PyRun_File 's Invoke problem

I am working at centos7.9,
here is python,c and env info:

python version: 3.6.8 (default, Jun 20 2023, 11:53:23) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-44)]

When I use PyRun load a python script. if I add scipy.stats modules in .py
the calling thread will be hanging. the .py script is like this:

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
# paramsIn => resultOut 
# from jsonStr => j =  bytearray(byte_data);sonStr
# author: fengxh Sep04,2023

import json
import binascii
import numpy as np;
import sys
# the next  two lines all could make PyRun_File hang....
#from scipy.stats import kurtosis  #cannot exec in python c envirmento.
#import scipy as sci

Even I havn’t use scipy function at all, the calling will be hanging…

Try connecting gdb to the hung process and look at the stack to see what is going on.
