Runtime Error while twice usage (Trac #2203) #656
Description
Original ticket http://projects.scipy.org/numpy/ticket/2203 on 2012-08-17 by trac user Lukasz16a, assigned to unknown.
The following simple code causes runtime error:
# include <Python.h>
# include <numpy/arrayobject.h>
void f() {
import_array() ;
}
int main() {
for(int i=0 ; i<2 ; i++) {
Py_Initialize() ;
f() ;
Py_Finalize() ;
}
}The problem is loading numpy.core... I tested it on Visual Studio 2010 at Windows 7 Professional x64.

Hmm, looks like a strange construct. I'm inclined to close this unless you can provide a normal example where it fails.

IIRC it is not expected that
import_arraycan be called twice. We can reopen when someone notes why it should work or has a use case.mattip commentedon Jan 5, 2019
This is important for subinterpreters. If PEP 554 gets accepted we may want to revisit this. But it is fine to close this as there are enough other issues open about
Py_Finalize,
