NEAT Error - AttributeError: 'tuple' object has no attribute 'connections'

问题

I'm currently trying to create a NEAT algorithm to solve FlappyBird but am coming across an error while running my code (see title). Currently I have set up my run function and my eval_genomes functions. I've simplified them to remove the pygame stuff and tried to keep it just to the neat-python relevant bits.

I know there are ways I could make this better, but I can someone help in finding how to solve the error I'm seeing below.

The error seems to stem from the neat-python module, but I've uninstalled and reinstalled it so there isn't anything wrong with the module. I've run someone else's code and there's works so again module seems to work fine.

def run(config_path):
    config = neat.config.Config(neat.DefaultGenome, neat.DefaultReproduction,
                         neat.DefaultSpeciesSet, neat.DefaultStagnation,
                         config_path)

    p = neat.Population(config)

    p.add_reporter(neat.StdOutReporter(True))
    stats = neat.StatisticsReporter()
    p.add_reporter(stats)

    winner = p.run(eval_genomes,20)

def eval_genomes(genomes, config):
    run = True
    game = Game(WIN)

    nets = []
    ge = []
    birds = []

    for g in genomes:
        net = neat.nn.FeedForwardNetwork.create(g, config)
        nets.append(net)
        birds.append(Bird(WIN))
        g.fitness = 0
        ge.append(g)

    while run:
        if len(birds) = 0:
            run = False
            break

        for x, bird in enumerate(birds):
            bird.move()
            ge[x].fitness += 0.1

            output = nets[x].activate((bird.y,
                                      abs(bird.y - game.pipes[pipe_ind].height),
                                      abs(bird.y - game.pipes[pipe_ind].bottom)))

            if output[0] > 0.5:
                bird.jump()

        for x, bird in enumerate(birds):
            if game.check_collisions(bird):
                ge[x].fitness -= 1
                birds.pop(x)
                nets.pop(x)
                ge.pop(x)

        if game.pipe_passed(birds[0]):
            for g in ge:
                g.fitness += 5

        game.update()                        # Move all the other pieces
