    Hi Victor,

    Could you please post a minimal, reproducible example? This must include how all variables and data in your code are created so that we can reproduce the error and point to the issue.

    An educated guess based on the error message: one of the terms on the "objective =" line is a scalar (a numpy.float64 type) not an array, which is required for the matrix multiplication operator "@". However, I cannot tell which term is causing the error without knowing what each object is in your python code.
