Stopped process is still running - pawlaczkaj - Apr-06-2018 I have got a menu written in Python: if __name__ == '__main__': print_menu() # display the menu choice = input("Type number") if choice == 1: function1() # function, which calls the other functions if choice == 2: function2()I had run function1 and before it reached the end I had stopped the script in terminal with Ctrl+C (I use Ubuntu 16.04). After it I want to check function2, but when I am running the script with menu, the menu is not displayed and it goes immediately to function1. It looks like the function1 is running whole the time, but when I check processes with ps ax there is not my script. How can I terminate running function1? RE: Stopped process is still running - woooee - Apr-06-2018 It depends on what is in function1. Are you using subprocess or multiprocessing to start a separate process? If you are using Python3.x, neither option will be run. RE: Stopped process is still running - pawlaczkaj - Apr-07-2018 Function1 and function2 are collision avoidance algorithms which are sending to the simulator. They control the robot's moving as long as it reachs the goal. I use only functions with loops. I am new in Python, so I don't know subprocess and multiprocessing. I have the same problem when I use Python2.x and Python3.x too. RE: Stopped process is still running - woooee - Apr-07-2018 Then you have no process that continues after the program exits (Ctrl+c kills everything). RE: Stopped process is still running - pawlaczkaj - Apr-07-2018 If Ctrl+c kills everything, why after new running script, it doesn't display menu, but it runs function1? RE: Stopped process is still running - Gribouillis - Apr-07-2018 After Ctrl-C, the program should print an exception traceback If it doesn't do that, there is another error somewhere.
RE: Stopped process is still running - pawlaczkaj - Apr-07-2018 But I have got this output. I think there is another problem. Ctrl+c should "reset" the whole program and come back to start. Right? When I run the same scripts, which are called in the menu, without the menu's script and I use ctrl+c everything is ok. I mean programm stop and when I run it again, it starts from the beginning. So in that case should I use subprocess or multiprocessing? RE: Stopped process is still running - Gribouillis - Apr-08-2018 If you have this output, it means that the program exited. If the program does not start other processes or threads, there is nothing left of this program's execution. I don't understand your description with the menu: which menu are you talking about? Are you running the script from an IDE or from a terminal? Try to run the program from an ordinary terminal. RE: Stopped process is still running - pawlaczkaj - Apr-08-2018 I have got menu.py with code from my first post. Also I have got algorithms' scripts: algorithm1.py and algorithm2.py. They are called in menu.py in function1 and function2. At the beginning of my coding I wrote algorithms' scripts and I checked them. Everything worked as it should - after ctrl+c script ends and when I run it again, it starts from the script's first line. But when I test menu.py, I have a problem mentioned in posts - after ctrl+c script ends and when I run it again, it starts from the script's middle (it goes to the algorithm that was interrupted). I run my scripts from terminal. RE: Stopped process is still running - Gribouillis - Apr-08-2018 I think it can be debugged only if you post the complete code, or a link to the code. |
