About the changes in omnetpp.ini file about serpentine-env HOT 8 CLOSED

Hi @serapergun,

I am having some trouble understanding precisely what your problem is.
What I understand is: You want to modify the omnetpp.ini configuration file (e.g., using a different application type) but the simulation appears unchanged.

Maybe, you are having issues with how configuration overwriting works in OMNeT++ (best match wins) see the manual.

For debugging, it might be helpful to run the Veins/OMNeT++ simulation separately and with the QtEnv GUI enabled, so you can inspect the details. See the Readme of veins-gym on how to do that.
Aside from that, I would need more description or (even better) an example of a changed omnetpp.ini file to understand what might be the issue.

Best,

Hi @dbuse,
Firstly, thank you for quick replay.
You understood me exactly right.
I wrote a new application type about decision making and a new car module.I want to use them.

For example I changes as follow:

network = HeteroScenario
*.manager.moduleType = "serpentine.HeteroGenericNode"
.node[].applType = "DecisionMakerApp"
*.gym_connection.action_space = "gym.spaces.Discrete(2)"

In random_agent file, I added this line:
"user_interface": "Qtenv",

thanks to this line, I saw GUI perfectly. And also the results of rewards and observations in Console.

However, I could not see the effects of my added files.

So the simulation still uses the previous network/moduleType/applType/etc.?
Did you change the lines in the omnetpp.ini file or add your own at the bottom (potentially in a different config)?

Maybe providing the full diff of the omnetpp.ini file or pushing your changes to github could help. There is many places where these issues may be coming from.

@dbuse

I just changed the 4 lines in the omnetpp.ini file (in the previous comment) which is under serpentine-env/scenario.

I add project reference as SimulTE. And I used the nodes from there by importing as:
import lib.veins.src.veins.nodes.HeteroNodeCar;

from serpentine-env.

So in the GUI, if you clock on the node[0] element in the canvas and check its configuration in the explorer on the left, its applType is still the default and not your "DecisionMakerApp"?

Again, this is hard do tell from what and how you have posted it.

Though this seems to be a problem located only within the Veins/OMNeT++ side of the system. So you could run your Veins scenario without an agent and inspect/debug it to investigate the error.

Hello
I am trying to replicate the serpentine-env code using Ubuntu 18.04 virtual machine. The requirements installed were Sumo 1.6.0, Omnet++ 5.6.2, and protoc version libprotoc 3.5.0. I have some problems with protoc version. The message is "This file was generated by an older version of protoc which is". Can you tell me the protoc version that you use to test and implement the serpentine env.

Hi @andresq99
for our demo environment in the docker container, we successfully used the following version

$ docker run -it --rm  ghcr.io/tkn-tub/veins-gym:0.3.3 protoc --version
libprotoc 3.6.1

from serpentine-env.

I forgot to write here.
Whenever I made a change in ini file about gym, I figure out that it should be run snakemake -jall to set environment.
I'm sharing it in case if there is someone who needs it and lost their months like me.
Thanks,
