Evolver Node Error

[frusaka]

Problem statement

I was trying to use the Evolver node but it seems to run into errors.

Steps to reproduce

I used the example from the documentation to make the shortest path that cycles through all points.

Actual result

When I tried to run it, I got this: Python: Traceback (most recent call last): File "C:\Users\Me\Documents\Blender scripts\addons\sverchok-master\utils\sv_operator_mixins.py", line 67, in execute response = self.sv_execute(context, node) File "C:\Users\Me\Documents\Blender scripts\addons\sverchok-master\nodes\logic\evolver.py", line 558, in sv_execute population.evolve() File "C:\Users\Me\Documents\Blender scripts\addons\sverchok-master\nodes\logic\evolver.py", line 526, in evolve self.population_g = self.get_new_population(actual_population_fitenss, mode) File "C:\Users\Me\Documents\Blender scripts\addons\sverchok-master\nodes\logic\evolver.py", line 457, in get_new_population weights = 1/np.power(np.array(fitness), self.node.fitness_booster) TypeError: unsupported operand type(s) for ** or pow(): 'str' and 'int'
