thank you
