阅读量:

The 'freeze_support()' line is unnecessary if the program is not intended to be frozen for generating an executable file.

 RuntimeError:

    
     An attempt has been made to start a new process before the
    
     current process has finished its bootstrapping phase.
    
  
    
     This probably means that you are not using fork to start your
    
     child processes and you have forgotten to use the proper idiom
    
     in the main module:
    
  
    
         if __name__ == '__main__':
    
             freeze_support()
    
             ...
    
  
    
     The "freeze_support()" line can be omitted if the program
    
     is not going to be frozen to produce an executable.

解决方法:将调用代码转移至主函数模块(main函数)中运行即可实现目标

复制代码
 if __name__ == '__main__':

    
     #程序代码

即可
