差异演化因工人而产生错误= -1

问题描述

我使用Scipy的差分进化来使用OMPython运行一些模拟。我在Windows和Jupiter Notebook上工作。

当我仅使用1个处理器时，我的代码有效。但是，当我使用选项workers=-1时，代码冻结（尽管目录中生成了一些文件），但出现以下错误。

from multiprocessing import Process,freeze_support
from scipy.optimize import differential_evolution

def Optimization_Modelica_General('arguments'):
    'Some code'
    Solution_GEN=differential_evolution(Optimization_Modelica,bounds=bounds_2,args= 
    ('args'),updating='deferred',workers=-1)


if __name__ == "__main__":
    from pathos.helpers import freeze_support
    freeze_support()
    
    Result_Gen_Final=Optimization_Modelica_General('arguments')

错误消息：

您是否会知道问题出在哪里？我尝试使例程中使用的函数腌制，但是仍然出现相同的错误。预先感谢。
