Relaunch a python script stopped by a CTRL+Z and containing a Fortran executable launched by os.system

I was running a Python script which launches several times a Fortran executable (with os.system('./executable params.ini).

Unfortunately, I did a CTRL+Z to stop the python script but it seems that I have stopped it during the execution of the Fortran executable.

Now, impossible to relaunch the Python script. I tried. :

fg %1

and 

bg %1

and 

kill -CONT pid_of_executable

But nothing happens ...

So, is there a way to relaunch the python script ? I am frustrated ... if anyone could save my life ... (I am joking)

UPDATE 1: Once Python script stopped by CTRL+Z, pa aux | grep compute gives :
