我通过pythonnet https://github.com/pythonnet/pythonnet
将Python嵌入到我的C#应用程序中我正在产生工作线程(一次一个),产生python子解释器在隔离环境和end sub intepreter中做一些工作。一切正常,直到我使用pymongo,然后Py_EndInterpreter开始失败。
Py_EndInterpreter(PyThreadState *tstate)
{
PyInterpreterState *interp = tstate->interp;
if (tstate != PyThreadState_GET())
Py_FatalError("Py_EndInterpreter: thread is not current");
if (tstate->frame != NULL)
Py_FatalError("Py_EndInterpreter: thread still has a frame");
if (tstate != interp->tstate_head || tstate->next != NULL)
Py_FatalError("Py_EndInterpreter: not the last thread");
PyImport_Cleanup();
PyInterpreterState_Clear(interp);
PyThreadState_Swap(NULL);
PyInterpreterState_Delete(interp);
}
失败
if (tstate != interp->tstate_head || tstate->next != NULL)
Py_FatalError("Py_EndInterpreter: not the last thread");
现在我真的不知道如何处理它并使代码工作。 我正在做的非常短的版本,正在失败是
Runtime.Py_Initialize();
Runtime.PyEval_InitThreads();
IntPtr thread_state = Runtime.PyEval_SaveThread();
IntPtr gil = Runtime.PyGILState_Ensure();
int i = 0;
while (i < 5)
{
AutoResetEvent resetEvent = new AutoResetEvent(false);
BackgroundWorker worker = new BackgroundWorker();
worker.DoWork += (o, ea) =>
{
Thread.Sleep(2000);
IntPtr interpreter = Runtime.Py_NewInterpreter();
string str = @"
import pymongo
client = pymongo.MongoClient(""localhost"")";
Runtime.PyRun_SimpleString(str);
Runtime.Py_EndInterpreter(interpreter);
resetEvent.Set();
};
worker.RunWorkerAsync();
resetEvent.WaitOne();
i++;
}
Runtime.PyThreadState_Swap(thread_state);
Runtime.PyGILState_Release(gil);
Runtime.PyEval_RestoreThread(thread_state);
Runtime.Py_Finalize();
答案 0 :(得分:1)
看起来pymongo会创建自己的线程(用于连接池),在这种情况下,控制解释器的状态并优雅地关闭它会更加困难。另一方面,尝试在脚本本身中执行此操作:
string str = @"
import pymongo
client = pymongo.MongoClient(""localhost"")
client.close()";
Doc说:
关闭()
断开与MongoDB的连接。
关闭连接池中的所有套接字,然后停止监视器 的线程强>
