Hi,
I Need some of your help.
I have the following C code to import *Import python.* It works 99% of
the time, but sometimes receives "*ImportError('Error: Reinit is
forbidden')*". error.
**We run multiple instances of the app parallelly.

Hi,
Need some help,
in the Python, I have a array of string
var_array=["Opt1=DG","Opt1=DG2"]
I need to call c library and pass var_array as parameter
In the argtypes, how do I set up ctypes.POINTER(???) for var_array?
func.argtypes=[ctypes.c_void_p,ctypes.c_int, ctypes.POINTER()]

Hey,
Someone has discussed this issue before. Other than redirect stderr, does
the new version python 3.7.0 has other way to retrieve the string
whichPyErr_Print( ) ?
if (PyErr_Occurred())
PyErr_Print(); //need to retrieve the error to string
Thanks

Hi
Need some help.
I have a C++ application that invokes Python.
...
Py_SetPythonHome("python_path");
Py_Initialize();
This works fine on Python 3.6.4 version, but got errors on Python 3.7.0
when calling Py_Initialize(),
Fatal Python error: initfsencoding: unable to load the file system codec
Thanks Chris,
I think I figured it out that when build python on Linux, we need to
enable-shared.
Thanks again,

Hi,
This only works when loading modules from the current directory.
Is there a way I can load from somewhere else ?

Hi Chris,
Thanks a lot ! Using PyUnicode_DecodeUTF8 fix the problem.

Hi,
This is the case of calling python from c and the python function will

The message type is bytes, this may make different ?
