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…
why?

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

It seems I encountered deadlock.
Does PyRun_File() support async_invoke_interface?

Its not documented as supporting async.
