TypeError: only length-1 arrays can be converted to Python scalars
Hi All,
I will not paste my code here as it is extremely long, but I have included a snippet where the error is appearing.

Can anyone provide any advice as to what "TypeError: only length-1 arrays can be converted to Python scalars" is referring to?
