error running financial_functions.py

[YoumnaAtta]

I am running into this error in financial_functions.py in
loan.TaxCreditIncentives.itc_fed_percent = agent.loc['itc_fraction_of_capex'] * 100
TypeError: error converting tuple to array: argument must be iterable

I am also encountering this error - just curious if you have found a patch. Thank you

Hi @sfk1107,
I believe this is a quirk with PySAM, but it is is fairly simple fix. You can update the line in financial functions to be:

loan.TaxCreditIncentives.itc_fed_percent = [agent.loc['itc_fraction_of_capex'] * 100]

Which will make the singular value be read as a list (iterable) instead. Let me know if that gives you any issue once implemented and I can take a second look

Thanks for your help. I implemented your fix then got a TypeError, so I added pd.to_numeric to get that resolved: pd.to_numeric([agent.loc['itc_fraction_of_capex'] * 100]) As an aside, now when I run the model, it estimates the years 2014 and 2016 then stops running and won't go beyond those years. Any idea what could be going on there? Thanks again
