I am getting the following assertion error: AssertionError: Wrong length for d['costs']. 20 != 1 However, I don’t understand how the length of d[‘costs’] could actually be 1. In optimize(), the code automatically appends the cost ever 100 iterations, and in model_test() the number of iterations is…

In model_test the number of iterations is set to 50, you can check it by printing the d dictionary. Someone else has solved this issue by removing the default values in optimize function.
