More Python Embedding Trouble

[jibarra]

I'm trying to run a basic C/Python API, I am using Python3.6
https://docs.python.org/3.6/extending/em...n-overview

My Python File Looks like

import numpy as np
#import random
class Multiply:
    def __init__(self):
        self.x = 2
        self.y = 2
        self.a = 0

    def multiply(self):
        self.a = self.x * self.y
        print("Result of: {} * {}".format(self.x,self.y))
        return self.a

My C File Looks Like

#include </usr/include/python3.6m/Python.h>
#include <stdio.h>
#include <stdlib.h>

int
main(int argc, char *argv[])
{
    PyObject *pName, *pModule, *pClass;
    PyObject  *pValue, *pDict, *pInstance;

    int i, arg[2];

    Py_Initialize();

    PyRun_SimpleString("import sys");
    PyRun_SimpleString("sys.path.append(\".\")");


    pName = PyUnicode_DecodeFSDefault("with_numpy_import");
    pModule = PyImport_Import(pName);
    pDict = PyModule_GetDict(pModule);

    pClass = PyDict_GetItemString(pDict, "Multiply");

    Py_DECREF(pName);

    if (PyCallable_Check(pClass)){
    pInstance = PyObject_CallObject(pClass, NULL);
    }


    if( argc > 4 ){
      for (i = 0; i < argc - 4; i++){
          arg[i] = atoi(argv[i + 4]);
  }

      pValue = PyObject_CallMethod(pInstance, argv[3], "(ii)", arg[0], arg[1]);

  }else{
      pValue = PyObject_CallMethod(pInstance, "multiply", NULL);
  }

  if(pValue != NULL){
      printf("Return of call : %d\n", PyLong_AsLong(pValue));
      Py_DECREF(pValue);
  }else{
  PyErr_Print();
  }

  // Clean up
  Py_DECREF(pModule);
  Py_DECREF(pDict);
  Py_DECREF(pInstance);
  Py_DECREF(pClass);

  Py_Finalize();

  //////// Start Over ////////

  Py_Initialize();

  PyRun_SimpleString("import sys");
  PyRun_SimpleString("sys.path.append(\".\")");


  pName = PyUnicode_DecodeFSDefault("with_numpy_import");
  pModule = PyImport_Import(pName);
  
  

  return 0;
}

Why do I get a segmentation error when I import numpy? I can import random and it runs perfectly fine after I comment out import numpy. I have observed that this segmentation error occurs when I use modules that have been brought in with pip.

Is it safe to assume I can run Py_Initialize(); and Py_Finalize(); multiple times in one program?

Please advise.
