嵌入python和运行多次

问题描述

我使用boost :: python嵌入python，这是我怎么做：

  void runCode {
 Py_Initialize（）; 
 // boost :: python代码在这里和嵌入式python代码运行
 Py_Finalize（）; 
} 
  

它第一次运行很好，但是当它再次运行时，我发生此错误：

$ b

解决方案

因为你没有得到一个专家回答，我提供我的学习从一个类似的问题。
Python对有问题。这是不幸的，如果你需要重新启动解释器由于一些错误，或者想要运行许多独立的解释器。

一个问题有泄漏的资源和内存以上链接）：

不正确地支持这一点，例如可以看出。 我认为这是你面对的问题。

看起来大多数Python应用程序都可以解决这个问题：

• 使引擎在专用进程中运行;


• 使用。 / ul>
  
  

  如果第二个适用于您，请继续。

  
  

  I'm using boost::python to embed python, this is how I do it:

  void runCode(){
      Py_Initialize();
      //boost::python code goes here and embedded python code runs
      Py_Finalize();
  }
  

  it runs nicely for the first time, but when it is run again, I get this error:

  and code does not run as expected, any help is appreciated.

  解决方案

  Since you didn't get an expert answer, I'm offering my learning from working on a similar problem.Python have issues with reinitialization support. This is unfortunate if you need to restart the interpreter due to some error, or want to run many independent interpreters.

  One issue there is leaking resources and memory (quoting from the above link):

  Another issue is many modules don't support this properly, as can be seen for example in this SO thread. I think this is the problem you're facing.

  It seems that most Python applications work-around this problem:

  • by having the engine run in a dedicated process ;
  • by using subinterpreters which represent distinct execution states (of a common interpreter)

  If the second one works for you, go ahead with it.
