在嵌入C++应用程序的解释器中导入pyomo.inveron模块时崩溃

Question

我试图用PyoMo程序包在复杂的C++应用程序中进行一些计算。嵌入式Python解释器运行的C++模块是共享库，它是主应用程序的插件。主应用程序使用dlopen/dlsym调用插件

环境：

-Debian 10.3 x86_64

-Python v.3.7.3（默认值）

-通用条款第5.8.3.0节

该错误发生在导入pyomo.environ子包时：

#include <Python.h>
...
Py_Initialize();
PyRun_SimpleString("import pyomo.environ");

在执行PyRun_SimpleString("import pyomo.environ");字符串后，我看到以下输出：

澄清： 只有当解释器在动态加载的共享库中运行时，才会出现此问题。若我直接从python或解释器（嵌入到独立测试应用程序中）启动python代码，那个么一切都会按预期工作
