python - Open AI Gym with Neat Algorithm not working on Jupyter

# Use the NN network phenotype and the discrete actuator force function.

    for runs in range(runs_per_net):

        while not done:

            observation, reward, done, info = env.step(action)    
            fitness += reward

        fitnesses.append(fitness)

    return np.mean(fitnesses)

    for genome_id, genome in genomes:
        genome.fitness = eval_genome(genome, config)

    # the same directory as this script.
    config = neat.Config(neat.DefaultGenome, neat.DefaultReproduction,

    pop = neat.Population(config)
    stats = neat.StatisticsReporter()
    pop.add_reporter(stats)
    pop.add_reporter(neat.StdOutReporter(True))

    pe = neat.ParallelEvaluator(multiprocessing.cpu_count(), eval_genome)
    winner = pop.run(pe.evaluate)

    # Save the winner.

    print(winner)

    run()

Trying to run CartPole v1 with Neat Algorithm on jupyter notebook but the output is stuck on

**** Running generation 0 **** 

With increase in amount of GPU usage instead of the CPU.

But when trying to run it on CMD everything is working fine(GPU usage being normal). Is there any way I can do it on Jupyter Notebook.
