Python + C/C++ 嵌入式编程：Qt向Python传递数组?报错

编程环境Qt5.7.1 MSVC版，VS2013，python3.7.1，我使用Qt像python传递字节数组，Qt和python代码如下，当多次点击按钮多次调用（第二次调用时）python程序时，提示程序异常结束。


Qt程序：
INCLUDEPATH +=D:/Python3.7.3/include
INCLUDEPATH += D:/Python3.7.3/Lib/site-packages/numpy/core/include
LIBS += -LD:/Python3.7.3/libs/ -lpython37
int init_numpy()
{
import_array();
}
void MainWindow::on_ButtonNumpy_clicked()
{
Py_Initialize();//使用python之前，要调用Py_Initialize();这个函数进行初始化
init_numpy();
if (!Py_IsInitialized())
{
printf("初始化失败！");
return ;
}
PyRun_SimpleString("import sys");
PyRun_SimpleString("sys.path.append('./')");//这一步很重要，修改Python路径
PyObject pModule = PyImport_ImportModule("demo2");//这里是要调用的文件名hello.py
PyObject pDict    = PyModule_GetDict(pModule);
if (pModule == NULL)
{
printf("Can't open python file\n");
return ;
}
//PyObject pFunc = PyObject_GetAttrString(pModule, "szSecTest");
double CArrays[3][3] = {{1.3, 2.4, 5.6}, {4.5, 7.8, 8.9}, {1.7, 0.4, 0.8}};
qDebug()<<"rrr";
npy_intp Dims[2] = {3, 3};
//生成包含这个多维数组的PyObject对象，使用PyArray_SimpleNewFromData函数，第一个参数2表示维度，第二个为维度数组Dims,第三个参数指出数组的类型，第四个参数为数组
PyObject PyArray  = PyArray_SimpleNewFromData(2, Dims, NPY_DOUBLE, CArrays);
PyObject ArgArray = PyTuple_New(1);
PyTuple_SetItem(ArgArray, 0, PyArray);
PyObject pFunc = PyDict_GetItemString(pDict , "Test");//这里是要调用的函数名
// PyObject * pFunc = PyObject_GetAttrString(pModule , "Test");
if (!pFunc){
printf("Get function hello failed\n");
return ;
}  PyObject *pRrturn = PyObject_CallObject(pFunc, ArgArray);   qDebug()<<pRrturn;    PyArray = NULL;   ArgArray = NULL;   pRrturn = NULL;   pModule=NULL;   pDict=NULL;   Py_Finalize();
}
python程序：import numpy as np
def Test(test):
print (test.shape,test[0], test[1],test[2])
