how to call the another function to evaluate the objective function

[LaksE91]

Hi, I defined my objective function in another file and called my objective function in main()

I'm getting an error,

File "C:\Anaconda2\lib\site-packages\platypus_opt-1.0.2-py2.7.egg\platypus\core.py", line 1010, in unique if not id in unique_ids:

TypeError: unhashable type: 'numpy.ndarray'

Please find the code, I don't know where I made mistake

def main(x): return modelrun(x[0],x[1],x[2])

problem = Problem(3, 2)

x1 = Real(0.014,0.16) x2 = Real(0.06,0.30) x3 = Real(50,100) problem.types[:] = [x1,x2,x3] problem.function = main algorithm = NSGAII(problem) algorithm.run(10000)

This is just an educated guess, but I believe modelrun(...) is returning the type numpy.ndarray. I would recommend using https://docs.scipy.org/doc/numpy/reference/generated/numpy.ndarray.tolist.html to convert the return value from numpy.ndarray to a python list, e.g.:

def main(x):
    return modelrun(x[0], x[1], x[2]).tolist()

Thank you for your reply. It works.
