在 PyGad 中抑制打印纪元

Question

我正在使用 Pygad 通过遗传算法训练 Keras NN，据我所知代码有效，但是，我不知道如何防止它在终端中打印纪元：

ga_instance = pygad.GA(num_generations=15, num_parents_mating=5, fitness_func=fitness_func, 
initial_population=keras_ga.population_weights, on_generation=on_generation, suppress_warnings=True)

正如你在这里看到的，我已经设置了suppress_warnings=True，然而，当我运行ga_instance.run()时，终端将继续打印这些文本：

1/1 [==============================] - 0s 34ms/step
1/1 [==============================] - 0s 36ms/step
1/1 [==============================] - 0s 34ms/step
1/1 [==============================] - 0s 36ms/step
1/1 [==============================] - 0s 31ms/step
1/1 [==============================] - 0s 29ms/step
1/1 [==============================] - 0s 29ms/step
1/1 [==============================] - 0s 29ms/step
1/1 [==============================] - 0s 29ms/step
1/1 [==============================] - 0s 37ms/step
1/1 [==============================] - 0s 38ms/step
1/1 [==============================] - 0s 33ms/step
1/1 [==============================] - 0s 34ms/step
1/1 [==============================] - 0s 32ms/step
1/1 [==============================] - 0s 31ms/step
1/1 [==============================] - 0s 29ms/step

我不确定这个问题是由 PyGad 还是 Tensorflow 引起的，但我想不出解决这个问题的方法。

感谢您的宝贵时间。

Answer 1

检查 fitness 和 on_generation 函数，如果您使用任何打印语句并删除它们。

否则，PyGad 不会自行打印输出，除非有警告或错误。

并且您已经阻止了抑制警告

suppress_warnings：bool参数，控制是否打印警告信息。它默认为假。查看文档以获取有关参数的更多信息：https://pygad.readthedocs.io/en/latest/README_pygad_ReadTheDocs.html
