c++ use python to import reverb error

[jzstudent]

python：

import traceback
import reverb
class RevervbUtil(object):
    # str,int,[str],int,int
    def init(self, learner_addr, learner_port, reverb_table_names,
             reverb_client_max_sequence_length, reverb_client_chunk_length):
        self.revervb_util = revervbutil(f'{learner_addr}:{learner_port}')
        self.reverb_table_names = reverb_table_names
        self.reverb_client_max_sequence_length = reverb_client_max_sequence_length
        self.reverb_client_chunk_length = reverb_client_chunk_length
    def send_datas(self, train_data):
        self.revervb_util.write_to_reverb_server_simple(self.reverb_table_names, train_data)

class revervbutil():
    def __init__(self, learner_addr) -> None:
        self.reverb_client = reverb.Client(learner_addr)
    def write_to_reverb_server_simple(self, reverb_table_names, train_data):
        try: 
            with self.reverb_client.writer(max_sequence_length=int(self.reverb_client_max_sequence_length), 
                                               chunk_length=int(self.reverb_client_chunk_length)) as writer:
                count = 0
                for sample in train_data:
                    for table in reverb_table_names:
                        writer.append(sample)
                        prioritezed = 1.0      
                        writer.create_item(table, 1, prioritezed)
                        writer.flush()
                    count += 1
        except Exception as e:
            print(f'learner_proxy send one data to reverb server error as {str(e)}, traceback.print_exc() is {traceback.format_exc()}')

c++：

#include "learner_proxy.h"

#include <python3.7m/Python.h>

using namespace std;

int main(int argc, char* argv[])
{
    //py::scoped_interpreter guard{}; 
    Py_Initialize();
    if(!Py_IsInitialized())
    {
        return -1;
    }

    PyRun_SimpleString("import sys");
        PyRun_SimpleString("sys.path.append('/data/projects/kaiwu-fwk/framework/server/cpp/src/aisrv/')");

    PyObject* pModule = PyImport_ImportModule("python_reverb_util");

    PyObject* pDict = PyModule_GetDict(pModule);
    PyObject* pClass = PyDict_GetItemString(pDict, "RevervbUtil");
    PyObject* pConstruct = PyInstanceMethod_New(pClass);
    PyObject* pInstanceReverb = PyObject_CallObject(pConstruct, NULL);
    
    return 0;
}

when I execute it, segment falut happens：

(gdb) bt
#0  0x00007fed93c8eb1a in tensorflow::kernel_factory::OpKernelRegistrar::InitInternal(tensorflow::KernelDef const*, absl::lts_2020_02_25::string_view, std::unique_ptr<tensorflow::kernel_factory::OpKernelFactory, std::default_delete<tensorflow::kernel_factory::OpKernelFactory> >) ()
   from /usr/local/python-3.7/lib/python3.7/site-packages/tensorflow/python/../libtensorflow_framework.so.2

#2  0x00007fed935a0d4f in _GLOBAL__sub_I_dataset.cc ()
   from /usr/local/python-3.7/lib/python3.7/site-packages/tensorflow/python/../libtensorflow_framework.so.2

Butttt, I can run the python file in python environment.

if __name__ == '__main__':
    revervb_util = RevervbUtil('127.0.0.1:9999', 1, 1)
    train_data = []
    revervb_util.write_to_reverb_server_simple('a', train_data)

How can I fix it? :>
