FYI, I received this warning for this code being a future error (Lecture 26)

UG[i] = U[c]

DeprecationWarning: Conversion of an array with ndim > 0 to a scalar is deprecated, and will error in future. Ensure you extract a single element from your array before performing this operation. (Deprecated NumPy 1.25.)
UG[i] = U[c]

Thanks @Suurf
To fix this, we need to explicitly specify which element from ⁠U[c] we want to assign to ⁠UG[i]. Since there is only one item in U[c], we can simply call .item() as follows:

UG[i] = U[c].item()

Thanks again,
