operands could not be broadcast together with shapes (13,) (0,) (13,)

This error message usually occurs when trying to perform an operation between two arrays with incompatible shapes. In this case, it seems like one of the arrays has a shape of (13,) while the other has a shape of (0,).

This could happen if one of the arrays is empty or has been incorrectly defined. It could also happen if you are trying to perform an operation that requires two arrays of the same shape, such as addition or multiplication.

To fix this error, you should check the shapes of both arrays and make sure they are compatible. If one of the arrays is empty, you may need to fill it with appropriate values or redefine it with the correct shape. If you are performing an operation that requires two arrays of the same shape, you may need to reshape one of the arrays to match the shape of the other.
