How to place constraints if my individual is a list of lists?

[Franco-CG]

When my problem was a list I had no problem definig g1 as:
g0= (x[1] + 1) + 1*np.sin(x[0]) + 1*np.cos(x[1]) + 1*np.cos(x[0]) + 1*np.cos(6*np.sqrt(x[1]**2 + x[0]**2)) + 1*np.sin(1*np.sqrt(x[1]**2 + x[0]**2))
g1=-g0

So since my individual is now a list of list I thorugh of:

        constr=([])
        for i in range(len(Rpath)):
          gi=(Rpath[i][1] + 1) + 1*np.sin(Rpath[i][0]) + 1*np.cos(Rpath[i][1]) + 1*np.cos(Rpath[i][0]) + 1*np.cos(6*np.sqrt(Rpath[i][1]**2 + Rpath[i][0]**2)) + 1*np.sin(1*np.sqrt(Rpath[i][1]**2 + Rpath[i][0]**2))
          constr.append(gi)
        g1=[ -x for x in constr]

but then I get the error:
Exception: ('Problem Error: G can not be set, expected shape (40, 1) but provided (40, 1, 38)', ValueError('cannot reshape array of size 1520 into shape (40,1)'))

my individual in this case was of len 38

It says that you got the dimensions wrong. It looks like you have a population size of 40 with one constraint, so make sure you set out["G"] to a list with 40 values.

Thank you for your time. Yes, but I believe my population is 38, I may be wrong (the size is random), but that is what I see when I print the values obtained by my f1.

I found this:
#154

I do something similar to this, so I believe my main problem is I dont know to write constraints when is a list of lists.

Check out the getting started guide: https://pymoo.org/getting_started/part_2.html
The problem there has also two constraints.
