Issues with Numba in AGE-MOEA

[oliverweissl]

I get the following error when using AGE-MOEA:

TypingError: Failed in nopython mode pipeline (step: nopython frontend)
Invalid use of type(CPUDispatcher(<function point_2_line_distance at 0x735c3d5b7a60>)) with parameters (array(float64, 2d, C), array(float64, 1d, C), array(float64, 1d, C))

    for i in range(r):
        dists = point_2_line_distance(front, np.zeros(n, dtype=np.float64), W[i, :])
        ^

My package versions:

• numba==0.53.1
• pymoo==0.6.1.3
• numpy==1.22.4

Im using the optimizer for a NxG sized array of floats ranging [0,1]. As feedback we get a Nx2 sized fitness array also ranging [0,1]. The approach works for all Pymoo MOO algorithms without numba.

If you need any further information LMK!

Made a fix that works for my case in #662. Seems to be general enough to be useful for all.

Just merged your PR! Thanks!

In case that should not fix it please re-open this issue. Note for testing it you will have to use the most recent main branch.
