stack smashing calling python function importing tensorflow c++ -


i new tensorflow including python code in c++, therefore apprechiate tips/comments on following weird behaviour: have c++ class pythoninterface headerfile pythoninterface.h:

#include <string> #include <iostream>  class pythoninterface{ private:     const char* file;     const char* funct;     const char* filepath;  public:     pythoninterface();      ~pythoninterface();      void callfunction(); };

the sourcefile pythoninterface.cpp:

#include <python.h> #include <string> #include <sstream> #include <vector> #include "pythoninterface.h"  pythoninterface::pythoninterface(){      file = "tensorflowincludepy";     funct = "mytestfunction";     filepath = "/path/to/tensorflowincludepy.py"; }  void pythoninterface::callfunction(){     pyobject *pname, *pmodule, *pdict, *pfunc, *pvalue, *presult;     // initialize python interpreter    py_initialize();     //set in path find custom python module other path python's system modules/packages found.    std::stringstream changepath;    changepath << "import sys; sys.path.insert(0, '" << filepath << "')";    const std::string tmp = changepath.str();    filepath = tmp.c_str();    pyrun_simplestring (this->filepath);      // build name object    pname = pystring_fromstring(this->file);     // load module object    pmodule = pyimport_import(pname);     if(pmodule != null) {    // pdict borrowed reference        pdict = pymodule_getdict(pmodule);          // pfunc borrowed reference        pfunc = pydict_getitemstring(pdict, this->funct);         if (pycallable_check(pfunc))        {            pvalue=py_buildvalue("()");            printf("pvalue empty!\n");            pyerr_print();            presult=pyobject_callobject(pfunc,pvalue);            pyerr_print();        } else        {            pyerr_print();        }        printf("result %d!\n",pyint_aslong(presult));        py_decref(pvalue);         // clean        py_decref(pmodule);        py_decref(pname);    }    else{        std::cout << "python retuned null pointer, no file!" << std::endl;    }     // finish python interpreter    py_finalize(); }

and python file function should included (tensorflowincludepy.py):

def mytestfunction():     print 'i function without input!'     gettingstartedtf()     return 42   def gettingstartedtf():     import tensorflow tf #at point error occurs!     hello = tf.constant('hello, tensorflow!')     sess = tf.session()     print(sess.run(hello))     return 42

finally in main function create pythoninterface object p , call function p.callfunction(). communication between c++ , python code works right, when (at runtime) line import tensorflow tf reached, *** stack smashing detected *** error message , program finishes. can guess problem might or had similar issue before?

i know there c++ tensorflow api, feel more comfortable using tensorflow in python thought might perfect solution me (apparently not...:p)

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

go - golang pprof for c library code -

i have been trying profile golang application pprof, seems details of c code(linked static library) missed in output result. flame graph from frame graph can see c code time consuming reported within "runtime._externalcode", no details @ all. , sure static library compiled debug enable. so there way make pprof details(like stack trace) of 3rd party c code? or there other golang profiling tool this?
