How to create a custom population?

[pritam-dey3]

I want to create a custom population with each chromosome/solution will be a pandas DataFrame. How should I create initial_population values and what should be assigned to gene_type attribute?

This is an example.

import pygad
import numpy

def fitness_func(ga_instanse, solution, solution_idx):
    return numpy.sum(solution)

ga_instance = pygad.GA(num_generations=5,
                       num_parents_mating=2,
                       initial_population=[[1,2], 
                                           [5,7]],
                       gene_type=[int, float],
                       fitness_func=fitness_func)

ga_instance.run()
