使用Python API PyArray_SimpleNewFromData时内存泄漏

Question

我无法在以下代码中找出内存泄漏的原因; Valgrind在执行以下功能时报告内存。由于我对Py_INCREF和Py_DECREF宏缺乏了解，可能会发生这种情况。

这里是c ++代码

if (process.argv.length < 3) {
   console.error("A file path is required");
   process.exit(1);
}

这里是Python函数

#include <stdio.h>
#include <Python.h>
#include "numpy/arrayobject.h"
#include <ctime>
#include <iostream>
using namespace std;

int main() {
    PyObject *pName = NULL;
    PyObject *pModule = NULL;
    PyObject *pFunc = NULL;
    PyObject *pArgs = NULL;
    PyObject *pValue = NULL;
    PyObject *vec = NULL;
    PyObject *vec1 = NULL;

    const char* script = "TestScript";
    const char* function = "test";

    Py_Initialize();
    pName = PyUnicode_FromString(script);
    pModule = PyImport_Import(pName);

    // Deleting memory for object pName
    Py_DECREF(pName);

    import_array1(-1);

    if (pModule != NULL) {
        pFunc = PyObject_GetAttrString(pModule, function);

        if (pFunc && PyCallable_Check(pFunc)) {
            // define a vector
            double* v = new double[5];
            v[0] = 1.0;
            v[1] = 2.0;
            v[2] = 3.0;             
            v[3] = 4.0;             
            v[4] = 5.0;

            double* v1 = new double[5];
            v1[0] = 1.0;
            v1[1] = 2.0;
            v1[2] = 3.0;                
            v1[3] = 4.0;                
            v1[4] = 5.0;

            npy_intp vdim[] = { 5 };

            vec = PyArray_SimpleNewFromData(1, vdim, (int)PyArray_DOUBLE, (void*)v);
            vec1 = PyArray_SimpleNewFromData(1, vdim, (int)PyArray_DOUBLE, (void*)v1);

            pArgs = PyTuple_New(2);
            Py_INCREF(vec); // If I don't do this, I get segfault in Py_Finalize**
            Py_INCREF(vec1); // If I don't do this, I get segfault in Py_Finalize**

            PyTuple_SetItem(pArgs, 0, vec);
            PyTuple_SetItem(pArgs, 1, vec1);


            pValue = PyObject_CallObject(pFunc, pArgs);

            Py_DECREF(pArgs);
            Py_XDECREF(vec);
            Py_XDECREF(vec1);

            delete [] v;
            delete [] v1;

            if (pValue != NULL) {
                printf("Result of call: %f\n", PyFloat_AsDouble(pValue));
                Py_DECREF(pValue);
            }

            Py_DECREF(pFunc);
        } else {
            if (PyErr_Occurred()) {
                PyErr_Print();
                fprintf(stderr, "Cannot find function \"%s\"\n", function);
            }
        }
        Py_DECREF(pModule);
    } else {
        PyErr_Print();
        return 1;
    }

    Py_Finalize();

    return 0;
}

这里是Valgrind报告的摘要。

def test(a, b):
    print("Python::test")
    print(a)
    print(b)

    return 1
