python-embedding

问题 I am fairly new to python and a real beginner to tkinter and matplotlib. I have the following code which essentially is a testbed for what I eventually want to do. #!/usr/bin/env python import numpy as np from matplotlib import pyplot as plt import time top = 100 plt.ion () # set plot to animated xdata = [] c = 0 for a in range(0,top): xdata.append(a) c+=1 ydata = [ 0 ] * top * 10 ax1 = plt.axes () c = 0 myfile = open("rdata.txt", "r") for myline in myfile: q = myline ydata[c] = q c+=1 c = 0

问题 I am trying to embed python 3.7.0 in a C++ application and use MinGW to compile. #include "Dependencies/include/Python.h" int main() { PyObject* myPointer; Py_Initialize(); return 0; } I compile with this: g++ ./TestEmbedding.cpp I get this error: undefined reference to `_imp__Py_Initialize' 回答1: You need to build with Python headers: g++ TestEmbedding.cpp `python3-config --includes` -o TestEmbedding 回答2: EDIT: Found and Answer: The path to the python libs file needs to be included. I

问题 Creating a python module with swig is the easy part. But what if this module has to interact with my C++ application that imports it from its embedded python instance? For example @Flexo has made a pretty good example on how to expose the python module to the application here: How can I implement a C++ class in Python, to be called by C++? All I want is that the application and the module are able to interact with each other like sharing variables and calling callbacks and so on so I found

问题 Consider the following code running embedded Python script from C++. It create an embedded Python module with a function that will report current file/line upon execution. #include <Python.h> #include <iostream> #include <fstream> PyObject * mymodule_meth_test(PyObject * self) { PyTraceBack_Here(PyEval_GetFrame()); PyObject * exc; PyObject * val; PyObject * tb; PyErr_Fetch(&exc, &val, &tb); PyTraceBack_Print(tb, PySys_GetObject("stderr")); std::cout << "LINE is " << PyLong_AsLong(PyObject

问题 I have a c++ facerecognition code and a python code in opencv. In python code i read frames from a robot and i want to send this fram to my c++ code. I use this link tho call python function in c++ function. my c++ function is embed.cpp: #include <Python.h> #include <stdlib.h> #include "opencv2/core/core.hpp" #include "opencv2/contrib/contrib.hpp" #include "opencv2/highgui/highgui.hpp" #include <iostream> #include <fstream> #include <sstream> #include </home/nao/Desktop/python/boost_1_61_0
