I am new to writing c++/python mixed programs.
I have compiled my_class.so (in c++) and can import it in python.
The following programs run without any problem.
#!/user/bin/env python
from my_class import *
l = my_class()
l.doSomething("filename")
I have everything under the same folder and if I start the python environment, I can do the following without any error
>>>import my_class
This is what I tried next, I tried to call python scripts from c++, the "hello" and "import numpy" part run successfully without any problem.
Next I tried something purely experimental, I want to test the possibility, but I don't expect any real application, I want to import my own class. like the following(I know I am creating a c++/python/c++ chain):
#include <Python.h>
int main(int argc, char *argv[]){
Py_Initialize();
//PyRun_SimpleString("print \"hello!\"");
//PyRun_SimpleString("import numpy");
PyRun_SimpleString("import my_class");
Py_Finalize();
return 0;
}
I got the following error:
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named my_class
This is not a total surprise, since my_class is not a standard module and I probably need to tell the python runtime inside c++ program where to find this module.
But I am not sure how I can do it. I assume at least I can try to "install" my_class.so as a custom module in python's standard path, but I wonder if there is any simpler solution. Thanks!
