'module' object is not callable

[psosmol]

Hello, I have for files AllOnesGA.py with the main(), GeneticAlgorithm.py,Population.py and Individual.py
My problem is that when I try to run the program with pycharm an error message happens:
'module' object is not callable

the AllOnesGA.py is:
(thanks)

import GeneticAlgorithm
def main():
    ga = GeneticAlgorithm(100, 0.001, 0.95, 0)
    population = ga.initPopulation(50)
    ga.evalPopulation(population)
    generation = 1
    while ga.isTerminationConditionMet(population) == false:
        print("Best solution", population.getFittest(0).toString())
        population = ga.crossoverPopulation(population)
        population = ga.mutatePopulation(population)
        ga.evalPopulation(population)
        generation += 1
    print("Found solution in ", generation, " generations")
    print("Best solution:", population.getFittest(0).toString())
if __name__ == "__main__":
    main()

ps: the wrong lines are 3 and 16
