2 years ago I notice this:
When I run in omnet my simulation, the command is:
Command line: ../../src/AIBasedOffloadings -m -n ..:../../src:../../../inet/src:../../../inet/examples:../../../inet/tutorials:../../../inet/showcases:../../../resources/veins-master/examples/veins:../../../resources/veins-master/src/veins --image-path=../../../inet/images:../../../resources/veins-master/images -l ../../../inet/src/INET -l ../../../resources/veins-master/src/veins omnetpp.ini
In makefile in src, there are:
# Other makefile variables (-K)
INET_PROJ=../../inet
VEINS_PROJ=../../resources/veins-masterSo I tried to do the following:
#!/usr/bin/env python3

But, despite I indeed have a file in src folder called aibasedoffloadings (actually AIBasedOffloadings[86_64/le], when I run, it says:
Args: {'debug': False, 'tool': None, 'verbose': False, 'arguments': None}
Omnet Args: ['-uCmdenv', '-cMultipleGymsOne', '--seed-set=0', '--*.manager.seed=0', '--*.gym_connection.port=5551']
I go run now!
Running with command line arguments: "sudo" "../src/aibasedoffloadings" "-l../../../resources/veins-master" "-l../../../inet" "-n../ .;../../../resources/veins-master;." "-n../ .;../../../inet;." "--image-path=../../../resources/veins-master/images" "--image-path=../../../inet/images" "-uCmdenv" "-cMultipleGymsOne" "--seed-set=0" "--*.manager.seed=0" "--*.gym_connection.port=5551"
sudo: ‘../src/aibasedoffloadings’: No such file or directory
It doesn't find. This run script is in simulations, it is the runX one being called by run.sh.
I want to argue that those double libs and images will cause some problem, but it doesn't seems to be the problem now. Despite I have there compiled the aibasedoffloadings, it doesn't find it when I try to run.
Thank you!
Sorry for bothering you again, Mr Bose.
When I was using veinsgym, I changed that run.sh in a way to run my scenario directly, a compiled file in the root of the project. It worked fine there.
But now I created another project with src and simulations (one of the defaults of the omnet). So there exists a file also called run with the following content in simulations dir (it's name is "run" but I will write runX to make easier to understand in the figure below):
This is done by omnet. When I copy my veinsgym scenario in the simulations folder, it will have its name, say, rltask and inside of it I put the run.sh and the .ini file (alongside with the .ned files).
If I try to use the default run from omnet referencing it in run.sh, the python scripts starts but keeps hanging on the listening part. However everything is alright, as they are the same files that worked before with the rltask when I was running directly from the root in the other open project. So I already know it should work, but if I try to run using the default run script of omnet, it hangs.
I believe you have a reason to have created that particular run you shared along both serpentine and dcc, so maybe you know why this is happening.
I would like also to say that, in this project I am Project Referencing INET and VEINS, they aren't libs in a subdirectory inside the project, but opened and built projects on a different dir. I am saying this because, in both serpentine and dcc, the script "run" Mr Bose wrote considers a lib dir with veins inside, for instance. I am not quite sure how to modify the script to take into account these differences as INET and VEINS are referenced and outside project dir. I tried to use the default run because of this.
(In my other project, run.sh would have exec ../rltask "$@", and rltask-[x86_84/le] compiled file was copied in the root dir of the project, and by that I know it is not in the python script or in the omnet .ned, .cc,.h files I used, as it is working fine).
Either way Mr Bose could help me, I will be glad.
I hope it is something simple.
